FUNDAMENTO: análisis de la aplicación de un ciclo de garantía de calidad sobre las tasas de infección nosocomial (IN) en una UCI polivalente de nivel II. MÉTODO: Estudio prospectivo de cohortes, de dos años de duración, sobre 568 pacientes; Grupo A (n=281), observacional y Grupo B (n=287), en el que se aplicaron medidas de mejora (administración de sucralfato, correcta profilaxis antibiótica quirúrgica y medidas estrictas de asepsia) Se comparan las tasas de IN asociada a ventilación mecánica (NAVM), sonda uretral, catéter venoso central e infección de herida quirúrgica en ambos grupos, así como la estancia y mortalidad intra-UCI. RESULTADOS Tras la aplicación del ciclo de mejora de calidad mediante el cumplimiento de criterios de calidad, obtuvimos una reducción significativa de las tasas de incidencia de todas las infecciones controladas. No apreciamos diferencias en la mortalidad global intra-UCI entre ambos grupos, aunque sí en los que desarrollaron una IN. Los pacientes con NAVM, mostraron una reducción no significativa de la mortalidad. El subgrupo de pacientes que recibió sucralfato presentó una disminución de la frecuencia de IN y mortalidad relacionada. Sin embargo, el grado de incumplimientos del protocolo de mejora se mostró elevado (diagrama de Pareto). CONCLUSIONES: La instauración de un sistema de vigilancia y la aplicación de medidas de mejora han logrado reducir tanto la incidencia como la mortalidad de la IN, no así la mortalidad global intra-UCI. / BACKGROUND: To analyze the effects of implementation of a quality assurance cycle on rates of nosocomial infection (NI) in a level II intensive care unit (ICU.) METHOD: Prospective cohort study of two years on 568 patients divided in Group A (n = 281, cohort observational control group) and Group B (n = 287; experimental cohort group), which were implemented improvement measures (administration of oral sucralfate, surgical prophylaxis and aseptic measures). We compare the rates of follow aspects: ventilator-associated pneumonia (VAP), urethral catheter, central venous catheter and surgical wound infections, length and ICU mortality in both groups. RESULTS: After the implementation of quality improvement cycle by meeting quality criteria, we obtained a significant reduction in incidence rates of all infections under control. We found no differences in overall mortality ICU between the two groups, except in those who developed one NI. Patients with VAP showed a non significant reduction in mortality. The subgroup of patients receiving sucralfate showed a decrease in the frequency of NI and related mortality. However, the degree of improvement protocol violations was high (analyzed by Diagram’ s Pareto). CONCLUSIONS: The establishment of a surveillance system and implementation of improvement measures have reduced both the incidence and mortality of NI, but not the overall ICU mortality.

Ziel: Ziel dieser Studie war es, Risikofaktoren für operationsbezogene postoperative Infektionen (SSIs) nach spinalen Eingriffen zu identifizieren und die Wirksamkeit einer perioperativen Antibiotikaprophylaxe zur Vermeidung von Infektionen zu ermitteln. Methoden: Von Januar 2002 bis März 2004 erfolgte eine retrospektive Analyse neurochirurgischer Eingriffe unter dem Ausschluss kranieller Operationen. Untersuchte Risikofaktoren waren dabei Diagnose und Art der Operation sowie Höhe des Eingriffs an der Wirbelsäule, Alter und Geschlecht, Operationsdauer, postoperative Krankenhausliegedauer (LOS) und verlängerter Aufenthalt auf der Intensivstation (ITS). Weiterhin wurden die Wirksamkeit und der Umgang mit einer perioperativen Antibiotikaprophylaxe beobachtet. Die Infektionsrate von SSIs und anderen postoperativen Nosokomialinfektionen stellte das ausschlaggebende Kriterium dafür dar, dass ein Risikofaktor als solcher definiert wurde. Ergebnisse: Die Gesamtinfektionsrate von SSIs lag bei 2,29% (34 von 1484). Parallel zu der Komplexität der Operationen wurden zunehmende Infektionsraten festgestellt: Bandscheibenvorfall (3,48%), Spinalkanalstenose (3,97%), spinales Trauma (4,55%), spinaler Tumor (12,5%). Wesentliche Risikofaktoren waren dabei Operationsdauer (> 2 Stunden), LOS (> 7 Tage), Aufenthalt auf der Intensivstation (> 48 Stunden). Das Alter bei spinalen Eingriffen wurde auch, im Gegensatz zu Geschlecht und der Eingriffshöhe an der Wirbelsäule, als ein Risikofaktor gewertet. Bei Anwendung einer perioperativen Antibiotikaprophylaxe erhöhte sich die Infektionsrate (1,35% auf 6,06%; p <0,01). Der Einsatz einer perioperativen Antibiotikaprophylaxe wurde mit komplexeren Operationen, beispielsweise Eingriffen bei spinalen Tumoren, mit Eingriffen bei jüngeren (≤30 Jahre) oder älteren (>60 Jahre) Patienten, mit Eingriffen mit hohen Infektionsraten und mit Eingriffen mit Risikofaktoren (Operationsdauer, LOS, ITS) verbunden. Mit einem kurzen (≤24 Stunden) Protokoll der Prophylaxe im Vergleich zu einem längeren (>24 Stunden)zeigten sich niedrigere Infektionsraten (2,5% gegenüber 10%, p = 0.006). Die Antibiotikaprophylaxe erfolgte größtenteils mit Cefazolin (76,47%) und es wurden überwiegend grampositive Mikroorganismen, Haupterreger Staphylococcus aureus, isoliert. Eine Verschiebung des Verhältnis zugunsten der gramnegativen und zu Lasten der grampositiven Erreger zeigte sich bei Eingriffen mit ITS Aufenthalt, bei Eingriffen mit Durchführung einer perioperativen Antibiotikaprophylaxe und in Kombination mit postoperativen Allgemeininfektionen. Abgesehen von den Eingriffen mit Aufenthalt auf ITS, stellten die grampositiven Erreger zahlenmäßig weiterhin die dominanten Erreger dar. Schlussfolgerung: Risikofaktoren in der spinalen Chirurgie wurden identifiziert und deren Berücksichtigung hilft SSIs und deren Komplikationen zu verhindern. Es gab kein Anzeichen dafür, dass eine perioperative Antibiotikaprophylaxe SSIs reduziert. Eine Prophylaxe wurde auf komplexere Operationen mit einem höheren Risikoprofil limitiert und sollte einem kurzen Anwendungsprotokoll folgen. Im Zusammenhang mit der zunehmenden Anzahl komplexer chirurgischer Verfahren mit steigenden Infektionsraten bei gleichzeitig wachsender Resistenzentwicklung muss die Rolle der perioperativen Antibiotikaprophylaxe kritisch gesehen werden und sollte weiterführend untersucht werden.

The Diploma thesis provides basic information about the incidence of nosocomial infections, especially about the process of spreading infections, their subdivision according various aspects, major means of nosocomial infections, and about methods of surveillance. Investigative part of the thesis is aimed to describe the incidence of nosocomial infection, which can be used as quality indicator of hospital care, including the spectrum of the most frequent etiological microbial agents and their resistance against antibiotic treatment. There were used mixed research methods to process the investigative part of the thesis because the methods were quantitative and qualitative. The analysis of the data represents main part of the thesis. The research was carried out in the district hospital, namely in The Hospital Strakonice, a.s.. There were monitored infections at operation sites, between Jan 1, 2011 and Dec 31, 2011 at the surgical and gynaecology units. There were also monitored infections of the blood stream between Jan 1, 2009 and Dec 31, 2011 at all departments. The research group was formed by inpatients staying in The Hospital Strakonice, a.s., who were after surgical procedure or those, who were catheterized central blood stream in defined time period.

Seu objetivo foi definir as taxas de prevalência e mortalidade desses espisódios, identificar as espécies envolvidas e relacionar a freqüência dos fatores de risco entre adultos e recém-nascidos (RNs), bem como entre os episódios de candidemia por Candida albicans (CA) e por Candida não-albicans (CNA). A metodologia Incluiu os casos de forma consecutiva, à medida que foi detectada hemocultura positiva para esses fungos. A coleta de dados dos pacientes foi realizada com base no prontuário médico, por meio de formulário padronizado e analisados utilizando o programa Social Package Statistical Science e englobando 45 casos de candidemia, sendo dezenove casos (42%) em neonatos. Foi observado que a incidência de candidemia nosocomial no HUCAM foi de 2,0/10.000 pacientes-dia, 1,9/1.000 altas e 16/10.000 admissões, sendo maior nos pacientes internados em unidades de terapia intensiva. As espécies não-albicans predominaram e Candida parapsilosis foi mais incidente entre os RNs; os grupos de pacientes susceptíveis mais envolvidos foram aqueles com internação em torno de três semanas, com síndrome séptica aguda e em uso de antibióticos; a freqüência dos fatores de risco foi similar entre os adultos e os RNs, assim como entre os episódios devidos a CA e os devidos a CNA; maior utilização de nutrição parenteral total foi encontrada entre os RNs e de diálise, entre os adultos (p < 0,05); a taxa de mortalidade global foi de 44% entre os adultos e de 58% entre os RNs; e a taxa de mortalidade atribuída foi de 16% entre os adultos e 26% entre os RNs. Foi concluído que a incidência de candidemia no HUCAM foi alta e associada com substancial mortalidade. / This work was a descriptive study, which described the episodes of nosocomial candidemias occurring at Hospital Universitário Cassiano Antônio de Moraes (HUCAM), between March 1st, 2003 and February 28th, 2006. Its aim was to define the rates of prevalence and mortality of these epidsodes, to identify the species involved and to relate the frequency of the risk factors among adults and newborn (NBs), as well as the epidsodes among candidemias caused by Candida albicans (CA) and Candida non-albicans (CNA). The methodology included the cases in a consecutive way, as positive hemoculture was detected for these fungi. The date collection of patients was based on the medical records, through a standard form and it was analyzed using the Social Package Statistical Science program, including 45 cases of candidemias, being nineteen cases (42%) in NBs. It was observed that the incidence of nosocomial candidemia at HUCAM was 2.0/10.000 patient-day, 1.9/1.000 discharges and 16/10.000 admissions, being greater in patients interned in intensive therapy unity. the CNA predominated and C. parapsilosis was more incidente among the NBs; the group of susceptible more involved were those interned for 3 weeks with acute septical syndrome and in use of antibiotics; the frequency of risk factor was similar among the episodes due to CA and the ones due to CAN; greater utilization of total parenteral nutrition was found in the NBs and the dialysis, among the adults (p< 0,005); the total mortality rate was 44% among adults and 58% among the NBs. And the attributed mortality rate was 16 in adults and 26% in NBs. It was concluded that incidence of candidemias at HUCAM was high and associated with substantial mortality.

Since 90% of participants who received only the intervention had skin protected from colonizing bacteria, unlike subjected to the bath in the conventional bed, which showed 80% of positive cultures. Statistical analysis showed that, whereas the microbial load of the participants in Group B decreased with disposable intervention, increased significantly in Group A, who had received baths in conventional bed (p <0.001). Conclusions. Bed bath with the use of disposable technology, tested brand, proved to be significantly effective on the microbial load of the skin of hospitalized patients, when compared to conventional bath. The hypothesis of disposable bed bath present shorter run time and lower costs when compared with the conventional has been refuted. It is recommended to carry out further studies on these variables, to understand their importance on the design of human resources in nursing, as well as the decision by hospital supplies choices. / FAPESP: 2014/25099-2

Handwashing frequency may result in harmful effects on the skin, promoting the increase of the prevalence of nosocomial important microorganisms. This study purpose was to assess the quantitative and qualitative changes of the total microbiota (both permanent and transient) from hands of nursing professionals and university laboratory technicians and students due to the irritant action provoked by frequent washing and/or wearing gloves. Sixty health professionals were enrolled from whom collections were performed by the sterile polyethylene bag, before and after washing hands with 3 mL of nonantimicrobial soap for 30 seconds. In the group formed by students and laboratory technicians (n=30), these collections were performed before and after consecutive washings with water and soap. Damaged hands health professionals hands contamination was higher when compared with healthy hands. Hygiene proved to be efficient in both students and laboratory technicians without complaints of irritation after successive washings, a fact not seen among health care workers. Nurses with damaged hands presented higher frequency of S. aureus, Gram negative bacteria and yeast than the healthy ones (P>0.05), as well as the sum of these microorganisms (P=0.07) and presence of S. haemolyticus (P=0.02). The frequency of S. aureus and antimicrobial resistant Gram negative bacteria was higher among nurses damaged hands. The irritation caused on the skin by the frequent washing and/or wearing of gloves may cause changes of hands microbiota and should be considered when choosing hygiene products. / A freqüência da lavagem de mãos pode resultar em efeitos prejudiciais na pele promovendo aumento da prevalência de microrganismos de importância hospitalar. Os objetivos deste trabalho foram avaliar quantitativa e qualitativamente as alterações na microbiota total (residente e transitória) das mãos de profissionais de enfermagem e estudantes universitários e técnicos de laboratório associadas à ação irritante provocada pela freqüente lavagem e/ou uso de luvas. Foram incluídos 60 profissionais de saúde, nos quais foram realizadas coletas, pelo método do saco estéril de polietileno, antes e após a lavagem com 3 mL de sabão não medicamentoso, por 30 segundos. No grupo constituído por estudantes e técnicos de laboratório (n=30), estas coletas foram realizadas antes e após lavagens consecutivas com água e sabão. A contaminação das mãos de profissionais de saúde com danos na pele foi maior em relação às sadias. A higiene se mostrou eficiente nos estudantes e técnicos de laboratório sem queixas de irritação após lavagens sucessivas, fato não observado entre profissionais de saúde. Enfermeiras com mãos com danos apresentaram maior freqüência de S. aureus, bacilos Gram-negativos e fungos leveduriformes do que as sadias (P>0,05), assim como quanto à soma destes microrganismos (P=0,07) e a presença de S. haemolyticus (P=0,02). A freqüência de S. aureus e bacilos Gram-negativos resistentes aos antibióticos foi maior nas mãos lesadas de enfermeiras. A irritação causada na pele devido à lavagem freqüente e/ou uso de luvas pode provocar alterações da microbiota das mãos e deve ser considerada pelas instituições quando da escolha de produtos de higiene. / Mestre em Imunologia e Parasitologia Aplicadas

Sepsis represents a serious medical, but also social problem. Hundreds of thousands of patients die from serious sepsis and septic shock every year. Patients with serious sepsis are treated at intensive care units and their treatment is long, costly and low efficient. These are the reasons why prevention of sepsis focused on prevention and effective treatment of nosocomial infections or timely solution of another problem, e.g. a shock is so much stressed. Nosocomial infections affect about 30 per cent of patients at intensive care units and may cause serious diseases, sepsis or even death. This thesis deals with the possibilities nurses have to influence sepsis, particularly by adherence to aseptic procedures and prevention of nosocomial infection, which might consequently develop in nosocomial sepsis. Combination of quantitative and qualitative methods was used for the research. There were two goals set for the quantitative research. 1. To find whether obstacles occur in adherence to proper aseptic procedures in nursing work as prevention of nosocomial infection occurrence and subsequent septic conditions in patients hospitalized at intensive medicine workplaces. 2. To map the weak points in adherence to proper aseptic procedures in nursing work in intensive care. The goals led to hypotheses H1 Obstacles obstructing thorough adherence to proper aseptic procedures in nursing work exist in intensive care. H2 Non-adherence to aseptic procedures occurs in nursing work at intensive medicine workplaces as a consequence of lack of time for particular interventions. The research sample consisted of nurses from the intensive care workplaces ARD and ICU from 8 hospitals. Questioning method through the questionnaire technique was used for data collection. 342 questionnaires were distributed in total. Hypothesis 1 was refuted, hypothesis 2 was refuted. We found that no obstacles obstructing adherence to proper aseptic methods occur, we mapped the weak points in adherence to proper aseptic procedures in nursing work in intensive care. There were two goals set for the qualitative research. GOAL 3 To find what measures preventing occurrence of nosocomial infection and subsequent septic conditions in patients hospitalized at intensive medicine workplaces are taken by department managements. GOAL 4 To find out how department management deals with possible occurrence of nosocomial infection and subsequent septic conditions in patients hospitalized at intensive medicine workplaces. The following research questions were set. 1. What are the measures preventing occurrence of nosocomial infection and subsequent septic conditions in patients hospitalized at intensive medicine workplaces taken by department managements? 2. How does department management solve possible occurrence of nosocomial infection and subsequent septic conditions in patients hospitalized at intensive medicine workplaces? The research sample consisted of 5 departmental nurses and 5 head nurses from intensive care workplaces from the same hospitals where the quantitative research took place. The research was performed by semi-standardized interview. The research questions were answered. A manual for nurses called ?Recommendation for nurses in prevention of nosocomial infection and nosocomial sepsis not only at intensive care units? was elaborated upon study of these issues and the performed research. A thought map for department management illustrating prevention and solution of nosocomial infection and nosocomial sepsis was also elaborated. Both the document and the research results will be provided particularly to the managements of the hospitals that took part in our research. The thesis may also be helpful to nurses, students and other interested people to gain overall insight into the issue.

Estudo de desenvolvimento metodológico de elaboração e validação de medidas de avaliação em saúde, que teve como finalidade contribuir com novas políticas de controle e prevenção de infecção hospitalar (CIH). Para tanto, foram construídos e validados três indicadores de avaliação de práticas de controle e prevenção da infecção hospitalar do trato urinário associada a cateter, conforme duas etapas metodológicas. Na primeira, tendo como referência bases conceituais de indicadores clínicos e medidas de avaliação em saúde, foram elaborados os indicadores: 1-Indicação e Permanência do Cateterismo Vesical (IUIC); 2- Condições de Manutenção do Cateterismo Vesical (IUMN) e 3- Infra-Estrutura para Procedimento de Cateterismo Vesical (IUIF). Na segunda etapa estes indicadores foram submetidos à validação de conteúdo, por meio de um método de validação opinativa de um grupo de nove especialistas, constituído de médicos e enfermeiras, com conhecimento e experiência em controle de infecção hospitalar, e representantes das áreas hospitalar, acadêmica, órgão governamental e entidades associativas. A validação foi realizada com o julgamento de cada indicador a partir de um instrumento previamente elaborado, que contemplava as seguintes etapas: I- Conteúdo do construto (manual operacional) do indicador; II- Atributos do conjunto do indicador; III- Componentes do indicador. O indicador 3 foi submetido, ainda, a mais uma etapa, referente à valoração, pelos juízes, de cada um de seus componentes. Foi previamente estabelecido um consenso mínimo de 75% de julgamento favorável dos juízes, de cada uma destas etapas. Em cada etapa solicitava-se também comentários e sugestões para ajuste dos indicadores. Nos resultados, os indicadores 1 e 2 obtiveram consenso favorável mínimo na grande maioria dos aspectos sob avaliação de cada etapa. Nos aspectos que não obtiveram consenso favorável mínimo as sugestões e comentários efetuados pelos juízes tornaram possível o ajuste destes indicadores e sua validação de conteúdo, sem necessidade de retorno aos juízes para novo julgamento. O indicador 3, apesar de ter obtido amplo consenso favorável nas etapas II e III, o mesmo não ocorreu em vários aspectos referentes à etapa I, assim como na valoração de relevância dos seus componente individuais. Além disto, os comentários e sugestões efetuados constataram a problemática deste indicador para avaliar adequadamente o que ele se propunha. Por este motivo, ele não pôde ser validado, na forma de construção originalmente apresentada. / This is a study on the methodological development of elaboration and validation of measures to evaluate health aiming to contribute to new control rules and to prevent nosocomial infection (CIH). Then, three evaluation indicators of control and prevention of nosocomial infection in the urinary tract associated to a catheter were built in accordance with two methodological phases. In the first phase, based on the conceptual basis of clinical indicators and evaluation measures in health, the indicators were elaborated: 1 - Indication and Permanence of Vesical Catheterism (IUIC); 2 – Maintenance Conditions of Vesical Catheterism (IUMN) and 3 – Infrastructure for procedures of Vesical Catheterism (IUIF). In the second phase, these indicators were submitted to a content validation by means of a validation method according to one group of nine experts, constitued of physicians and nurses, with knowledge and experience in nosocomial infection and representatives of the hospital, academic and governmental areas and associative institutions. The validation was performed according to judgment of each indicator based on a instrument previously elaborated, consisting of: I- Construct Content (operational guidebook) of the indicator; II- Features of the indicator set; III- Components of the indicator. The indicator 3 was still submitted to one more phase regarding valorization of each component, according to the judges. A minimum consensus of 75% of favorable arbitration from the judges was previously established for each phase. In each phase it was also asked comments and suggestions to adjust indicators. In the results, indicators 1 and 2 obtained a minimum favorable consensus in the great majority of the evaluating aspects for each phase. The aspects which did not obtain the minimum favorable consensus, suggestions and comments made by the judges made possible an adjustment of these indicators and their content validation, with no need of the judges to return for a new arbitration. The indicator 3, in spite of obtaining a comprehensive favorable consensus in the phases II and III, the same did not occur in many aspects of the phase I as well as in the relevance valoration of its individual components. Additionally, the comments and sugestions performed, considered the problematic of this indicator to adequatly evaluate its objective. Therefore, it could not be validated on its original construction.

Introdução - A urbanização desencadeia inúmeros transtornos, como a disseminação de artrópodes e, conseqüentemente, de doenças veiculadas pelos mesmos. As formigas são muito adaptáveis e se beneficiam com a convivência humana. Nos hospitais, elas podem ser vetores mecânicos de inúmeras bactérias, e a diversidade de espécies encontradas nestes ambientes, causam preocupação pelo risco potencial à saúde pública. O aumento das infecções hospitalares envolvendo micobactérias ambientais, com surtos no Brasil entre 1998 a 2009 em 23 estados alarmou os órgãos e profissionais de saúde pública. Objetivos - Avaliar o potencial de formigas como vetores de micobactérias em um hospital especializado no atendimento de doentes com tuberculose. Métodos - Foram realizadas seis coletas de formigas em diferentes áreas do hospital no período de 2009 a 2010, que foram semeadas em meios de cultura de Löwenstein-Jensen e de Stonebrink para isolamento de micobactérias. As culturas sugestivas foram submetidas à coloração de Ziehl-Neelsen para bacilos álcool-ácido resistentes e identificação por métodos moleculares (PRA para o gene hsp65 com o par de primers TB11 e TB12 gênero-específico e sequenciamento genético do DNA). Resultados - Do total de 247 amostras de formigas coletadas e semeadas, 70 por cento das formigas pertenciam à espécie Tapinoma melanocephalum, 25 por cento a espécie Dorymyrmex sp., 3 por cento a espécie Camponotus sp. e 2 por cento a espécie Pheidole sp., dados similares foram observados anteriormente em pesquisas realizadas em hospitais. Quinze amostras apresentaram bacilos álcool-ácido resistentes de crescimento rápido. Nos métodos moleculares, doze pertenciam ao Gênero Mycobacterium. No PRA-hsp 65, e no sequenciamento genético do DNA, quatro amostras foram identificadas quanto à espécie (duas Mycobacterium chelonae, uma Mycobacterium parafortuitum e uma Mycobacterium murale), quatro micobactérias com resultados idênticos no PRA e não identificadas no sequenciamento foram sugestivas de uma nova espécie, e duas amostras não foram identificadas. Mycobacterium chelonae isolada nesta pesquisa foi previamente descrita como agente causador de abscessos em humanos. Conclusão - Estes dados confirmam a presença de micobactérias veiculadas por formigas no ambiente hospitalar, representando um potencial vetor mecânico destas para pacientes e profissionais de saúde, principalmente em infecções nosocomiais / Introduction- Urbanization triggers numerous disorders, such as the dissemination of arthropods and, consequently, dissemination of diseases transmitted by them. Some ant species are very adaptable to the human environment. At hospitals, once they are mechanical vectors of bacteria, and the diversity of species found in these environments, they can represent a potential risk to public health. The increase of nosocomial infections involving environmental mycobacteria, with outbreaks in Brazil from 1998 to 2009 in 23 states called the interest of health professionals and health agencies. Purpose - Evaluate the potential of ants as vectors of mycobacteria in a hospital specialized in the care of patients with tuberculosis. Methods Samples of ants were collected from different areas of the hospital from 2009 to 2010, and workers were inoculated in Löwenstein-Jensen and Stonebrink media for mycobacteria isolation. The suggestive cultures were subjected to Ziehl-Neelsen stain for acid-fast bacilli and identification were performed by molecular methods (PRA for the hsp65 gene with the pair of primers TB11 - TB12 and genetic sequencing). Results - The total of 247 samples of ants collected and sown, 70 per cent belonged to species of ants Tapinoma melanochepalum, 25 per cent Dorymyrmex sp.,3 per cent Camponotus sp. and 2 per cent Pheidole sp., data similar with previous studies conducted in hospitals. Fifteen fast-growing mycobacteria were isolated. In molecular methods, twelve belonged to the genus Mycobacterium. In PRA-hsp65, and the genome sequencing of DNA, four samples were identified at species level (two Mycobacterium chelonae, one Mycobacterium parafortuitum and one Mycobacterium murale), four mycobacteria with similar results in the PRA and not identified in the sequencing, suggestive of a new species and two unidentified samples. M. chelonae was previously reported as causative agent of abscess in humans. Conclusions - These results confirm the presence of mycobacteria carried by ants in the hospital, representing a potential mechanical vector for these patients and healthcare professionals, particularly in nosocomial infections
