Estudio retrospectivo de caso control de ehrlichiosis canina en la Facultad de Medicina Veterinaria de la Universidad Mayor de San Marcos : periodo 2002-2005

Contreras Samanez, Ana María Giovanna January 2006 (has links)
La ehrlichiosis canina es reconocida como una enfermedad infecciosa importante de distribución mundial y potencialmente fatal de los perros y otros miembros de la familia Canidae. Es ocasionada por Ehrlichia canis y transmitida por la garrapata marrón del perro Rhipicephalus sanguineus. El objetivo de este trabajo fue realizar un estudio retrospectivo de tipo casocontrol para evaluar los factores de riesgo asociados a la presentación de ehrlichiosis canina en pacientes de la Clínica de Animales Menores y del Laboratorio de Patología Clínica de la FMV - UNMSM. Con este fin se utilizaron datos de historias clínicas entre los años 2002-2005, de los cuales se consiguieron tanto los casos (caninos con ehrlichiosis: n igual 50) como los controles (caninos sin ehrlichiosis: n igual 100). Los datos recolectados fueron agrupados según raza, sexo, edad, antecedente de garrapatas y lugar de origen, y fueron analizados mediante la prueba de Chi2 para ver la asociación entre las variables. Se estimaron los odds ratios (OR) crudo y ajustado para saber el grado de riesgo de las variables en estudio. La enfermedad se presentó en 15 razas distintas. De los casos, el 50% fue de raza grande, 72% fueron machos, el 68% fue mayor de 2 años y el 82% presentó garrapatas. Los factores de riesgo asociados con la enfermedad fueron: razas grandes (OR igual 12.8, p igual a 0.024), raza Pastor alemán (OR igual 12.2, p menor a 0.01), edad (menor a 2-4 años: OR igual 4, p igual 0.008) y antecedente de garrapatas (82% (48/50) para los casos y 1% (1/100) para los controles). Palabras Claves: E. canis, garrapata, caso-control, factores de riesgo, odds ratio. / Canine ehrlichiosis is well known as a worldwide, very important and potentially fatal infectious disease of dogs and other members of the canidae family. It is caused by Ehrlichia canis and transmitted by the brown dog tick Rhipicephalus sanguineus. The aim of this work was to make a retrospective case-control study in order to evaluate the risk factors associated with the presence of canine ehrlichiosis in dogs from the Clínica de Animales Menores y Laboratorio de Patología Clínica de la FMV-UNMSM. For this purpose, cases (dogs with ehrlichiosis: n igual a 50) as well as controls (dogs without ehrlichiosis: n igual a 100) from clinic charts data among the years 2002-2005 were used. The data recollected was grouped by breed, sex, age, ticks history and place. Chi square, odds ratio (OR), and logistic regression were performed. Fifteen different breeds were seen. From the cases, a 50% large breeds, 72% males, 64% older than 2 years, and 82% ticks were found. The risk factors associated with the disease were large breeds (OR igual a 12.8, p igual 0.024), German shepherd dog (OR igual a 12.2, p menor a 0.01), age (menor a 2-4 years: OR igual a 4, p igual a 0.008) and ticks history (82% (48/50) for the cases and 1% (1/100) for the controls).

Evidencia hematológica y serológica de Ehrlichia spp. en propietarios de caninos domésticos con antecedentes de ehrlichiosis en Lima Metropolitana

Barrios Arpi, Luis Manuel January 2010 (has links)
La Ehrlichiosis es una zoonosis que ha sido identificada en muchos países de América Latina y el mundo entero. Esta enfermedad ocasiona alteraciones hematológicas y bioquímicas en los pacientes afectados. Los estudios reportados en el Perú muestran valores variables de seropositividad en relación a la enfermedad. En el presente estudio se determinó la presencia de seropositividad a Ehrlichia canis mediante la prueba de Inmunofluorescencia indirecta (IFI) en pacientes humanos y la evaluación hematológica respectiva en cada uno de ellos y su asociación con variables de sexo, edad, exposición a garrapatas y nivel de contacto con perros mediante la prueba de Chi Cuadrado. Se evaluaron 91 sujetos sin distinción de sexo, edad o condición socioeconómica cuyos perros tenían historia de erliqiosis reciente (máximo 6 meses previos al muestreo), los cuales llenaron una encuesta con datos clínico-epidemiológicos de importancia. El muestreo fue realizado entre los meses de febrero y mayo en el Laboratorio de Patología Clínica de la FMV-UNMSM y en los domicilios de cada uno de los pacientes; mientras que, el procesamiento de las muestras se ejecutó en dicho Laboratorio y en la Section de Virología del Laboratorio de Microbiología y Parasitología de dicha facultad. Los resultados de la evaluación hematológica mostraron ausencia de pacientes positivos, habiendo 15.38% de pacientes sospechosos (presencia de corpúsculos de inclusión en células mononucleares y ausencia de trombocitopenia). El porcentaje de pacientes seropositivos por IFI fue de 14.29%, no encontrándose significancia estadística a la prueba de Chi Cuadrado (p menor 0.05) con las variables de interés. Estos hallazgos confirman la exposición a Ehrlichia canis en propietarios de caninos domésticos con antecedentes de Ehrlichiosis en Lima Metropolitana, sin evidenciar asociación de los resultados con los factores de riesgo evaluados. / Ehrlichiosis is a zoonotic disease found in many Latin American countries and worldwide as well. The disease causes hematological and biochemical changes in affected patients. Studies reported in Peru show variable seropositivity values related to this disease. In this study, we evaluated seropositivity and hematologic changes in human subjects by indirect Inmunofluorescent test (IFI) and hematology. We tested the results against risk factors such as sex, age, ticks and dog contact using the Chi-Square test. Ninety-one samples were collected from patients with no difference related to socioeconomic status, age or sex whose dogs had recent history of ehrlichiosis (6 months preview to the sampling) and were asked to fill out a survey with these information. Data recopilation was done between february and may of 2010 at the FMV-UNMSM Clinical Pathology Laboratory and at the subject’s home when necessary. Samples were processed in this laboratory as well as in the Virology Unit of the Microbiology and Parasithology Laboratory. Hematology results revealed an absence of positive cases and 15.38% of suspected cases (showing presence of inclusions bodies within the cytoplasm of mononuclear cells and absence of thrombocytopenia). The IFI seropositive patients were 14.29%, without statistic relevance to the Chi Square test (p menor 0.05) compared to any of the risk factors considered above. These findings confirm exposition to Ehrlichia canis in dog owners with previous record of Ehrilichiosis in Lima Metropolitana, without statistical relationship between tests results and the risk factors evaluated.

Distribution and prevalence of Ehrlichia chaffeensis, the causative agent of human monocytic ehrlichiosis, in Indiana and Ohio

Irving, Ryan Powell January 1999 (has links)
Human monocytic ehrlichiosis (HME) is a tick-borne infectious disease caused by the bacterium Ehrlichia chaffeensis and transmitted by the ixodid tick Amblyomma americanum. The first confirmed case of HME in Indiana occurred in 1994. Since then, there have been an additional 17 confirmed cases reported from 11 counties.A total of 498 A. americanum and 25 Dermacentor variabilis ticks were collected from counties in southern Indiana during May and June 1998, pooled, and examined for the presence of E. chaffeensis using nested PCR with primers HE 1 and HE3, which are specific for the 16S rRNA gene of E. chaffeensis. Ten pools of adult A. americanum specimens tested positive for E. chaffeensis DNA. This represented a minimum infection rate (MIR) of 3.82%. None of the A. americanum nymphs or adult D. variabilis ticks tested positive.In addition, 325 white-tailed deer blood samples from Indiana and 327 from Ohio were collected during November, 1998 and tested for the presence of E. chaffeensisreactive antibodies using an indirect immunofluoescence assay (IFA). Evidence of such antibodies was found in deer killed in six Indiana counties where infection rates ranged from 43% - 64% and four Ohio counties where infection rates ranged from 4% - 25%.The results from this study support the view that the distribution of E. chaffeensis closely follows that of A. americanum in the North Central United States. This is the first report of E. chaffeensis-reactive antibodies in white-tailed deer from Ohio. / Department of Biology

Evaluación del exámen hematológico y la técnica indirecta de ELISA en el diagnóstico clínico-laboratorial de Ehrlichiosis canina

Hoyos Sifuentes, Luis Antonio January 2005 (has links)
La Ehrlichiosis canina es una enfermedad causada por diversos microorganismos rickettsiales, principalmente Ehrlichia canis. Está reportada alrededor del mundo como una enfermedad zoonótica y en el Perú fue detectada en 1982. El diagnóstico clínico se basa en la detección de signos, tales como depresión, fiebre, anorexia, mucosas pálidas, pérdida de peso, linfadenopatía, hifema y eritema. En el laboratorio clínico, la hematología, bioquímica sanguínea, uroanálisis y pruebas serológicas son de gran utilidad en el diagnóstico definitivo. En el presente estudio se determinó el grado de concordancia entre el examen hematológico y la técnica indirecta de ELISA, ya que la relación entre ambas pruebas es desconocida en nuestro medio. 97 perros fueron obtenidos provenientes del Laboratorio de Patología Clínica en la Facultad de Medicina Veterinaria de la Universidad Nacional Mayor de San Marcos. Se encontró un 84.67 ± 10.98% de grado de concordancia. Asimismo, se determinó que la trombocitopenia, leucopenia, anemia y el antecedente de garrapatas fueron estadísticamente significativos (P es menor que 0.05) en relación a la presencia de la enfermedad. El porcentaje de Ehrlichiosis canina en perros cruzados y de raza Pastor Alemán fue mayor en relación a las demás razas. Los perros de raza nórdica (Siberiano y Samoyedo) presentaron significancia estadística a padecer cuadros hemorrágicos por esta enfermedad. Finalmente, se encontró una concordancia alta entre ambas pruebas, estos resultados evidencian que en nuestro país la hematología es de gran importancia en el diagnóstico de la Ehrlichiosis canina, quedando la serología como prueba de apoyo en casos confusos. / Canine Ehrlichiosis is a disease caused by different rickettsial microorganisms, principally by Ehrlichia canis. It has been reported around the world like a zoonotic disease and in our country was detected in 1982. The clinic diagnosis is based in detection of signs like depression, fever, anorexia, pallor of mucous membranes, lost of weight, lymphadenophaty, hiphema and erythema. In Clinical Laboratory, the hematology, sanguineous biochemistry, urine-analysis and serologic tests are usefulness in definitive diagnosis. The present study determinated the concordance grade between the hematology test and indirect ELISA assay, because la relationship between both tests is unknown in our country. 97 dogs were obtained from the Clinical Pathology Laboratory in Veterinary Medicine Faculty of San Marcos National University. We are found 84.67 ± 10.98% of concordance grade. Likewise, was determinated that thrombocytopenia, leukopenia, anemia and tick contact antecedent were significant (P is less than 0.05) in relation with evidence of disease. The percent of cross-breed dogs and German Shepherd dogs (GSDs) with Canine Ehrlichiosis was higher than other breeds. The hemorrhage signs were statistic significance only in Nordic races (Siberian Husky and Samoyedo). Finally, we found a high concordance grade between both tests, this results reveal that hematology in our country is very important in the Canine Ehrlichiosis diagnostic and serology is a support test in confuse cases.

The occurrence and distribution of ehrlichia chaffeensis in ticks in Southern Indiana

Burket, Christopher T. January 1996 (has links)
In 1994 and 1995, seven cases of Human monocytic ehrlichiosis were reported in Indiana; six cf these were from southern counties. To test whether Ehrlichia cha ffeensis is present in native ticks, adult ticks representing two species, Dermacentor variabilis and Amblyomma americanum were collected in southern Indiana during the first week of May, 1995 and tested by PCR. A total of 510 D. variabilis ticks were collected and placed into 102 pools (5 ticks per pool). A total of 430 adult A. americanum ticks were collected and placed into 88 pools of 5 ticks or less.D. variabilis ticks were used to optimize the isolation of PCR amplifiable DNA and determine the minimum number of bacterial cells detected. A modified CTAB-phenol method permitted the detection of as few as 100 bacterial cells. The optimal amount of isolated DNA for a PCR amplification was determined to be 2.7 pg of total nucleic acid.The 88 pools of adult A. americanum were subjected to DNA isolation, PCR amplification, and Southern analysis to determine the presence of E. chaffeensis bacteria. Using the 16S rRNA gene from E. chaffeensis, with species specific primers Hut and HE3. Of the 88 pools (430 ticks; 21 were determined to be positive for the presence E. chaffeensis bacteria. Thus, minimal field infection rate for adult A. americanum ticks in Southern Indiana was 4.88%. This calculation is based upon the assumption that at least one tick was positive in each positive pool. / Department of Biology

O curso da enfermidade é dividido em três fases: aguda, subclínica e crônica. O objetivo deste estudo foi avaliar as lesões anatomopatológicas que ocorreram no parênquima e no endotélio vascular do encéfalo, coração, pulmão, fígado, rim, baço e linfonodo mesentérico de 16 cães que vieram a óbito acometidos pela EMC na fase crônica. Esses animais apresentaram sinais clínicos neurológicos, porém na avaliação microscópica não exibiam lesões que justificassem esses sintomas. No coração foi possível notar a presença de alterações vasculares visíveis, como Coagulação Intravascular Disseminada, necrose dos miócitos próximos a esses vasos, congestão e hemorragias devido à severa trombocitopenia desenvolvida durante a infecção. No pulmão notou-se pneumonia em grande parte dos animais estudados. O fígado também se apresentou acometido, mas não diretamente pela infecção, mas sim por consequência de outros fatores prejudiciais relacionados à doença. Em todos os rins avaliados a glomerulonefrite se mostrou presente. Em todos os 16 animais pode-se notar a esplenomegalia. O linfonodo mesentérico não é uma estrutura muito estudada em animais com EMC, mas pode-se notar um grande infiltrado plasmocitário. No entanto, cocluiu-se que a vasculite foi responsável por grande parte das lesões, sendo predominante o infiltrado plasmocitário / Canine Monocytic Ehrlichiosis (CME) is an infectious disease, potentially fatal, caused by Ehrlichia canis, transmitted by Rhipicephalus sanguineus. The course of the disease is divided into three stages: acute, chronic and subclinical. The aim of this study was to evaluate the pathological lesions that occurred in the parenchyma and the vascular endothelium of the brain, heart, lung, liver, kidney, spleen and mesenteric lymph node of 16 dogs that died affected by CME in the chronic phase. These animals showed neurological signs, but in microscopic evaluation showed no injury to justify these symptoms. In the heart it was possible to notice the presence of visible vascular abnormalities, such as disseminated intravascular coagulation, necrosis of the myocytes near these vessels, congestion and bleeding due to severe thrombocytopenia developed during infection. In the lung was noted pneumonia in most animals studied. The liver also appeared affected, but not directly by infection, but as a result of other harmful factors related to the disease. In all evaluated kidneys showed this glomerulonephritis. In all 16 animals can be noted splenomegaly. The mesenteric lymph node is not a very studied structure in animal CME, but you may notice a large plasma cell infiltrate. However, the vasculitis was responsible for much of the lesions, predominant being the plasma cell infiltrate

Predomina nas regiões mais quentes do planeta devido ao fato de seu hospedeiro intermediário, um artrópode, prevalecer nos locais de altas temperaturas. Em função da gravidade da enfermidade para os animais e ao potencial zoonótico da doença, estudos envolvendo as possíveis alterações renais são essenciais para o diagnóstico e prognóstico da doença. Neste ensaio, objetivou-se avaliar as proteínas séricas e urinárias de cães com erliquiose na fase subclínica, por meio da técnica de eletroforese em gel de poliagrilamida contendo dodecil sulfato de sódio (SDS-PAGE). Os animais foram devidamente distribuídos em grupo controle (GC), 18 cães saudáveis e grupo doente (GD), integrado por 17 cães acometidos por erliquiose subclínica, sendo que o diagnóstico da infecção foi confirmado ou excluído levando-se em conta a associação de exames clínicos, sorológicos e PCR. Os resultados mostraram que os cães na fase subclínica da erliquiose apresentaram alterações laboratoriais como, trombocitopenia, hiperglobulinemia com hipoalbuminemia compensatória e aumento de proteínas totais, além de anemia. A partir do traçado eletroforético sérico, concluiu-se que os cães infectados na fase subclínica apresentaram elevação na concentração de transferrina, IgG de cadeia pesada, haptoglobina, alfa 1-glicoproteína ácida e proteína de peso molecular 23 kDa. A análise do traçado eletroforético urinário dos animais experimentais, associada com o resultado da UPC, o qual revela proteinúria limítrofe nos indivíduos doentes, demonstraram que existem lesões renais, tanto em nível glomerular quanto tubular, em cães com erliquiose na fase subclínica, entretanto, mais estudos se fazem necessários para esclarecer e detalhar melhor as referidas lesões / Ehrlichiosis is a hemoparasitosis that affects around 20 to 30% of dogs treated at veterinary clinics in Brazil, which may lead the animal to death. It predominate in the warmer regions of planet because of its intermediate host, an arthropod, that lives in high temperature regions. Due to the severity of the disease to animals and its zoonotic potencial, studies involving the possibles renal disorders are essential for the diagnosis and patient's prognosis. In this trial aimed to evaluate serum and urinary proteins of dogs with ehrliquiosis in the subclinical stage, by electrophoresis in poliacrilamida gel containing sodium dodecyl sulfate (SDS-PAGE). The animals were divided into control group (CG), 18 health dogs and sick group (SG), the last one with 17 dogs with diagnosis of erlichiosis subclinical, and the diagnosis of infection was conformed or excluded by association of clinical exams, serological tests and PCR. The results showed that dogs on the subclinical stage of ehrlichiosis had laboratory changes as thrombocytopenia, hyperglobulinemia associated with compensatory hypoalbuminemia and increased total protein, and anemia. From the serum electrophoresis, it was concluded that the infected dogs in subclinical phase had increased concentration of transferrin, the heavy chain of IgG, haptoglobin, alpha 1-acid glycoprotein and protein molecular weight 23 kDa. The analysis of urinary electrophoretic trace of the experimental animals, the result associated with the UPC, which shows borderline proteinuria in diseased dogs, showed that there renal lesions, both as tubular glomerular level, in dogs with erliquiosis in the subclinical stage, however, more studies are needed to clarify and better detail these injuries
