Flora bacteriana e citoquínas pró-inflamatórias no trato digestório exclusivo após cirurgia de derivação em Y de Roux para obesidade mórbida / Microbial flora and proinflammatory cytokines in excluded digestive tract after Roux en-Y gastric bypass for morbid obesityIshida, Robson Kiyoshi 10 October 2007 (has links)
Introdução: Em estudo prospectivo, os efeitos da gastroplastia redutora com reconstrução em Y de Roux sobre a flora bacteriana e produção de citoquinas nas câmaras gástricas proximal e excluída foram estudados. Métodos: pacientes bariátricos (n=37) foram submetidos à avaliação endoscópica em ambos reservatórios gástricos,7,3+-1,4 anos após a gastroplastia. Idade foi de 42,4+-9,9 anos (70,2% sexo feminino), IMC pré-operatório de 53,5+-10,6, e IMC atual de 32,6+-7,8kg/m2. TNFalfa e TGF-beta foram medidos pelo método ELISA em biópsias da mucosa gástrica., assim como cultura quantitativa da secreção gástrica, com pH gástrico e teste respiratório lactulose/hidrogênio.Resultados: Nenhum dos pacientes apresentou queixas sugestivas de supercrescimento bacteriano gastrointestinal. Todavia, contagens elevadas de bactérias e fungos foram identificadas nas duas câmaras, principalmente no estômago proximal. Gram-positivos representaram a maioria dos isolados. O pH foi neutro na câmara proximal, enquanto que também na câmara distal nem sempre conservou-se em níveis esperados. Conclusões: 1)Produção elevadas de TNF-alfa e TGF-beta, com a colonização de aeróbios, anaeróbios e fungos em ambas câmaras gástricas foram identificadas; 2)O pH gástrico como a contagem bacteriana foram maiores no estômago proximal funcionante; 3)Teste respiratório foi positivo para supercrescimento bacteriano em 40,5% dos pacientes,entretanto não foram identificadas manifestações clínicas de supercrescimento bacteriano gastrointestinal. / Background: In a prospective study, the effect of Roux-en-Y gastric bypass (RYGBP) on bacterial flora and cytokines production in the used (proximal pouch) and unused (large bypassed) gastric chamber was analysed. Methods: Bariatric subjects (n=37) were submitted to endoscopic examination of both gastric reservoirs, 7.3 ± 1.4 years after RYGBP. Age was 42.4 ± 9.9 years (70.2% females), preoperative BMI was 53.5 ± 10.6, and current BMI was 32.6 ± 7.8 kg/m2.TNF-alpha and TGF-beta were meausured by enzyme-linked immunosorbent assay (ELISA) from gastric mucosal biopsies. Quantitative culture of gastric secretion along with gastric pH and actulose/hydrogen breath test were also investigated.Results: None of the subjects displayed complaints suggestive of GI bacterial overgrowth. Elevated counts of bacteria and fungi were identified in both chambers, mostly in the proximal stomach. Gram-positives represented the majority of the isolates. Gastric pH was neutral in the proximal pouch, whereas the distal chamber mostly but not always onserved the expected acidity. Conclusions: 1)Increased TNF-alpha and TGFbeta production, as aerobes, anaerobes and fungi colonization of both gastric chambers was detected; 2) Gastric pH as well as bacterial count was higher in the functioning proximal stomach; 3) Breath test was positive for bacterial overgrowth in 40.5% of the subjects, however clinical manifestation of GI bacterial overgrowth were not demonstrated

Floae : En utforskning av vaginal bakterieflora genom flytningar // Exploring vaginal bacterial flora through dischargeEnetjärn, My January 2022 (has links)
This project aims towards offering people with vulva an insight in their vaginal bacterial flora through vaginal discharge. Together with users, experts and collaboration partners, a problem space is defined. There are tabooin the society concerning how we relateto female genitalia which creates issues regarding shame and obstacles in seeking medical care when its needed. This is what the project hopes to contribute a small change to. Throughout this project process there is a sense of working together and creating together. The result is a vaginal discharge tracking device that offers peoplea visualization of their discharge in theform of colored light. The aim is to bring the conversation of vulvae, vaginal discharge and vaginal problems to a tangible space in order to normalize and actively work against shame connected to female genitalia. The concept also aims to enncourage people to be more open to talking to other people about the subject and seek medical care when needed. / Det här projektet är riktat mot att erbjuda personer med vulva insyn i sin vaginala bakterieflora genom flytningar. Tillsammans med användare, experter inom området och samarbetspartner, har en problemfromulering definierats. I samhället vi lever i råder mycket tabu kring hur vi relaterar till feminin intimbiologi vilket skapar problem i form av skam och hindrar personer med vulva frånatt söka vård då de behöver det. Detta är vad projektet hoppas kunna bidra med förändring till. Genom hela projektprocessen har fokus varit på gemenskap, att arbeta och skapa tillsammans. Resultatet är en produkt för att dokumentera och följa sina vaginala flytningar, som erbjuder personer med vulva en visualisering av flytningar i form av ljus. Syftet är att ta konversationen rörande underlivet, flytningar och vaginala problem till ett fysiskt utrymme för att normalisera och aktivt arbeta emot skam kopplat till kvinnliga könsorganet. Konceptet är också riktat åt att uppmuntra personer med vulva att vara mer öppna om att prata med andra om sitt underliv och att söka vård då de behöver det.

Étude de la flore bactérienne et de sa résistance aux antibiotiques des produits de la pêche et de l'aquaculture / Antibiotic resistance study of bacterial flora isolated from seafood productsBriet, Arnaud 11 December 2018 (has links)
La résistance aux antibiotiques est un enjeu de santé publique mondiale. L'alimentation est une des voies de contamination des bactéries résistantes aux antibiotiques entre l'environnement et l'Homme. Toutefois, les données concernant les bactéries résistantes aux antibiotiques dans les produits aquatiques sont rares. L'objectif de ces travaux a été d'étudier la flore bactérienne et sa résistance aux antibiotiques dans les produits de la pêche et de l'aquaculture. Dans un premier temps, la flore bactérienne mésophile cultivable a été isolée de 9 matrices différentes puis identifiée par la technique MALDI-TOF et/ou du séquençage de différents gènes de ménage. Au final, 1882 isolats bactériens ont été obtenus, et 150 espèces et 57 genres bactériens ont été identifiés. Dans un deuxième temps, nous avons étudié la résistance aux antibiotiques des genres bactériens les plus fréquemment isolés de ces produits. La résistance aux antibiotiques des genres Enterococcus, Staphylococcus, Exiguobacterium, Pseudomonas, Vibrio et Proteus a donc été étudiée. Au total, 46% des isolats étaient résistants aux antibiotiques et 3% étaient multi-résistants. Les crevettes étaient le produit dans lequel le plus de souches résistantes aux antibiotiques ont été identifiée. Et dans un troisième temps, la résistance aux antibiotiques d'une collection de souche de Vibrio parahaemolyticus, espèce bactérienne pathogène alimentaire pour l'homme, a été étudiée. Concernant V. parahaemolyticus, 15% des souches étaient résistantes et 3% des souches étaient multi-résistantes. Une souche, 16-B3PA-006, isolées de crevettes importées d'Asie du Sud-Est produisait une carbapénèmase NDM-1 et était résistante à 5 classes d'antibiotiques. / Antimicrobial resistance is a threat to global public health. Human can be contaminated by antibiotic resistant bacteria through food. However, data on antimicrobial resistant bacteria in seafood are scarce. The aim of this thesis was to study seafood bacterial flora and its antimicrobial resistance. First, mesophilic flora was obtained from 9 matrixes and MALDI-TOF and housekeeping genes sequencing technics were used to identify isolates. Antimicrobial resistance of most frequently bacteria were tested. In total, 1882 isolates were obtained and 150 bacterial species and 57 genera were identified. Enterococcus, Staphylococcus, Exiguobacterium, Pseudomonas, Vibrio and Proteus were most frequently isolated and their antimicrobial resistance was studied. Antibiotic resistant bacteria accounted for 46% of isolates and multidrug resistant bacteria accounted for 3% of isolates. Antimicrobial resistant bacteria were mostly isolated from shrimps. On a side study, antimicrobial resistance of a V.parahaemolyticus strain collection isolated from seafood was characterized. Antimicrobial resistant strains accounted for 15% and multi-drug resistant bacteria accounted for 3%. A NDM-1-producing multidrug resistant strain, 16-B3PA-006 was identified from shrimps imported from South-East Asia.
