The quantity of seafood imported and produced by domestic aquaculture farming has increased. Recently, it been reported that multidrug-resistant (MDR) Salmonella Typhimurium may be associated with seafood. However, information is limited to the antimicrobial resistance, virulence properties, genetic diversity S. recovered from This study investigated isolated catfish, shrimp, tilapia. A total 1...

Salmonella typhimurium induced massive uptake of extracellular fluid in epithelial cells in the form of macropinosomes. The appearance of macropinosomes in the infected cell was related to the induction of membrane ruffling during bacterial invasion. A noninvasive S. typhimurium invA mutant did not trigger such effects in the host cell. Similarly, S. typhimurium invA mutants that invaded via th...

Le sésame constitue le deuxième produit d’exportation agricole au Burkina Faso mais sa qualité n’est pas toujours satisfaisante à cause de la présence d’impuretés et parfois microorganismes pathogènes notamment les salmonelles. La présente étude a pour objectif d’évaluer prévalence des salmonelles dans ses produits dérivés. Au total, 107 échantillons dont 73 graines 34 dérivés (biscuits, croque...

Guano samples from 412 Brazilian bats were screened with real-time PCR for the virulence genes (eae, est, elt, stx1, stx2, ehxA, invA, bfpA, aggR) representing five intestinal pathotypes of Escherichia coli. From 82 pooled samples, 22% contained Escherichia coli DNA, and eae, est, bfpA, aggR were detected.

Etiological diagnosis of diarrheal diseases may be complicated by their multi-factorial nature. In addition, Escherichia coli strains present in the gut can occasionally harbor virulence genes (VGs) without causing disease, which complicates the assessment of their clinical significance in particular. The aim of this study was to detect and quantify nine VGs (stx1, stx2, eae, aggR, ehxA, invA, ...

background: salmonella typhimurium is one of the most important species of salmonella that is intracellular parasite and attacks host mucus membrane. these bacteria can cause gastroenteritis, and their main transmission route is water, poultry, meat, egg, and raw food. the aim of this study was to detect three virulence genes associated with s. typhimurium named inva, stm4497, and flic183 genes...
