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...

The InvA tool supports the deductive verification of safety properties of infinite-state concurrent systems. Given a concurrent system specified as a rewrite theory and a safety formula to be verified, InvA reduces such a formula to inductive properties of the underlying equational theory by means of the application of a few inference rules. Through the combination of various techniques such as...

Salmonella spp. are zoonotic enteric bacteria able to infect humans, livestock and wildlife. The aim of this study was to investigate the prevalence of Salmonella (spp.) and to determine antibiotic susceptibility, serogrouping and presence of invA gene (Salmonella Invasion Gene A) in the detected strains in wild captive herbivores in Iran. The fecal samples of 103 animals from 8 different speci...

The aim of this study was to evaluate the microbiological quality Minas fresh cheese commercialized in Federal District, Brazil. For this, 20 samples industrialized cheeses were collected supermarkets and artisanal public food markets. analyzes performed total count bacteria, determination coliforms, S. aureus identification Salmonella spp. (InvA gene) (SeC gene). results showed that 26 (65%) u...

This study was performed to investigate the prevalence of Salmonella spp. in 100 free freshwater common carp samples using the classic culture technique. For the confirmation of the isolates at molecular levels, the invA gene was detected. Serotyping of the isolates was also detected. The presence of invA, class 1 (Cls1) integrons, and integrase (Int1) genes was demonstrated by PCR assay; and th...

Tilapia (Oreochromis niloticus) is the most cultivated and consumed freshwater fish in Brazil. The present study aimed to evaluate microbiological quality of ice fresh tilapia samples commercialized Federal District. were tested for counts mesophilic psychrotrophic bacteria, determination total thermotolerant coliforms, Staphylococcus aureus presence Salmonella. Ice analyzed coliforms Escherich...

API 20E and invA PCR were evaluated for the identification of Salmonella enterica isolates from swine farms. API 20E had the highest agreement with other tests at the 99.9% likelihood level. Both tests had 100% sensitivity and 96% specificity compared to 16S rRNA sequencing. Compared to serotyping, both tests had 96% sensitivity; specificity was 86% for API 20E and 79% for invA PCR.
