The mycotoxin T-2 toxin and Salmonella Typhimurium infections pose a significant threat to human and animal health. Interactions between both agents may result in a different outcome of the infection. Therefore, the aim of the presented study was to investigate the effects of low and relevant concentrations of T-2 toxin on the course of a Salmonella Typhimurium infection in pigs. We showed that...

the purpose of this study was to elucidate some factors affecting the growth of salmonella typhimurium. these factors included carum copticum essential oil (0%, 0.015%, 0.03% and 0.06%), temperature (25 ˚c and 35 ˚c), ph (5, 6 and 7) and inoculum size (103 and 105  cfu ml-1). brain heart infusion broth was used as the growth medium. there were 48 treatment combinations and the experiment was ca...

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...

waterpipe smoking has become a global youth trend especially in the middle east countries and iran . the aim of this study was to determine the mutagenic effects of three most popular flavored tobaccos by four different salmonella typhimurium strains and compare the possible mutagenic effects of the test samples. ames mutagenicity assessment was conducted according to the oecd guideline using t...

background and objectives : economic constraint of diseases arising from salmonella typhimurium causes the study of this zoonotic organism more important. most studies on identification and characterization of s. typhimurium are conducted at dna level. flagellin genes (flic and fljb genes encoding phase-1 and phase-2 flagella, respectively) are useful as a model system for studying genetic diff...

background and objective : salmonellosis can be acquired through consumption of infected raw or undercooked eggs. the aim of this study was isolation and identification of salmonella spp from the eggshells and the egg contents samples of tabriz retails. methods : a total number of 150 samples of eggs were analyzed for the presence of salmonella spp. using conventional culture method and multipl...

Salmonella enterica is considered as one of the major pathogens in public health, worldwide. Diseases caused by Salmonella enterica serovars are especially prevalent in developing countries. It is one of the emerging pathogen in food-borne diseases, which is often found in contaminated chicken eggs. The aim of this study was to apply a PCR–RFLP method using Sau3AI and HhaI restriction endonucle...

Aim: To clone the Salmonella Typhimurium protein L-isoaspartyl O-methyl transferase (PIMT) enzyme and to analyze the sequence with PIMT gene of other pathogenic serovars of Salmonella. Materials and Methods: Salmonella Typhimurium strain E-2375 was procured from the National Salmonella Center, IVRI. The genomic DNA was isolated from Salmonella Typhimurium. Polymerase chain reaction (PCR) was ca...

Control of foodborne Salmonella within the farm-retail continuum is a complex issue since over 2500 serovars of Salmonella exist, the host range of Salmonella spp. varies greatly, and Salmonella is environmentally ubiquitous. To identify Salmonella enterica serovar Typhimurium (Salmonella Typhimurium) genes important for pathogen survival, our research group previously screened a signature-tagg...
