background and objectives: salmonella is an important food-borne pathogen in humans. strains of salmonella spp. that producing extended-spectrum β-lactamases have become a concern in medicine regarding both antimicrobial treatment and infection control program. the objective of this study was to describe the antibiotic susceptibility, esbl production and determining the prevalence of the bla ct...

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 purpose of this study was to survey infections with Salmonella spp. in poultry flocks in the vicinity of Tehran and to determine the most frequent serogroups and serotypes implicated. Twenty-eight samples of pullet, layer, and broiler flocks were randomly collected (n=1463), including freshly dropped feces from live birds or visceral organs from dead birds. In most flocks, 60 samples were t...
