| This study aimed at evaluating the bacteriological effects of the treatment of sheep meat contaminated with total coliforms, coliforms at 45 °C and Salmonella spp. by using irradiation at doses of 3 kGy and 5 kGy. Thirty sheep meat samples were collected from animals located in Rio de Janeiro State, Brazil, and then grouped in three lots including 10 samples: non-irradiated (control); irradiated with 3 kGy; and irradiated with 5 kGy. Exposure to gamma radiation in a 137Cs source-driven irradiating facility was perfomed at the Nuclear Defense Section of the Brazilian Army Technological Center (CTEx) in Rio de Janeiro. The samples were kept under freezing temperature (-18 °C) until the analyses, which occurred in two and four months after irradiation. The... |

| The gastroenteritis incidence caused by Salmonella Hadar has increased over the last decades worldwide. The uncontrolled use of antimicrobials for treating human patients and veterinary field contributes to increase the multidrug resistance of this serovar. In the present investigation, a total of 179 S. Hadar isolates from different sources of foodchain in Brazil were phage typed and analyzed for their antimicrobial resistance profile. The main S. Hadar phage types isolated were PT 38, PT 39, PT 40, PT 11, PT 34, PT 1 and PT 22. Others phage types as PT 13, PT 19, PT 21, PT 23, PT 31, PT 33 and PT 37 were obtained in low percentages. A total of 35,7% S. Hadar strains were resistant to two or more antimicrobials drugs. Furthermore, no resistance to third... |

| Salmonella Typhimurium has become a widespread cause of salmonellosis among humans and animals worldwide. In Brazil, Salmonella Typhimurium (STM) is one of the most prevalent serovars isolated from food for human consumption. The uncontrolled sale and use of antimicrobials in agriculture and for treating human patients contributes to increase multidrug resistance of this serovar. In the present study, a total of 278 STM isolates from different sources and regions of Brazil over the period 1999 to 2004 were phage typed and analyzed for their antimicrobial resistance profile at Laboratory of Enterobacteria, Oswaldo Cruz Institute, FIOCRUZ. The main STM phage types isolated were DT 193 (64.3%), DT 19 (17.4%) and DT 18 (4%). Others phage types as DT 10 (2%),... |

| Abstract The illegal wildlife trade may increase the risk of infectious disease transmission, and it may not only cause disease outbreaks in humans but also threaten livestock, native wild populations, and ecosystems' health. Bird species may act as carriers in the transmission of enteric pathogens. However, epidemiological studies on zoonotic bacteria in wild birds are rare in Brazil. From March 2011 to March 2012, we investigated the frequency of Enterobacteriaceae in cloacal swab samples from 109 birds of the passerine and Psittacidae families. These birds were recovered from illegal trade in Rio de Janeiro, Brazil, and sent to a rehabilitation center. Gram-negative bacteria were isolated from 86 wild birds (78.9%). A mean (±SD) of 1.68 (±1.30)... |
