A total of 1,013 isolates of Enterobacteriaceae were identified in parallel by the Repliscan (Cathra International, Ontario, Canada) and API 20E (Analytab Products, Plainview, N.Y.) systems. There was a 62% agreement at the genus level between the two systems. Of the 38% discrepant results, Repliscan classified 22% as "biochemical pattern not on file," 8% as a multiple-genus group which include...

A cross-sectional study was conducted to detect the presence of Salmonella spp., Candida albicans, Aspergillus spp., and antimicrobial residues in raw milk (n = 120) and processed cow milk (n = 20) from smallholder dairy farms from three sites in Zimbabwe. Culture and isolation of Salmonella spp., C. albicans, and Aspergillus spp. were performed using selective media, while antimicrobial residu...

Escherichia coli O157 and Salmonella spp. are among the leading causes of food-borne illness in the United Sates and bacteria have been isolated from numerous ruminant animal sources. The objective of this study was to assess the incidence of E. coli O157 and Salmonella spp. in white-tailed deer (Odocoileus virginianus) and livestock simultaneously grazing the same rangeland. Escherichia coli O...

The aim of this work was to detect the presence of Salmonella spp. in recreational aquatic environments in the Northeast of Argentina and to relate it with water and environmental parameters. Sixty eight samples of water from recreational aquatic environments in the provinces of Chaco and Corrientes, Argentina, were studied. Salmonellae were detected in 6 samples (8.8%). Salmonella spp. isolate...

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...

BACKGROUND Salmonella enterica serovar Typhi, as causative agent of typhoid fever, is one of the most important endemic pathogens. Non-typhoidal Salmonella serovars, including Typhimurium, Infantis, and Enteritidis are amongst the most prevalent serotypes worldwide and in developing areas such as Iran. The aim of this study was to apply a uniplex PCR for rapid detection of Salmonella spp., and ...

We describe a new chromogenic agar medium, ABC medium (alphabeta-chromogenic medium), which includes two substrates, 3, 4-cyclohexenoesculetin-beta-D-galactoside and 5-bromo-4-chloro-3-indolyl-alpha-D-galactopyranoside, to facilitate the selective isolation of Salmonella spp. This medium exploits the fact that Salmonella spp. may be distinguished from other members of the family Enterobacteriac...

conclusions due to the presence and potential hazard of e. coli o157:h7, l. monocytogenes, and salmonella spp. in meat samples, the detection of these pathogens in different kinds of meat is crucial to safeguard public health. results l. monocytogenes was detected in 2.8% of beef and buffalo samples and 4.3% of lamb samples. e. coli o157:h7 was detected in 2.8% of beef and 1.4% of buffalo sampl...
