A total of 518 fecal samples collected from 183 apparently healthy cattle, 180 pigs and 155 broilers throughout Japan in 1999 were examined to determine the prevalence and antimicrobial susceptibility of Salmonella. The isolation rates were 36.1% in broilers, 2.8% in pigs and 0.5% in cattle. S. enterica Infantis was the most frequent isolate, found in 22.6% of broiler fecal samples. Higher resi...

Sea foods are prone to bacterial contamination and could cause health risk to consumers. The present work aimed to study the occurrence of Salmonella and Vibrio in some seafood from different markets in Alexandria. The study was carried out on 150 seafood samples (shrimp, oyster (Gandofli) and mussel (Om El Kholoul)). For detection of Salmonella; samples were cultured on CHROM agar Salmonella P...

Aims: We aimed to compare Salmonella isolates from different sources using molecular and phenotypic methods, targeting better possibility of understanding the epidemiology of this organism in the Greek context with emphasis in municipal wastewater. Materials and Methods: In this study, we used pulsed field gel electrophoresis (PFGE) in combination with antimicrobial susceptibility testing to an...

The antimicrobial susceptibility profiles of Salmonella spp. isolated from livestock production systems in Sicily were determined. antibiotic sensitivity and broad-spectrum beta-lactamase strains assessed by detecting β-lactamases blaCTX-M IV, TEM, OXA SHV, blaCMY II, CTX-M I, DHA. In total, 93.3% showed multi-drug resistance (MDR). A total seven serotypes (i.e., Infantis, S. Typhimurium (monop...

Salmonella is one of the most common causes of food poisoning in the European Union and the United States of America. Free-living birds are known as a reservoir for the different serovars of Salmonella, including S. Typhimurium, S. Enteritidis, S. Infantis, S. Newport and S. Hadar, which may play an important role in the epidemiology of salmonellosis in farm animals, particularly poultry. Also,...

A multiplex PCR-based assay was developed for detection of Salmonella typhi and identification of other salmonella serotypes. Three primer-sets were selected from different genomic sequences, malo2F/malo2-Ra primers from invasion gene, Parat-s/Parat-as as well as tyv-s/tyv-as primers from Oantigen gene cluster of the genus Salmonella. This method differentiated Salmonella spp., based on size an...

A total of 126 Salmonella spp. isolates from pigs belonging to 13 serotypes (Typhimurium, Derby, Infantis, Enteritidis, Agona, Kaapstad, London, Montevideo, Bredeney, Give, Oritamerin, Schwarzengrund and Tennessee) were tested for sensitivity to 14 antibiotics. Resistance to 1–8 antibiotics was demonstrated in 64 isolates (59.8%), classified into seven serotypes with the most frequent being Sal...
