Background and Objective: Salmonellosis is one of the most important zoonotic diseases; most of the infections caused by the consumption of contaminated food is caused by this bacterium. During the last decades, the resistance of Salmonella isolates to conventional antibiotics has increased, which is a global health problem. The objective of this study was to investigate Salmonella serotypes in...

Dry heat was used to inactivate Salmonella newington, Salmonella typhimurium, Salmonella anatum, Salmonella kentucky, Salmonella cubana, Salmonella seftenberg, Salmonella thompson, and Salmonella tennessee in corn flour at 10 and 15% moisture. The flour was spray inoculated at 10(5) Salmonella cells per g and then stored at 49 degrees C (120 degrees F); viable Salmonella cells were counted on T...

Forty-nine cell envelope proteins of Salmonella typhimurium SL1344 have been identified by microsequencing and assigned to a two-dimensional reference map. Ten of the sequenced proteins appear to be novel. Several others closely match currently hypothetical proteins or proteins found in other bacteria but not previously reported in salmonellae.

OBJECTIVES To detect the qnrA, qnrB and qnrS genes among Salmonella isolates received at the French National Reference Centre for Salmonella in Paris, France. METHODS Antibiotic susceptibility was determined by disc diffusion for 499 Salmonella isolates including 320 Salmonella Typhimurium, 100 Salmonella Enteritidis and 79 Salmonella Hadar collected in 2002. Amplification with specific prime...

Nontyphoidal Salmonella infections caused by antimicrobial-resistant (AMR) strains are of great public health concern. We compared the phenotypic and genotypic relationships among temporally and spatially related AMR Salmonella isolates (n=1058) representing several predominant serovars, including Salmonella Typhimurium, Salmonella Typhimurium var. 5-, Salmonella Derby, Salmonella Heidelberg, S...

Salmonella has been reported to be presence both in raw and processed foods worldwide. In this study, the prevalence, quantification and antibiotic susceptibility of Salmonella isolated from raw vegetables or locally known as ulam such as asiatic pennywort (Centella asiatica (L) Urb), water dropwort (Oenanthe javanica (Blume) DC), long bean (Vigna sinensis EndL), and winged bean (Psophocarpus t...

An R factor carrying tetracycline resistance, the transfer of which was observed in mating cultures at 25 but not at 37 C, was demonstrated in strains of Salmonella typhimurium isolated from calves.

It was demonstrated earlier in this laboratory that phage P22 induces a transient depression in the cellular transport processes of the host Salmonella typhimurium immediately after infection and that an effective injection process is enough to cause the depression. By using defective phage particles that contain host DNA instead of phage DNA for infection, it has been demonstrated that the inj...

Control of within-herd transmission of Salmonella is important for reducing the prevalence of this organism on pig farms and for preventing Salmonella-contamination of pork. At the farm level, understanding the within-herd transmission of Salmonella can lead to more effective control. Salmonella infection is dependent on the inoculation dose; hence, quantitative evaluation of Salmonella shed in...
