Pigs were exposed to various levels of Salmonella enterica subsp. enterica serovar Typhimurium by either intranasal inoculation or by subjecting them to a contaminated environment. More than 10(3) salmonellae were required to induce acute Salmonella infection. These results indicate that intervention against acute Salmonella infection in lairage may be more readily achieved than previously thou...

A novel virus, designated Cygnet River virus (CyRV), was isolated in embryonated eggs from Muscovy ducks in South Australia. CyRV morphologically resembles arenaviruses; however, sequencing identified CyRV as an orthomyxovirus. The high mortality rate among ducks co-infected with salmonellae suggests that CyRV may be pathogenic, either alone or in concert with other infections.

The quantification of microorganisms present in food samples is an important step to assess the risk to consumers. The number of salmonellae in 20 positive samples of minced pork was determined by the Most Probable Number method. Counts ranging between <3 and 240 cfu.g were found in the analyzed samples.

Salmonellae are a significant cause of morbidity and mortality globally. Here, we report the first complete genome sequence for Salmonella enterica subsp. enterica serovar Java strain NCTC5706. This strain is of historical significance, having been isolated in the pre-antibiotic era and was deposited into the National Collection of Type Cultures in 1939.

Ten isolates of Salmonella infantis (serologically typed) were found in litter and runoff collected from two experimental feedlots near the Kansas State University campus. Pathogenic implications are discussed relative to recreation water sites. Agricultural runoff maybe a source of viable salmonellae.

This study was conducted to determine the prevalence of Salmonellae contamination of chicken carcasses in slaughterhouses in central Iran (Yazd province). 435 samples were obtained from liver, breast— before and after chilling—and bacteriological and serological examinations were done. The results showed that the rate of contamination of liver, breast meat—before and after chiller—were 8.1, 18....
