To elucidate the relationship between the virulence of intracellular bacterium and its ability to induce 3'/8 T cells in the host during infection, we examined the differences in appearance of 3'/8 T cells in mice infected with Salmonella choleraesuis virulent strain RF-1 carrying a virulence plasmid of 50 kb, and with avirulent strain 31N-1 cured of the 50-kb plasmid. The number of 3'/8 T cell...

2. Nontyphoidal salmonellosis is caused by Salmonella species other than Salmonella Typhi and Salmonella Paratyphi. The epidemiology and prevention of typhoid fever have been reviewed in a separate SCEIFD Paper 1/2011 (“Epidemiology and Prevention of Typhoid Fever in Hong Kong”). Nontyphoidal salmonellosis is one of the leading foodborne illnesses and accounted for a considerable morbidity and ...

BACKGROUND Salmonella is a food- and water-borne pathogen that can be easily spread in a population, leading to the outbreak of salmonellosis that is caused by ingestion of mixed salads contaminated by the pathogen. Most cases occur in the late spring months and can be seen as single cases, clusters, or episodes. OBJECTIVE The aim of this study was to describe the incidence and epidemiologica...

The incidence of the most common foodborne outbreaks reported by European Food Safety Authority and Centre for Disease Prevention Control during years 2015–2019 is described. Campylobacter spp., Salmonella Listeria monocytogenes, Yersinia enterocolitica are investigated microorganisms, symptomatology, food categories responsible human disease, as well some prevention measures important informat...

Objective: Salmonellosis is a bacterial disease with a rising prevalence in the cattle industry. It is most common in dairy calves one to ten weeks of age. Salmonellosis has a serious economic impact on the cattle industry worldwide. Methods: In May 2013, a three months old male Holstein calf with the history of lateral recumbency was referred to veterinary hospital with severe depression, cach...

Salmonellosis is one of the most common infections of poultry and other host species including human. It causes food borne diseases in humans when eggs may get contaminated by horizontal or vertical contamination [1]. Salmonella have been known to cause illnesses for more than 100 years and are Gram negative bacilli belonging to the Family Enterobacteriaceae. Like most Enterobacteriaceae they a...

OBJECTIVE Travel-related enteric infections likely represent a large proportion of all enteric infections in British Columbia (BC). The objective of this study was to assess the proportion of enteric infections in BC reported in 2008 associated with international travel in order to understand trends in infections so that targeted interventions can be implemented. METHODS Travel information fo...

In the United States, swine salmonellosis is most often attributed to infections by Salmonellaserovar choleraesuis. As a host-adapted pathogen rarely found in nonswine sources, S. choleraesuis is thoughtto be spread primarily via horizontal transmission, with carrier animals playing an important role. Little hasbeen reported regarding infection of neonatal piglets, particularly rega...
