Genetic changes alter pathogenicity and zoonotic potential of Salmonella Typhimurium
Two closely related variants of Salmonella Typhimurium, a major cause of gastroenteritis worldwide, have significantly different effects on pig health, a study has found. The two variants, U288 and ST34, are particularly dominant in pigs and differed in colonisation of the intestine and surrounding tissues and the severity of disease they produced, scientists from the […]
Toxin promotes cattle-to-cattle transmission of E. coli O157
Shiga toxin subtype 2a (Stx2a) may play a key role in promoting the colonization and transmission of Escherichia coli O157 strains in cattle, according to a study published in PLOS Pathogens by Tom McNeilly of the Moredun Research Institute, David Gally of the University of Edinburgh, and colleagues. As these bacteria evolve ways to increase the […]
EU report on trends and sources of zoonoses
There were only minor fluctuations in reported cases of three main zoonotic diseases in the EU in 2017 compared to 2016. The number of reported cases of salmonellosis and campylobacteriosis has remained stable over the past five years, although listeriosis continues to rise. After several years of decline, salmonellosis cases in the EU have flattened […]
