Epidemiology and clinical aspects of bovine salmonellosis

Buret, Y.; Guillet, D.; Decante, F.

Over 2.5 years between 1995 and 1998, 57 outbreaks of salmonellosis were diagnosed by a bovine practice in France. Samples were collected daily during outbreaks and data were obtained on the time distribution, number of animals affected and concurrent diseases. Mean prevalance of salmonellosis during the 2.5 years was 18% and the monthly case incidence was 1.9. In the majority of cases, digestive symptoms were expressed clinically with an elevated prevalence of Salmonella typhimurium.
