Preliminary Report on the Incidence of Laboratory-confirmed Clinical Salmonellosis in Northeast USA Dairy Herds

摘要

Salmonellosis in dairy cattle ranges from subclinical infections to serious illness. Many studies have assessed fecal shedding. The objective of our study was to determine the incidence of clinical salmonellosis in dairy animals in the northeastern United States. Veterinary clinics were enrolled in the study between February and September of 2004. Veterinarians enrolled farms in the study by submitting a one-page survey, including numbers of cattle in the herd.
