RESUMEN
Salmonella Typhimurium was isolated from a faecal sample from a cow in a Swedish dairy herd after calving. When investigations were undertaken in the herd, Salmonella Thompson was isolated from heifers on a separate pasture, and when these heifers were brought into the herd S Thompson spread rapidly. Control strategies managed to rid the herd of the S Typhimurium infection and the prevalence of S Thompson was at first substantially reduced. There was a rapid increase in its prevalence when the animals were let out to pasture and this development eventually led to the depopulation of the entire herd.
