Abstract
The hypothesis that strains of
Staphylococcus aureus are more likely to be unique to a herd than common to several herds was tested. Herds (
n=28) from nine geographic areas of Korea, with elevated milk somatic cell counts (>500
000 cells/ml) were enrolled in this study. Mammary quarter milk samples were aseptically collected from all lactating cows (
n=616) with at least three functional quarters. Milk was cultured and
S. aureus isolates were typed using pulse field gel electrophoresis of DNA
SmaI digests. A total of 181 cows were identified as having
S. aureus intramammary infections. A total of 52 different types of
S. aureus were identified and 34 (65.4%) were associated with a single herd. A total of 18 types of
S. aureus were found in multiple herds; 14 types were found in two herds, and four types were found in three herds. Herds with 1, 2, 3, and more than 3 types, were: four (14.3%); eight (28.6%); nine (32.1%); and seven (25.0%). The data indicate that the majority of strains were found in one herd only, and more than 90% were found in two or less herds, suggesting that strains of
S. aureus are more likely to be restricted to a single herd, than found in multiple herds.
