Abstract: Enterotoxigenic staphylococci (ES) were detected in 363 (34.4%) out of 1,056 coagulase-positive isolates obtained from California Mastitis Test-positive milk from 708 cows on 168 farms scattered throughout Japan. The ES produced enterotoxins C (54.3%), A (31.1%), D (27.0%) and B (10.7%) either alone or together. None produced enterotoxin E. The ES were isolated from 34.0% of the mammary quarter-milk samples. Of the enterotoxigenic isolates, 38.6% were typable by the basic set for typing bovine staphylococci, while 62.3% of the nonenterotoxigenic isolates were typable. Almost all of the enterotoxin A- and D-producing isolates belonged to phage groups III or I/III. Several repeated examinations of the same cows showed that the ES persisted in the mammary glands of the same cow for at least 8 months and that it was transmitted to other cows of the same farm. These results indicated that staphylococcal infections of the bovine mammary glands represent a significant reservoir of ES.
