摘要：

A total of 166 samples of secretions collected from Danish heifers suffering from clinically diagnosed summer mastitis were examined bacteriologically. One hundred and sixty three samples yielded positive findings whereas no growth was obtained from 3 specimens. The majority of samples revealed a mixed flora in which the predominant components were Actinomyces pyogenes, Peptostreptococcus indolicus, a microaerophilic coccus (Stuart-Schwan coccus), Fusobacterium necrophorum, Bacteriodes melaninogenicus and Streptococcus dysgalactiae. Pure cultures were recovered in only 7% of cases. P. indolicus was isolated from 87% of the cases, a microaerophilic coccus from 84%, A. pyogenes from 72%, Fusobacterium necrophorum from 52%, Str. dysgalactiae from 37%, B. melaninogenicus from 33% and various unidentified obligate anaerobic Gram-negative rods from 31%. The results confirm the complex bacterial aetiology of summer mastitis. © 1990.
