Streptococcus uberis and its ecology in the dairy cow


, : Streptococcus uberis and its ecology in the dairy cow. Diss. Abstr. int, State Univ., Ames, Iowa, 30B: 5164

A wide variety of biochemical and physiological tests were carried out on 168 strains of Str. uberis isolated from 24 cows, and 19 other streptococcal strains, in order to characterize the organism. Bac-teriophage activity was studied and the phage sensitivity of 147 strains tested wtih a view to identification of Str. uberis. Four phages, Nos. I, II, IV and XI were more active than the others. Of the 128 sensitive strains, 126 were lysed by one or more of these phages.
