An investigation was carried out to identify the streptococci species isolated from clinical cases of bovine
mastitis in Kwara, Kaduna and Oyo States of Nigeria. Milk samples from 200 clinically mastitic udders were bacteriological
studied. A total of 130 streptococci isolate belonging to six species of streptococci, namely
S. uberis
,
S. agalactiae
,
S.
dysgalactiae
,
S. epidemicus
,
S. bovis
,
S. equinus
were recovered from the milk examined.

Streptococcus agalactiae (24.6%),
Streptococcus dysgalactiae (12.3%)
Streptococcus zoopidemicus (3.9%)
