Abstract
Among 190 milk samples confirmed positive for
bovine mastitis by California mastitis test,
Somatic cell count and White side test. Among 190
samples, 138 (72.63 %) samples. Staphylococcus
aureus (27.37%) was found to be the most prevalent
organism followed by coagulase negative
Staphylococcus spp. (12.63%), E. coli. (08.95%),
Pseudomonas spp. (07.89%), Streptococcus spp.
(05.79%), mixed bacterial infection (04.74%),
yeast (03.15%), Klebsiella spp. (01.57%) and
Bacillus spp. (00.52%). Further, the incidence of
bovine mastitis was recorded under different
climatic conditions, which was found to be highest
in winter followed by summer and least in rainy
season. Additionally, it was observed that Gram
positive organisms were more common cause of
bovine mastitis than Gram negative and
Staphylococcus aureus was most common isolate in
all the seasons. Incidence of bovine mastitis has
been also recorded under different climatic
conditions. However, Streptococcus spp. showed a
significant rise in incidence during summer. Our
results revealed that there was a definite impact
of seasonal variation on incidence of bovine
mastitis and the microbe associated with it.
