During the study period (i.e., June to October, 2013) 200 animals, including
lactating yak, mithun and local cattle were screened for Intramammary Infection
(IMI) caused by major pathogens in organized and unorganized farms in North
Eastern Hill (NEH) region, Dirang, Arunachal Pradesh. Out of 200 animals screened
for the status of IMI, 19 yaks were found positive for mastitis. The major pathogens
isolated and characterized from positive milk samples categorized in four types
of bacteria and amongst them majority were coagulase negative Staphylococcus
aureus (47.36%) which was the most prevalent pathogen in the region, followed
by E. coli (26.3%), coagulase positive Staphylococcus aureus (15.78%)
and Streptococcus agalactiae (10.5%). The antibacterial sensitivity pattern
revealed maximum sensitivity for ceftriaxone (94.74%) and minimum for ampicillin
(15.79%). The resistance pattern showed coagulase negative Staphylococcus
aureus (CNS) was most resistant bacteria against ampicillin and amoxicillin,
where the antibacterial zone depicted to be 7 and 9 mm, respectively. The present
study reported, the general sensitivity and resistance pattern of the antibiotic
against the major pathogens isolated from yak mastitis milk samples from NEH
region of Arunachal Pradesh.]]>Albenzio, M., L. Taibi, A. Muscio and A. Sevi,200243219226Awandkar, S.P., N.V. Khode, V.M. Sardar and M.S. Mendhe,20094117122Balows, A., H. Truper, M. Dvorkin, W.
