Mastitis is an economically important bacterial disease of the dairy animals. 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.
