Abstract: Bovine mastitis is an important and a persistent infection in the buffalo population producing high economic losses. The study was conducted on 500 housed dairy buffaloes in El-Bahiera Governorate, Egypt. The purposes of study were to determine incidence of mastitis, bacterial isolates from mastitic milk, clinical findings of clinical mastitic buffaloes, antimicrobial sensitivity on bacterial isolates, monthly incidence of mastitis post calving and cure rate after different treatments of E. coli mastitis post calving. Incidence of subclinical mastitis more prevalent than clinical mastitis in housed buffaloes in percentages 18.5% and 9% respectively. S. aureus, E. coli, St agalactia and St. dysgalactia were the most common isolates in clinical mastitis. E. coli, S. aureus, C.N.S, Pseudomonas, St agalactia, and St. dysgalactia were the most common isolates in subclinical mastitis. Mixed infection observed in our study in which S. aureus and E. coli common cause in clinical mastitis 24.4% and S. aureus and C.N.S common cause in subclinical mastitis 18.9%. Clinical finding of clinical mastitic buffalo’s variable according to causative agent in which S. aureus and E. coli the most sever cause of mastitis in the form of fatal peracute and acute with systemic reaction. 1st and 2nd month post calving were the highest incidence of mastitis in percentages 51.1% and 17.7% in clinical mastitis respectively, and 38.1% and 19.8% in subclinical mastitis; respectively. Amoxicillin and clauvilinic acid, Cefotaxime and Enrofloxacin were found most effective drugs against all isolates. The best results obtained in Forfenicol and ceftiofur groups in treatment of E. coli mastitis by cure rate 90%, only one case return to chronic with no case fatality. In Enrofloxacin group, cure rate 70%, only one case return to chronic with 20% Case fatality. In panterramycin group, cure rate 20%, three cases return to chronic with 50% Case fatality.
