Popis: | Mastitis, caused by multifactorial etiopathological factors, is one of the costliest disease of dairy animals across the globe. The study was conducted for a period of more than 1 year i.e. from February 2015 to February 2016. For the epidemiological study 550 lactating cattle were screened by modified California mastitis test (MCMT). Clinical examination of animals and their udder/milk and phenotypic characterization of Staphylococcus spp. was carried out. The overall occurrence of Staphylococcal SCM was reported to be 16.36% (90/550) animal wise and 6.07% (127/2092) quarter wise as identified on the basis of colony morphology, characteristic colour changes on Mannitol salt agar, positive catalase test, haemolysis pattern on blood agar and DNase activity on DNase agar. Thirty one isolates were found coagulase positive as revealed by coagulase test and 96 were found to be coagulase negative Staphylococci (CNS). The occurrence was highest in right hind quarter (8.77%), in age group of 5–7 years (23.77%). in 5th parity (25.64%) and in early lactation (31.64%) period. Occurrence was also reported higher in monsoon and post monsoon. |
