Abstract

Double antibody sandwich ELISA (DAS-ELISA) was developed for detection of staphylococcal antigens in milk samples from sub-clinical mastitis cases of cows. Out of 279 quarter milk samples from 72 apparently healthy lactating crossbred cows screened for staphylococcal mastitis, 41.22% and 12.90% milk samples were detected for Staphylococcus. aureus and S. epidermidis antigens by DAS-ELISA specific for S. aureus and S. epidermidis, respectively. In cultural examination, 42.29% were found positive for sub-clinical mastitis. DAS-ELISA was found rapid, cheaper, sensitive, specific and less cumbersome as compared to cultural examination. DAS-ELISA system specific for S. aureus was found to be used for screening the herd for both S. aureus and S. epidermidis mastitis whereas DAS-ELISA specific for S. epidermidis was useful assay for detection of S. epidermidis mastitis only.
