Abstract

California Mastitis Test (CMT) and somatic cells count (SCC) were studied as auxiliary methods for diagnosis of the bovine subclinical mastitis in the identification of ill mammary quarters where Staphylococcus aureus and Corynebacterium were isolated later. CMT and SCC showed higher diagnostic sensitivity when S. aureus was the microorganism isolated from milk samples compared to the Corynebacterium (88.6% and 86.1% against 49.1% and 59.1%, respectively). The diagnostic efficiency of the tests were both higher when subclinical mastitis was caused by S. aureus, compared to the Corynebaterium (81.0% and 87.1% against 60.5% and 76.7%, respectively). CMT and SCC demonstrate a linear relationship in the mammary quarters where S. aureus was isolated. The same result was not exhibit when Corynebacterium spp was isolated.
