Diagnosis of subclinical bubaline mastitis by various tests [data are presented as number (%) of quarter milk samples].

SCC = somatic cell count; EC = electrical conductivity; CMT = California mastitis test; BTB–bromothymol blue; NAGase = N-acetyl-β-D-glucosaminidase; NA = not applicable Cut-off values used for declaring positivity were 2 x 105 / mL of milk for SCC, ≥ 3.8 mS / cm for EC and corrected OD405 value of 0.09 for NAGase test, as described in materials and methods. CMT and BTB are qualitative tests and hence do not have cut-offs. Diagnosis of subclinical bubaline mastitis by various tests [data are presented as number (%) of quarter milk samples].
