<p>The aim of this research was to identify the occurrence of pathogens causing subclinical mastitis in grade B milk farms of the Jaguapitã county, state of Paraná, Brazil. California Mastitis Test (CMT) were carried out in 400 milk samples from 100 animals and 157 teats from 55 animals (55%) were positive, showed score two or higher to CMT. When these 157 positive samples to CMT were transported for bacterial culture in blood agar, 25.48% (40/157) samples showed no bacterial growth or more than two types of bacterial colonies grew, 28.03% (44/157) were Coagulase-negative staphylococci (CNS), 8.28% (13/157) were <em>Streptococcus uberis</em>, 7.64% (12/157) were <em>Staphylococcus aureus</em>, 7.64% (12/157) were <em>Corynebacterium </em>spp, 7.01% (11/157) were <em>Staphylococcus intermedius</em>, 4.46% (7/157) were <em>Staphylococcus hyicus</em>, 3.82% (6/157) were <em>Bacillus </em>spp., 2.55% (4/157) were <em>Streptococcus dysgalacteae</em>, Enterobacteria and Yeasts. We conclude that CNS is the most relevant subclinical mastitis causative agent.</p><p><strong> </strong></p>
