The study was conducted to identify the prevalence of
Staphylococcal mastitis in bovines from Namakkal region and the therapeutic
response of antibiotics to Staphylococci by assessing the antibiotic
sensitivity pattern in clinical settings. Milk samples (n= 241) were collected
from clinical and subclinical mastitic cows which were brought to teaching
veterinary clinical complex (TVCC), Veterinary College and Research Institute
(VC&RI), Namakkal, Tamil Nadu and subjected to isolation on mannitol salt agar,
Gram’s staining and confirmation by polymerase chain reaction (PCR) using
specific primers. The prevalence of Staphylococcus aureus at cow level was 61.5
and 57.4 per cent in clinical and subclinical cases, respectively, and at
quarter level was 58.8 and 57.4 per cent in the clinical and subclinical cases,
respectively. Antibiotic sensitivity pattern revealed a high sensitivity to
enrofloxacin (100.0%) and a high resistance to methicillin (100.0%) by S.
aureus isolates, and multidrug resistance by S. aureus isolates was also
observed. Though enrofloxacin was found to be very effective in therapeutic
management of most staphylococcal mastitis cases, antibiogram of milk sample
from each mastitis cow is essential to monitor the development of resistance of
Staphylococcus aureus in clinical or subclinical mastitis to the range of
antibiotics commonly used. This would help in the early treatment of mastitis
with sensitive antibiotics and prevent the case entering into the chronic
stage, failure of treatment and loss of the value of cow.
