| Summary: | Mastitis in dairy cows is an economically important disease because it makes
up 38% of all diseases that occur in intensive cattle breeding. Mastitis
affects milk production, either temporarily or permanently, depending on the
course of infection and type of pathogen agent. Regular and timely therapy of
mastitis based on the application antimicrobials, apart from prophylaxis, is
very important for good health of breeding stock. This paper presents the
case of repeated mastitis in a cow, Holstein-Friesian breed, 5 years old,
which did not respond to antibiotic therapy. Milk samples from each separate
quarter of the udder were collected under aseptic conditions and sent to the
laboratory for further bacteriological tests, for isolation and
identification of pathogens, as well as to test pathogen resistance to some
antibiotics. On the basis of bacteriological examinations, there was
confirmed the presence of Streptococcus dysgalactiae, which showed
sensitivity to ampicillin, cloxacillin and augmentin, intermediate resistance
to tetracycline and resistance to kotrimeksazol.(cotrimoxazole-proveriti)
