Sažetak
This paper presents our observations during the second outbreak of bovine mastitis in Croatia. On a farm with approximately 700 dairy cows in different stages of lactation a significant increase in severe clinical mastitis cases resistant to antibiotic therapy was observed. The animals were of Friesian Holstein breed and some had been purchased from Western Europe. The acute form of mastitis was characterised by a rapid decrease in milk production, and a rapid spread of infection from affected to adjacent quarters. The animals were unsuccessfully treated with different antibiotics for several months. Combinations of tetracycline, neomycin and bacitracin ; penicillin G, dihydrostreptomycin, novobiocin and neomycin ; clavulanic acid-amoxicillin, cephalosporines ; and lincomycin were used. To investigate a possible role of mycoplasma as a causative agent of a large number of mastitis cases, 421 udder secretions were microbiologically examined. Mycoplasma colonies of typical appearance were cultured from 77 milk samples. Mycoplasmas were identified directly from milk samples by antigen capture ELISA test and polymerase chain reaction for routine identification of M. bovis. All isolated mycoplasmas were identified as Mycoplasma bovis. Mastitic bovine milk originated from a large number of farms in Croatia has been routinely cultured for mycoplasma on appropriate media at Department of Microbiology and Infectious diseases for the last 30 years. On this basis, it is likely that mycoplasma mastitis in Croatia was brought into into the country with the imported animals. As bovine mycoplasma mastitis might be a major udder health problem in dairy cattle there is an urgent necessity of coordinated action of veterinary diagnostic laboratories and veterinary authorities in identifying the distribution and control of this infection in Croatia.
