BIODIVERSITY OF COW’S MILK SAMPLES WITH CLINICAL AND SUBCLINICAL MASTITIS
This article was discussed the problems biodiversity of cow mastitis. The purpose of the work was to conduct a statistical analysis of microbiological data milk samples from cows with mastitis in order to ensure the targeted use of antibiotics on Ukrainian farms. Also, the article reveals the problems of the aseptic sampling technique for analysis, which complicates their identification.
The obtained milk samples from 20 farm of Ukraine were examined using microbiology methods. As a result, 41% of all isolated isolates were contagious mastitis agents: 15% of S.aureus and 26% of S.agalactiae, and 59% were environmental mastitis agents. The most bacteria refer to Gram (+) microflora, namely streptococci (22.5% - Streptococcus spp.) and staphylococci (14% -Staphylococcus sspp.). 18.5% of all isolated isolates are identified as Gram (-) microflora: for by Gram (-) microflora: 11% - E.coli, 6% - Pasteurella spp., 1.5% - Proteus spp. Mastitis caused by fungi (yeast), accounted for 1.5% of all diagnosed mastitis. Most of the isolates were sensitive to Amoxicillin + Cl. Acid and Gentamicin -93, 5%. The smallest number of isolates were sensitive to Tylosin- 20,9% and Streptomycin- 48,3%. A significant percentage (83.8% -54.8%) of obtained isolates were sensitive to Rifampicin, Amoxicillin, Bacitracin, Cloxacillin, Trimethoprim, Florfenicol, Ampicillin, Lincomycin, Cephalexin, Enrofloxacin, Neomycin, Penicillin.
