Isolation of Microorganisms from Cows with Clinical Metritis

Clinical metritis is a common reproductive tract desease, caused by oportunistic microorganisms. It is present in up to 20 - 40% of dairy cows and occurs within 21 days of parturition. Metritis is characterized by enlarge uterus, pyrexia (T > 39,5°C) and watery red-brown fluid to viscous off-white purulent uterine discharge, which has a fetid odour. The most important risk factors associates with metritis include dystocia, male offspring, stillbirth, twins and retained placenta. Aim of research: Isolate microorganisms from the dairy cows, with clinical metritis and determine it resistence to antimicrobial agents Materials and methods: Research was done during the period of 2017–2018 year. The samples was collected from twenty-five dairy cows with clinical metritis. The samples of uterine discharge were delivered to microbiology laboratory within 24 hours. The bacteriology analysis and antimicrobial susceptibility tests were done at lobaratory. Results: Microorganisms were obtained from 92% samples. The hightest prevalence had Escherichia coli (70%), Trueperella pyogenes, and Streptococcus dysgalactiae (9%). Obtained microorganisms were most resistant to ceftazidim (91,3%) and cefaclor (65,2%). The most dairy with clinical metritis was primiparous (36%) and with hight milk yields (over 35 liters/day) - (60%)
