The New Mastitis Agents Emerged in Cattle in Turkey and An Investigation of Their Antimicrobial Susceptibility

Abstract

There are new emerging cattle mastitis agents that have become a major burden economically on the dairy industry because of their negatively affects on production and quality in dairy cattle farming in Turkey,. To overcome this emerged problem, antimicrobials are adopted in this sector to prevent and administrate mastitis and other bacterial infections affecting cattle in the country. Nevertheless, the occurrence of antimicrobial resistance (AMR) is increasing in both animal and human contaminants. The occurrence and features of AMR of the emerging cattle mastitis agents in dairy cattle in Turkey, have been manifested. As a result, the goal of this research was to assess secluded emerging cattle mastitis agents in Turkey and to appraise the antimicrobial susceptibility of these pathogens. Sixty one milk samples from cattle wwith mastitis were collected between 2014 and 2018 for assessment of clinical mastitis in diagnostic and analysis laboratory of Faculty of Veterinary Medicine, Afyon Kocatepe University. Twenty five microorganism species arised as cattle mastitis agents were assessed in these milk samples. The outcomes of the present study identified the necessity for advancements in antimicrobial stewardship as well as infection administration plans in Turkish farms to decrease the occurence of AMR. VITEK Compact® 2 systemmethod showed that Streptococcus uberis had the maximum AMR while Globicatella sulfidifaciens had the minimum AMR. The study depicts that the number of cattle mastitis is directly proportional to the size of the herd.

Isolation of Aerobic Bacteria in Cows With Subclinical Mastitis in Turkey and Evaluation of Their Antimicrobial Suspectibility

“…Milk samples were bacteriologically examined according to the procedure previously described (Kenar et al, 2019). After reaching to the laboratory milk samples were aseptically removed from the cooler box for examination.…”

“…Kenar et al (2019) identified 11 characterized Gram (+) organisms from 61 milk samples of cattle. In addition 50 isolates of Gram (-) fermenting and nonfermenting Burkholdria and B. pseudomallei were screened by Gram stain.…”
