Species diversity and antibiotic-resistance of bacteria allocated from various animal classes in Dnepropetrovsk region
The screening studies results analysis was carried out for microflora isolated and identified by veterinary laboratories of Dnipropetrovsk region during 2016-2017. Biological material was obtained from agricultural enterprises and the private sector of Ukraine's central region. According to the research results, the predominance of multidrugresistant gram-negative bacteria was established. According to occurrence frequency the main dominant species - Escherichia coli (33,8 %) and subdominant species were determined. Dominant species representatives prevailed among the bacteria isolated from pathological material of poultry (48,3 %). Correlation links analysis for the resistance of E. coli and other microorganisms resulted in establishing the specific features of the antibiotic resistance formation. It has been established that circulating enzootic variants of E. coli in Dnepropetrovsk region are enteropathogenic and enterotoxigenic serological groups.
