- Abstract
The purpose of this study was to characterize Escherichia coli (E. coli) strains isolated from wild black grouse (Lyrurus tetrix), carried out due to the crossing of hiking trails with wild bird habitats from the Karkonosze National Park. Twenty-seven E. coli isolates were obtained from fecal samples collected during the winter months of 2017 and 2018. The strains were assigned to their relevant phylo-groups and the prevalence of virulence genes characteristic of APEC strains (irp2, astA, iss, iucD, papC, tsh, vat, cva/cvi, stx2f) was checked using PCR analysis. In addition, the phenotypic and genotypic resistance to antibiotics was determined. The entire study provided a better understanding of the potential bacteriological threat to wild birds of the Karkonosze National Park. The results showed that 55.6% of the strains belonged to phylo-group B1 (15/27), 33.3% to group B2 (9/27) and 11.1% to group D (3/27). Among the virulence genes tested, irp2 was detected in 25.9% of isolates (7/27), vat in 22.2% (6/27) and iucD in 3.7% (1/27). The tested E. coli strains showed susceptibility to most antimicrobials, only 14 (51.9%) of them were intermediate resistant or resistant to sulfamethoxazole. The presence of none of the tested genes responsible for resistance to selected antibiotics was identified. Our research indicates a low level of transfer of antimicrobial substances to the natural environment and confirms the effectiveness of the Karkonosze National Park's activities to protect and restore black grouse habitats.
