| Popis: | Subclinical mastitis (SCM) is regarded as both a problem for dairy producers and a threat to human health worldwide owing to the potential bacterial contamination of milk and dairy products, particularly those made from raw milk. In the present study, we isolated Escherichia coli from 14 (9.3%) SCM milk samples. We serotyped each E. coli isolate (n = 14), and investigated its potential pathogenicity and antimicrobial resistance (AMR). The serotyping results showed that the E. coli isolates belonged to serotypes O55:H7 (n = 2), O111:H4 (n = 2), O127:H6 (n = 2), O128:HUT (n = 2), O26:HUT (n = 1), O44:H18 (n = 1), O114:H21 (n = 1), O86:HUT (n = 1), O124:HUT (n = 1), and O127:H7 (n = 1). Potential pathogenicity was detected in 93% (13/14) of the isolates. In particular, 13 isolates possessed at least one of the examined virulence genes. Ten isolates (71%) exhibited AMR to at least one of the tested antimicrobials, four (40%) were multidrug-resistant, and one isolate produced extended-spectrum β-lactamases. The obtained results indicate that SCM acts as a source for the spread of potentially pathogenic E. coli strains that are resistant to many groups of antimicrobials, and may constitute a hazard to both public and animal health. |
