Fig. 9.1
Frequency of the antimicrobial resistances (%) in UPEC strains isolated from dogs and cats
A large number of isolates were resistant to cephalosporins, specifically to the third-generation drugs, while the lowest level of resistance was found to SXT.
E. coli strains isolated from dogs and cats showed similar antimicrobial profiles, and no statistically significant differences between two species were observed, except for cefovecin (p < 0.05).
Antibiotic-resistant isolates belonged to all phylogenetic groups (57% B2; 43% non-B2), while susceptible strains were associated almost exclusively in group B2 (90%) with a smaller percentage in group D (10%; Table 9.1).
