Abstract
In this study, fifty Moraxella species were isolated. The antibiotic susceptibility, β-lactamases and minimum inhibitory and bactericidal concentrations were evaluated. The rate of ESBLs among M. catarrhalis, M. osloensis and M. lacunata included 47 % (n=11), 36.84 % (n=7) and 37.5 % (n=3), respectively. ...

In this study, fifty Moraxella species were isolated. The antibiotic susceptibility, β-lactamases and minimum inhibitory and bactericidal concentrations were evaluated. The rate of ESBLs among M. catarrhalis, M. osloensis and M. lacunata included 47 % (n=11), 36.84 % (n=7) and 37.5 % (n=3), respectively. The strong biofilm formation was observed among 52 %, 63.5 % and 62.5 % of M. catarrhalis, M. osloensis and M. lacunata, respectively. The rate of the bro1, bro2 and blaCTX-M1 genes in M. catarrhalis included 23/23 (100 %), 12/23 (52.17 %) and 5/23 (21.8 %), respectively. Moreover, 14/19 (73.68 %), 8/19 (42.10 %) and 2/19 (10.52 %) of M. osloensis, respectively contained these genes. The bro1 gene was detected in all the M. lacunata isolates. Moraxella spp highly produced BRO β-lactamases and ESBLs, and deciphered strong biofilm formation.
