ABSTRACT
Biofilm production is an important mechanism for bacterial survival and its occurrence together
with antimicrobial resistance represents a challenge for clinical management. Here, we evaluated
the ability for biofilm production among P. aeruginosa isolates from patients with or without
cystic fibrosis (CF) using two distinct media, besides determining the antimicrobial susceptibility
profile of these isolates for eight antimicrobial agents. The ability for biofilm production when
TSB medium was used was higher than when used CF sputum media (p = 0.0198). However,
P. aeruginosa isolates from CF have demonstrated similar performance for biofilm production, independently
of the medium used. Besides, among the biofilm-producing isolates, those recovered
from CF were more resistant to the carbapenems (meropenem and imipenem) agents than those
isolates from non-CF isolates.
