Due to its ubiquity, ability to form biofilms, and acquire resistance mechanisms, Pseudomonas spp. become one of the major
challenge for healthcare settings and food industry. The aims of this study were to assess the biofilm production of Pseudomonas
spp. recovered from clinical and food specimens and to evaluate their antimicrobial resistance. A total of 108
isolates of Pseudomonas spp. were included in the study, 48 being clinical isolates recovered from patients admitted to four
tertiary care hospitals throughout Serbia and 60 were isolated from the bulk tank milk samples and meat carcasses. Biofilm
production was analyzed by microtiter plate assay. Antimicrobial susceptibility was evaluated by disk diffusion method
according to the CLSI guidelines, while class A and B β-lactamases encoding genes were screened by PCR. A total of 98
(90.7%) strains were biofilm producers (moderate producer: 68, 69.4%; strong producer: 8, 8.2%). Although a slightly higher
percentage of clinic...al isolates were biofilm producers (91.7%) compared to food isolates (90%), statistical significance was
not observed (P > 0.05). The proportion of carbapenem-resistant Pseudomonas aeruginosa (CRPA) isolates was significantly
higher among clinical (42%) isolates compared to food (1.7%) Pseudomonads (P < 0.05). The blaPER and blaNDM genes were
found in ESBL (seven isolates) and MBL (two isolates) production, respectively. In the present study, we confirmed that
biofilm formation was highly present in both clinical and food Pseudomonas spp. irrespective of the prior existence of resistance
genes. Additionally, clinical settings pose a major reservoir of MDR Pseudomonas spp. and especially CRPA isolates.
