| Summary: | The genus Bacillusis frequently found in soil, water and food. Bacillus cereus and Bacillusanthracis are the main pathogens causing foodborne diseases and seriousinfections in humans. A total of 52 Bacillusspp. from meat samples was tested for determination of biofilm production, antimicrobialresistance pattern and beta-lactamase activity. The 24 (46.1%) Bacillus isolates were found to be forbiofilm production. Of the 24 (46.1%) biofilm producer Bacillus isolates, 13 (25%), 6 (11.5%) and 5 (9.6%) were consideredas strong, moderate and weak biofilm producer, respectively. The most common speciesfor the production of biofilm was Bacillusthuringiensis (80%). Antimicrobial disk susceptibility tests of Bacillus spp. revealed high resistanceto ampicillin (84.6%) followed by penicillin (75%), cefepime (34.6%), andcefoxitin (26.9%). A multidrug resistance to at least 3 or more antimicrobialswas observed in the 25 isolates (48.1%). All Bacillus spp. were sensitive to vancomycin, gentamicin, amikacin, ciprofloxacin,and imipenem. The susceptibility rate to streptomycin, chloramphenicol, andtrimethoprim-sulphamethoxazole was 94.2%. Among the isolates, the 6 (11.5%) isolateswere found to be sensitive to all antimicrobial agents tested. Besides, onlyone isolate from meat was found to be positive for beta-lactamase test. Theexistence of biofilm production as a virulence factor and of multidrugresistance in bacteria isolated from food should not be underestimated in termsof food safety, public health and economic concerns. |
