Abstract

No information is available concerning theantimicrobial susceptibility of Staphylococcus aureus isolatedfrom pigeon slaughterhouses. In the present study,59 staphylococcal strains isolated from a pigeon slaughterhousein central Italy were compared according to theirantibiotic resistance. Onthe basis of cultural and biochemicalproperties, all isolates could be identified as S. aureus.The strains were checked for the productions of enterotoxinsA, B, C, D by reversed passive latex agglutination.Resistance to 26 antibiotics was also determined payingparticular attention to resistance to those antimicrobialagents frequently used in human medicine and in poultrybreeding. Only one strain was positive for the productionof enterotoxins type C and D. It was isolated from theevisceration tube after slaughtering. Enterotoxin B wasproduced by 2 strains isolated from the eyebrows andconjunctivas of the worker operating the crop rinsing tube. As to the susceptibility to antibiotics, all strainswere sensitive to amoxicillin/clavulanic acid, bacitracin,cephalothin, fusidic acid, gentamicin, kanamycin, linezolid,oxacillin, quinupristin/dalfopristin, rifampicin, tobramycin,trimethoprim-sulfamethoxazole, vancomycin.Some (15.2%) of the strains were resistant to ampicillinand to penicillin G; 6.8% were resistant to chloramphenicol,20.3% to enrofloxacin, 16.9% to erythromycin and tociprofloxacin, 8.5% to clindamycin, and 11.9% to lincomycin.The highest percentages of strains were resistant totetracycline and oleandomicin (37.3 and 25.4% respectively).Methicillin-resistant staphylococci were alsofound (3.4%). Only one strain had a multiple antibioticresistance index >0.30. The results were statistically analyzedand clustered in 6 groups. This work provides theantibiotic resistance pattern of S. aureus strains isolatedfrom a pigeon slaughtering plant and represents a studyon a quite unknown field in meat production.[...]
