Resistance to antibiotics and production of beta-lactamase in Plesiomonas shigelloides strains isolated in animals

Veterinarni Medicina 45, 2000, 261-265

This research paper studies the resistance to antibiotics and the production of beta -lactamase in Plesiomonas shigelloides strains isolated in animal population and environment in the Moravian region of the Czech Republic. At the National Veterinary Institute Olomouc in the period of 1994-1999, 6 370 samples of sectional, clinical material and environment have been examined for the presence of Plesiomonas shigelloides, out of which 75 strains have been isolated (1.2%). The isolated strains have been tested for beta -lactamase production and sensitivity to 12 selected antibiotics. The production of beta -lactamase was detected in 96% of the tested strains. 100% of the strains are resistant to penicillin and streptomycin. All strains were susceptible to aminopenicillins combined with beta -lactamase inhibitors (ampicillin/sulbactam, amoxicillin/clavulanic acid), chloramphenicol, tetracycline, co-trimoxazole, ciprofloxacin, cefoperazone and norfloxacin
