| Summary: | Aim. So far as one of the additional criteria of species differentiation may be data on the sensitivity of its representatives to antibiotics the aim of this research was to study the susceptibility of the members of P. agglomerans to antibiotics. Methods. To study the antibiotic resistance by disco-diffusion method there were used antibiotics and synthetic antibacterial agents which were different by mechanism of action and chemical structure. Results. It is established that the growth and development of microbial populations of the majority of strains was inhibited by lomefloxacin streptomycin, monomycin, tetracycline, chloramphenicol, polymyxin, and gentamicin, which differ in structure and mechanism of action. To a lesser extent, the investigated strains were sensitive to benzylpenicillin, cefuroxime, сefotaxime, сeftriaxone, сefazolin, kanamycin, rifampcin, ampicillin and furadonin. Resistance to lincomycin and erythromycin showed 92.8% of the studied P. agglomerans strains, while ampicillin and oleandomycin – 84.8% to benzylpencillin, cefuroxime and furazone – 78.5%, to сefazolin and rifampicin – 71.2%, сeftriaxone – 64.1%, to сefotaxime – 57.1%. Conclusion. Thus, two strains (8488 and 8490) can be attributed to one of the same resistentovar as they were resistant to almost the same number of antibiotics and antibacterial drugs (other than lomefloxacin). Four of P. agglomerans strains (П1а, 7960а, 8488, 8490), which displaying resistance to all cephalosporines tested may be included in separate resistentovar. Three of investigated strains (7460, 8456 та 9637) were sensitive to majority of studied antibiotics and antibacterial preparations. And all the others in individual resistentovar. |
