| Abstract: | Sensitivity to 9 antibiotics of 1040 strains of Proteus belonging to the serological groups 03, 05, 06, 07, 010, 011, 013, 023, 024, 026, 027, 028 and 030 was studied. It was found that the above strains were sensitive and highly sensitive to the aminoglycosides and streptomycin, slightly sensitive to levomycetin and resistant to tetracyclines, erythromycin and penicillin. All the strains were polyresistant and 99.6 per cent of them were resistant to 4--9 antibiotics. Ten types of resistance were found. Proteus strains with the resistance type PETOtCht were most common. No relation between the occurrence of the strains of various serological groups and the character and level of their resistance to the antibiotics was found. |
