[Sensitivity of Shigella to antibiotics].

Three hundred and twenty two Shigella cultures isolated from dysentery patients within 1986-1989 were tested with the use of standard paper disks for their sensitivity to levomycetin, streptomycin, tetracycline, monomycin, neomycin, kanamycin, erythromycin, gentamicin, carbenicillin, ampicillin, oxacillin, methicillin and doxycycline. The number of the cultures belonging to Shigella sonnei amounted to 85.1 per cent of the total number of the strains studied.

[Antibiotic sensitivity of Shigella isolated from patients from 1974-1985].

Antibiotic sensitivity of 3524 Shigella cultures isolated from patients in 1974-1982 and 414 cultures isolated in 1983-1985 was assayed with standard paper disks. The isolates of 1974-1982 were mostly responsive to ampicillin, carbenicillin, kanamycin, gentamicin, monomycin, neomycin and chloramphenicol. Certain differences in the level of the antibiotic resistance were observed in the Shigella isolates belonging to diverse species.

[Salmonellal sensitivity to antibiotics in 1975-1979 and its characteristics in S. typhimurium].

Sensitivity of 314 Salmonella strains of 16 serotypes of the main groups ABCDE isolated from patients with salmonellosis in 1975-1979 was studied with the method of standard paper disks with respect to levomycetin, streptomycin, tetracycline, monomycin, erythromycin, oleandomycin and in a part of the cultures to kanamycin, ristomycin, ampicillin, carbenicillin and polymyxin. 78 per cent of the strains fell within S. typhimurium.
