[Antibiotic sensitivity of El Tor Vibrio cholerae after exposure to various pesticides and mineral fertilizers]. / Antibiotikochuvstvitel'nost' kholernykh vibrionov El'-Tor, podvergnutykh vozdeistviiu nekotorykh pestitsidov i mineral'nykh udobranii.

The strains of El Tor Vibrio cholerae were exposed to different concentrations of pesticides (fazolone, treflane, prometrine, magnesium chlorate, omait and gardon) and mineral fertilizers (superphosphate, ammophos and carbamide) for 2 to 135 days. The subcultures of various ages were tested for their sensitivity to 16 antibiotics. The whole of 229 cultures were tested. There was a general tendency to lowering of the El Tor vibrio sensitivity to the majority of the antibiotics tested. The vibrio strains resistant to the antibiotics widely used in medical practice i. e. levomycetin, streptomycin, tetracycline, lincomycin, neomycin and kanamycin were isolated.

[Serovars of nonagglutinating vibrios isolated on the territory of the Uzbek SSR and their role in the development of acute intestinal diseases]. / O serovarakh neaggliutiniruiushchikhsia vobrionov, vydelennykh na territorii Uzbekskoi SSR, i ikh roli v razvitii ostrykh kishechnykh zabolevanii.

As the result of the serotyping of 1,223 NAG vibrio strains isolated in the Uzbek SSR from the environment and 659 strains isolated from gastroenteritis patients and from vibriocarriers, the serovars of 563 strains (46%) and 420 strains (63%), respectively, were determined. The prevailing serovars were 08, 06, 09, 014, 05, 039, 041, 013, 019 among the strains isolated from the environment and 08, 041, 037, 05, 039, 024, 06 among the strains isolated from humans. The strains belonging to serovars 05, 06, 08, 024, 037, 039, 041 were isolated both from the environment and from humans. The possible role of these strains in the development of acute gastroenteritis and in the formation of vibriocarriership in humans is pointed out.
