[Antibiotic resistance of Campylobacter and its epidemiologic significance]. / Antibiotikorezistentnost' kampilobakterii i ee épidemiologicheskoe znachenie.

Sensitivity of 179 strains of thermophilic Campylobacter to 21 chemotherapeutic drugs was studied. Activity of the antibacterial agents against the pathogens was estimated by the MICs. The MIC50 and MIC90 were also determined. All the Campylobacter strains were sensitive to gentamicin, chloramphenicol, neomycin, furazolidone and furagin and resistant to cefazolin, polymyxin E, rifampicin, vancomycin and bacitracin. Differences in the attitude of the Campylobacter isolates from various sources and patients of various age groups to the chemotherapeutic drugs were detected. Possible consideration of the results of comparison of R spectra of Campylobacter strains and the levels of their resistance to antimicrobial drugs as epidemiological markers is discussed.

[Clinico-epidemiologic aspects of campylobacteriosis in Moscow and Moscow Province]. / Kliniko-épidemiologicheskie aspekty kampilobakterioza v Moskve i Moskovskoi oblasti.

The clinical course and epidemiological features of campylobacteriosis in Moscow and Moscow Province in 1986-1987 are described. The specific proportion of this infection in the structure of acute enteric infections is, on the average, 4.8%. The level of Campylobacter contamination of animals and birds and their role in the spread of campylobacteriosis have been established. The possible ways and factors of the transfer of this infection are discussed.

[Detection of Campylobacter pylori in children with chronic gastritis]. / Obnaruzhenie Campylobacter pylori u detei, stradaiushchikh khronicheskim gastritom.

Examinations of the gastric mucosa biopsy specimens from 38 children suffering from chronic gastritis have revealed Campylobacter bacteria in 21 (55.3%). Studies of the cultural, morphologic, and biochemical characteristics of the isolated strains have identified them as C. pylori.

[Clinico-endoscopic characteristics and laboratory diagnosis of chronic Campylobacter gastritis in childhood]. / Kliniko-éndoskopicheskie osobennosti i laboratornaia diagnostika khronicheskogo kampilobakterioznogo gastrita v detskom vozraste.

Altogether 31 children with chronic gastritis were examined. Three diagnostic tests were employed for detecting Campylobacter pylori. The clinical signs of the disease and the endoscopic features of the gastric mucosa are described.

Development of a nutrient medium to culture microorganisms of the genus Campylobacter.

The nutrient media developed in the USSR and CSR for the isolation of campylobacteria are multi-purpose as they enable the isolation of campylobacteria not only from material derived from patients with acute intestinal infection, but also from the internal organs of healthy and diseased animals and poultry as well as from a variety of objects in the environment.

[Etiological structure of salmonellosis and the serotype passage of salmonellae isolated in separate regions of the USSR in 1980-1982]. / Etiologicheskaia struktura sal'monellezov i serotipovoi peizazh sal'monell, vydelennykh na otdel'nykh territoriiakh strany v 1980-1982 gg.

At the period of 1980-1982 the isolation of salmonellae belonging to 394 serovars was registered in the USSR. Of these, 116 Salmonella serovars were registered in the USSR for the first time. 12 dominating serovars constituted 83.1% of salmonellae isolated from humans, 99% of salmonellae isolated from animals and 70% of all salmonellae isolated from different environmental objects. S. typhimurium was the predominant serovar, found to determine 50% of cases of Salmonella infection. The isolation rate of S. infantis and S. virchow was shown to increase. The existence of definite ecological relationships between infective agents isolated from different sources was established.
