[Antibacterial susceptibility/resistance of Vibrio cholerae eltor clinical strains isolated in the Caucasus during the seventh cholera pandemic].

The data on antibacterial susceptibility and resistance of Vibrio cholerae eltor phenotypes with different sets of the susceptibility or resistance markers conditioning the outbreaks and sporadic cases of cholera in the Caucasus within 1970-1998 are presented. An increase of the number of the Vibrio cholerae phenotypes resistant to tetracycline and chloramphenicol usually used in the treatment of cholera was recorded in 1990-1994 vs. 1970-1989.

HIV drug resistance tendencies in Latvia.

The treatment of HIV infection in Latvia by using highly active antiretroviral therapy (HAART) was started in 1996. The prevalence and tendencies of HIV drug resistance among treated and treatment-naive patients in Latvia in the years 2006-2007 were evaluated in this study. Data of HIV genotyping, performed in 132 HIV-1 infected during years 2006-2007 by TRUGENE HIV-1 genotyping assay (BayerHealthCare-diagnostics) are included in the study.

[An experimental study of the susceptibility of the snakehead Ophiocephalus argus to infestation by larvae of the tapeworm Diphyllobothrium latum].

Experiments were made to infect young Ophiocephalus argus, the fish of prey delivered from eastern Asia in the Amu-Dar'ya River basin, outside the area of the broad tapeworm Diphyllobothrium latum. The dalags were infected mainly by ingesting the local copepods Arctodiaptomus salinus, the experimentally invaded larvae of the broad tapeworm. The latter larvae were obtained from the development of eggs of the helminth isolated from strobilae from the patients treated in Perm Province.

[The etiology of El Tor cholera].

Vibrio cholerae eltor has been shown to exist in two variants: epidemic (V. cholerae eltor Hly-, tox+) and nonepidemic, or endemic (V. cholerae eltor Hly+, tox-); each of these variants determines the corresponding form of manifestation of the infection among the population and requires a differentiated complex of antiepidemic measures, as well as different tactics for the treatment of patients.
