[Identification of hypervariable and conservative fragments of Listeria genome].

The computer analysis revealed hypervariable and highly conservative fractions in the genes of Gram-positive bacteria of the Listeria genus. As a result of analysis of gene iap coding protein p60, PCR based test systems for detection of 6 Listeria species, L. monocytogenes, L.

[Diagnostic and epidemiological significance of F-donor activity of Enterobacteria strains].

The study of the circulating strains of enteropathogenic Escherichia coli (EPEC), shigellae and salmonellae for the presence of F-factor (the conjunction factor) was carried out. The study revealed that 85% of Shigella flexneri strains 2a had conjugative (F)-factor. The proportion of such strains was 63% among EPEC of different serovars and 15% among Salmonella enteritidis.

[The use of liposomal form of phenylimide of cis-aconitic acid in herpes therapy].

The results of study of the antiviral activity and pharmacokinetics of phenylimide of cis-aconitic acid (PCAA) is presented. The 20% increase of the antiviral activity of PCAA incorporated into liposomes in comparison with the antiviral activity of the pure substance was shown. Liposomes with PCAA were tropic to lymphocytes and macrophages with maximum fluorescence being observed in the spleen, while empty liposomes were accumulated mainly in the liver.

[The results of a 5-year study of listeriosis in Ukraine].

Data on the isolation of Listeria spp. cultures on the territory of Ukraine, the frequency of Listeria contamination of alimentary raw materials and foodstuffs, the level of listeriosis morbidity, the clinical forms of the manifestation of this disease, as well as the occurrence of asymptomatic carriership among clinically healthy persons of epidemiologically significant professions, are given. The results of the study of the biological properties of 73 strains of Listeria spp.

[Listeria bacterial carriage: a method for sanative treatment].

1.6% of clinically healthy women active in certain professions have been found to be carriers of pathogenic species of Listeria. The study of the sensitivity of 73 strains of Listeria spp.

[The possible role of immunogenetic factors in the pathogenesis of HIV infection].

In this review the data on the presence of associations between immunogenetic markers and the development of HIV infection are presented. Special attention is given to spatial relationships of genetic determinants, responsible for the synthesis of the components of the complement system on one hand and the genes controlling resistance to the causative agents of opportunistic infections and malignant growth on the other hand. Suggestion is made on close relationship between the specific features of the course of HIV infection and the genetic control, responsible for the synthesis of complement components, in particular the genes making up the HLA system.
