[Comparative analysis of methods of diagnosis of chlamydia infection].

In case of a correct sampling, the diagnostic value of optic and electron microscopy for detecting Chlamydia infection is not inferior to that of direct microimmunofluorescence (DMIF) and higher than that of enzyme immunoassay (EIA). Optic microscopy showed that basal vaginal epithelium and buccal mucosa can be infected with Chlamydia. Provazek bodies were detected in the buccal mucosa of the overwhelming majority of patients with genital chlamydiasis.

[Development of a two-site immunoassay using polyclonal antibodies for determination of lactoferrin in human blood].

The two-site enzyme-linked immunosorbent assay (ELISA) for lactoferrin using polyclonal antibodies to spatially distant epitopes has been developed. The assay sensitivity defined as minimal detectable lactoferrin concentration for p = 0.05 is 0.

[The seroepidemiology of toxocariasis in an opisthorchiasis focus in the western Siberian region].

Seroprevalence to Toxocara antigens was studied among Novosibirsk inhabitants and a focus of toxocariasis was found in the southern regions of west Siberia. Analyzing the sera of opisthorchiasis patients revealed antibodies to Toxocara antigens, with high titers (1:800 or more) in 1.80% of cases.
