[The application of micro-cultural enzyme-linked immunosorbent assay of modified immunofluorescence technique for diagnostic of adenovirus infection.]

The particular conditions of professional activities of drafty military personnel determine wide-spread of of respiratory viruses in crew of Armed Forces. The frequent mixing of military staff conditions of carrying of infection agents , including adenoviruses. It is known, that up to 60% of acute respiratory viral disease in newly formed staff have adenovirus etiology. In these cases, the most frequently are isolated serotonins 4 and 7 of adenovirus. The diagnostic possibilities of monoclonal immunologic tests of indirect enzyme-linked immunosorbent assay and micro-cultural enzyme-linked immunosorbent assay for diagnostic of adenovirus infection are investigated. The analysis was applied to 40 clinical samples from patients with diagnosis of acute respiratory viral disease residing for treatment in military medical organizations during April-June 2014. The culture of cells A-549 infected with materials from patients was used for analysis. The evaluation of reproduction of adenovirus in infected culture of cells using both techniques was implemented by application of monoclonal antibodies to hexon of adenovirus on stage of detection. The availability of adenovirus was proved applying polymerase chain reaction in 20 samples; isolation of cell culture in 19 samples; indirect enzyme-linked immunosorbent assay - in 14 samples; micro-cultural enzyme-linked immunosorbent assay - in 14 samples. For detection of serotypes of adenovirus isolation of DNA and sequencing of 10 of analyzed samples positive for adenovirus according results of polymerase chain reaction were implemented. The results of phylogenetic analysis on site of gene string demonstrated belonging pofadenovirus out of all samples to serotype 4 (subgroup E). The sensitivity of indirect enzyme-linked immunosorbent assay and micro-cultural enzyme-linked immunosorbent assay in detection of adenovirus in cell cultures infected with materials from patients, in comparison with polymerase chain reaction, made up to 85% and 87% correspondingly. The specificity of both techniques reached 100%.

[The diagnostic value of serological and molecular genetic methods in detection of German measles disease].

The early diagnostic of German measles infection, especially in cases requiring differential diagnostic search, the most informative and usable in practice test-systems are needed to be applied. The sampling of patients (n = 37) included males aged from 15 to 21 year (average age - 18 years) were admitted to hospital on 1-3 day from onset of disease. The technique of polymerase chain reaction with reverse transcription was applied to detect presence of viral RNA in nasopharyngital smear. The presence of viral RNA was confirmed in 26 examined patients (70%). The serological markers of onset of disease at the moment of first examination had 24 (65%) out of 37 patients. It is demonstrated that technique of polymerase chain reaction with reverse transcription has the most diagnostic value in confirmation of diagnosis of German measles infection at the first days of disease. In the sequel, the informativeness of methods of serological diagnostic will increase because complex application of methods of IgM and polymerase chain reaction with reverse transcription are needed at different periods of disease.
