The work deals with the results of determination of specific antibodies in blood donors of Moscow and Tula and in patients with alimentary toxicoinfection, made with the use of enzyme immunoassay on the basis of Yersinia enterocolitica lipopolysaccharides (LPS), serovars O3 and O9. The sera of patients with alimentary toxicoinfection were found to yield(More)
In the process the cultivation of H. influenzae, type b, in semisynthetic nutrient medium with aminopeptide base the growth of the bacteria and the synthesis of capsular polysaccharide were shown to depend on the concentrations of aminopeptide, nicotinamide adenine nucleotide (NAD) and hemin. An increase in the concentrations of NAD and hemin stimulated the(More)
124 sera of children with chronic bronchitis, chronic pneumonia, bronchial asthma, exogenic allergic alveolitis, congenital developmental defects of the lungs and the syndrome of the situs inversus of organs were examined with a view to study the state of humoral immunity to tissues. The study was carried out by means of the enzyme-linked immunosorbent(More)
Solid-phase EIA was used to titer antibodies to polysaccharide and ultrasonic disintegrate antigens of the most incident agents of anaerobic infections of the maxillofacial area. Comparison of the results of EIA with polysaccharide antigens of B.melaninogenicus, B.asaccharolyticus, F.nucleatum, P.intermedius, and Str.sanguis and the results of(More)
Presence of IgG autoantibodies to broad spectrum of tissues' antigens in patients with diabetic retinopathy under type I diabetes mellitus was studied. Increased levels of antibodies to different antigens were observed in 56% of patients. Increased levels of antibodies to hypophysis, denaturated DNA, and myelin basic protein were detected most frequently.(More)
Electron microscopic study of the microbial cells of the I, II phases and the R-form was carried out. Intact cells were examined by negative contrasting, and morphological differences of various bacterial phases were shown: cells of the I phase had a relatively smooth surface, bacteria of the II phase had a smooth surface, but many cell wall fragments were(More)
In 186 patients with odontogenic infection the level of antibodies to B.melaninogenicus polysaccharide antigen, teichoic acid and S.aureus polysaccharide was determined in the enzyme-linked immunosorbent assay (ELISA). The positive values of ELISA indices were found to coincide with the data of bacteriological study in more than 90% of cases. The role of(More)
To develop an immunoenzymatic system, the preparations of teichoic acid (TA) isolated from the Staphylococcus aureus strain Wood 46 were used. The TA-based ELISA technique made it possible to diagnose infectious endocarditis of staphylococcal etiology. Further investigations are necessary to ascertain the possibility of using this system for diagnosing(More)
The authors present the results of studying the weakly immunogenic Citrobacter strains; some O-antigens of Citrobacter (11, 14, 19, 21a, 21b, 26) caused in immunization of rabbits a weak immune response (antibody titre--1:400-1:800). An electron microscopic study of the vaccines (obtained from these strains) and their fragments showed that a partial(More)
