[Adequate selection of antigens for serologic diagnostics of experimental melioidosis].

Sera of Burkholderia pseudomallei-infected golden hamsters, white mice, guinea pigs and white rats were studied. Immunochemical analysis revealed presence of antibodies against antigens 2, 3, 6, d, and g with significant predominance of antibodies to antigens 6 and d. Antigen d was detected irrespectively to strain used for experimental infection and experimental animal species. Antibodies to antigen 6 were detected only when strains belonging to Asian serovar, but not to Australian serovar, were used. On the basis of antigens 6 and d following methods of serologic diagnostics were developed: reaction of indirect hemagglutination, reaction of latex agglutination, and radioimmunological assay. Their sensitivity and specificity reached 100% during experimental melioidosis in golden hamsters, guinea pigs and white rats.
