[Serotyping of bacteria of the genus Providencia using the indirect hemagglutination test and the indirect hemagglutination inhibition test].
The experiments with the collection of strains and diagnostic sera available in the USSR confirmed the data contained in the literature on the good prospects of using the indirect hemagglutination test for the serotyping of bacteria belonging to the genus Providencia. Certain differences were observed in cross reactions, revealed by the indirect hemagglutination test and by agglutination: the interrelations of serogroups O14 and O25, O23 and O25, O23 and O29, O29 and O45, O37 and O49, determined by means of the indirect hemagglutination test, could not be detected in the same sera by the slide and tube agglutination tests. For the first time the usefulness of aqueous-saline extracts of agar cultures in the indirect hemagglutination inhibition test to specify more precisely the interrelations between individual bacterial serogroups of the genus Providencia has been shown.
