[Antibodies to type antigens of group A streptococcal cell walls in erysipelas patients].
The passive hemagglutination test was used to determine antibodies to type antigens of the cell wall of streptococcus group A in 167 patients suffering from erysipelas, from whom 488 sera were obtained. Antibodies were revealed in 97.2% of the sera. There was a definite relationship between the clinical form of the disease and the level of antibodies: their lowest level and the absence of elevation in the course of the disease was noted in continuous-relapsing form of erysipelas; the appearance of antibodies to the new types of streptococcus was usually noted in late relapses of the disease, which permitted to attribute their occurrence to infection by the new types of the microbes. In individual cases the appearance of antibodies to the new types of streptococcus was observed at the early relapses of erysipelas; this could be explained by the exacerbation of a focus of chronic (endogenous) infection in the skin in the absence of reinfection. Continuous prophylactic administration of bicillin-5 produced no depressive effect on the antibody level in patients with relapsing erysipelas.
