A total of 44 patients suspected of streptococcal infections were studied in outpatient clinics in Tokyo during the one year from December 1988 to December 1989. Employing bacteriological culturing and serodiagnosis, the following results were obtained. 1) There were 9 cases of impetigo and 15 cases of erysipelas with typical clinical manifestations and age distributions. 2) It seemed that some of the skin infections were caused by group A streptococci whose M-types were different from those of upper respiratory infections typically occurring in Japan. 3) The type distribution of group A streptococci found were quite similar to those isolated in Thailand or Malaysia. 4) There were found group A streptococci exhibiting unique combinations of T- and M-types, such as T11 and M9, T11 and M62 or T13-49 and MOD8 (Provisional type). 5) As for serodiagnostic method, ADNB (anti-deoxyribonuclease B) titer reflected infection by group A streptococcus only, while ASK (anti-streptokinase) and ASO (anti-streptolysin O) reflected not only group A streptococcal infections but group G infections as well.

Swine infected experimentally with group E Streptococcus (GES) produced significant antibody titers against streptokinase (streptococcal fibrinolysin, SK) and streptodornase (streptococcal deoxyribonuclease, SD). The antibodies directed against SK (antistreptokinase, ASK) appeared two to nine weeks postexposure and persisted for the duration of the experiment (nearly six months). The ASK inhibited SK produced by GES antigenic types III, IV, and V, by GES devoid of type specific antigen, and by a group P Streptococcus. Selected strains of GES serotypes I and II and group U Streptococcus did not produce detectable SK. The antibodies directed against SD (antistreptodornase, ASD) appeared two to three weeks postexposure, reached a peak about six weeks postexposure, and persisted at high levels for nearly six months (the duration of the experiment). The ASD inhibited SD produced by all known antigenic types of GES, by GES devoid of type specific antigen, and by strains of groups P and U Streptococcus. The antibodies failed to inhibit SD produced by group C Streptococcus. The potential utilization of ASK and ASD titers as serological means of identifying swine infected with GES (carrier swine) is discussed.
