[Prevalence of hemolytic streptococcal infection in Kitakyushu: incidence and characteristics of isolates (1994-1997)].
In the study of prevalence of hemolytic streptococci in Kitakyushu-city from 1994 to 1997, both seasonal variation of the number of group A hemolytic streptococci isolates and their age distribution fitted in well with the cases of streptococcal infection which is monitored in the Japanese infectious disease surveillance system. Dominant serotypes of group A hemolytic streptococci in Kitakyushu-city were T-12 and T-3 from 1994 to 1995, T-28 and T-12 in 1996, T-2 and T-4 in 1997. Compared with prevalent serotypes of group A hemolytic streptococci in the City and those in Japan, the geographically close relation was observed. The epidemic serotypes in the City tended to fall behind those in Honshu, the main land of Japan. Most of the isolates were resistant to kanamycin (KM). Few isolates were resistant to other drugs except tetracycline (TC), to which 14% of the isolates were resistant. Strains of multiple-drug resistant were less than 5%. Gene of speB was detected in all group A strains by PCR method, and a close relationship was observed between T-type and SPE gene type.
