The summary and the results of epidemiological investigation of scarlatina-like disease which prevailed at N nursery school in Toyota-cho during from September to October in 1974 were as follows.<BR>The first patient infected with this disease appeared around the 17th September, and then the appearances sporadically continued, particulaly 16 absences out of 48 pupils occurred two days later than the 6th October when the joint athletic meeting of neighboring nurseries was held. Because of this, a countermeasure of temporary closing of nursery was taken, and by bacterological examinations and so on, T type 12 streptococci of A group were isolated from all tested nursery children.<BR>It was marked that T type 12 streptococci of A group were also isolated from 26% of the pupils by a carrier examination after 6 months.<BR>As controls, both A and B nurseries of Toyota-cho in the same district as N nursery as well as both C and D nurseries in neighboring district of Mine-city were investigated. The rate of carrying hemolytic streptococci (HS) of A nursery was 34%, and type of HS was 12 type. B nursery, 25% with 5/27/44 type and UT of HS. On the other hand, the rates of carrying HS of C and D nurseries in Mine-city district were both 10.9%, the former was 5/27/44 type, 12 type and UT, and the latter was all UT. It was noted that the rate of carrying HS in Toyota-cho district was much higher than that of Mine-city district.<BR>As regards drug sensitivity pattern, the strain derived from N, A and B nurseries in Toyota--cho district and C nursery in Mine-city district showed a tendency of resistant against TC and EM independent of the type of HS. Contrary to it, the strain derived from D nursery showed a high sensitivity pattern.
