Abstract: Phage type M1 was most frequently found (44%) among 190 Salmonella typhi strains isolated from sporadic cases in South Korea. An epidemic of typhoid has broken out in a province, 60 isolates from which were typed in all as type A. Phage types of S. typhi in Taiwan was extremely rich in variety, among them some rare phage types like G, E9 and T were found. There was no appreciable difference in drug sensitivity between S. typhi isolated in Korea and Taiwan on one hand, and between the strains from sporadic and epidemic cases in Korea on the other hand. The results of serotype determination, biochemical study and drug sensitivity tests in 78 salmonellae other than S. typhi are also presented. Sixty strains among them were of human source, and were forwarded to the laboratory for identification from Korea, Taiwan, the Philippines, and some public health institutions in Nagasaki. The remaining 18 strains were those isolated from laboratory animals in Taiwan. It is noteworthy that S. paratyphi C was found only in Korea, S. typhimurium was more frequent in the other countries, and, in the Philippines, two multiply resistant strains showing resistance extending over kanamycin, aminobenzil-penicillin and fradiomycin were isolated. In addition, it was observed that all salmonellae and shigellae used, numbering 363 and 47 respectively, showred a high sensitivity to furazolidone and furatrizine, especially to the latter. The most prevalent colicin type of Shigella sonnei in Taiwan was type 8, whereas in Hong Kong, type 9A. Distinct differences with regard to biochemical type and drug-resistance pattern of this organism were not observed between the two countries. Out of a total of 56 halophilic bacteria, isolated from sea-water and fishes in Taiwan, only one strain was determined as sucrose negative, hemolytic and K-typable Vibrio parahaemolyticus. / 韓国の散発例分離チフス菌190株のうちではファージ型M1が最も多かった.同国で腸チフスの集団発生があったが,その分離菌のファージ型はすべてA型であった.台湾分離チフス菌のファージ型は極めて多彩で,そのなかにはG,E9,Tのような稀有型もみられた.韓国と台湾分離チフス菌の薬剤感受性には特記すべき差異がなく,韓国の散発株と集発株を比較しても同様であった.チフス菌以外のサルモネラ78株の血清型決定,生化学的研究,薬剤感受性試験の成績も提示されている.そのうち60株は韓国,台湾とフイリピンからおよび長崎県下の保健所などから送られてきた人系株,残る18株は台湾で実験動物から分離されたものであった.パラチフスC菌が韓国だけで見出されたこと,S. typhimuriumはその他の国で最もしばしばみられたこと,それとフィリピンで,カナマイシン,アミノベンチールペニシリンからフラジオマイシンにも及ぶ多剤耐性菌2株が検出されたことは特記の要がある.これに加えて,使用したサルモネラ363株と赤痢菌47株はフラゾリドンとフラトリジンに対し,特に後者に対して高い感受性を示した.赤痢ソンネ菌のコリシン型として台湾で最も多かったのは8型,香港では9A型であった.同菌の生化学型と薬剤耐性パターンについては両地間に特に明確な差異を認めなかった.台湾で海水と魚類から分離した好塩菌は56株,V. parahaemolyticusとしては15株であったが,このうち白糖非分解,溶血性,K型別可能のものは僅か1株にすぎなかった.
