A bacteriological survey -::as carried out in an effort to approximate the present status of the distribution of Shigella species in Korea.
The specimens for the survey v-.-ere obtained by direct rectal swabs both from healthy and diarrhea! persons including specimens from food stuffs and natural environments, which were chosen arbitrarily in thirteen areas of Korea during 1959 to 1971.
Total number of 11, 787 specimens were collected from various sources: 9, 128 rectal swabs from healthy persons and 1, 630 rectal swans from diarrheal patients, and 1, 029 specimens from various food stuffs, sewages and other natural environments,
1. During these three years from 1969 to 1971, 186 Shigella strains of different serotypes were identified from various specimens: 9-1 strains out of 9, 128 rectal swabs from healthy persons, 62 strains from 1, 630 diarrheal cases, 14 strains out of 167 specimens taken from food stuffs including fishes, shellfishes and their products, and 16 strains out of 167 sewage specimens, In the year of 1969, 16 strains of Shigella were isolated from rectal swabs: 4 strains out of 47 specimens from healthy persons and 12 strains from 169 diarrheal cases. In the year of 1970, 101 strains of Shigella were isolated from various specimens: 23 strains out of 751 rectal swabs from healthy persons, 49strains from 1, 347 diarrheal cases, 14 strains out of 136 specimens taken from food stuffs including fishes, shellfishes and their products, and 15 strains out of 94 sewage specimens. In the years of 1971, 69 strains of Shigella were isolated from various sources: 67 strains out of 8, 330 rectal swabs from healthy persons, 1 strans from 114 diarrheal cases, and 1 strains out of 73 sewage specimens.
A striking evidence for the evironmental contamination with Shigella was found in such particular
cities such, as Kangnung, Chumunjin and Incheon in 1970, suggesting further survey has to be done.
2. In this survey it was found that the distribution of Shigella serotypes´were different from that of
hospital sources. Sh. dysenteriae and Sh. boydii were equally prevalent, 0. 45% and 0.35% respectively,
among apparently healthy persons, as th;s survey indicates but Sh, sonner were far less prevalent in
compare with other serotypes among apparently healthy persons.
3. Anual frequency of Sh. dysenteriae and Sh. boydii was, fluctuated with a peak on the year of 1970, still being predominant comparatively. Sh flexneri and Sh. sonnei were found to be decreased from 4.17% to 0.05% and 1.85% to 0.08%, with milder symptomes, respectively.
A considerable number of Alkalescens-Dispar group was still found in 0. 16% from healthy persons.
