Abstract

The cholera prevailed at Taegu, Korea in August, 1970 was analysed for the epidemiological and bacteriological determinations from true and suspicious, total 109, cases which were admitted to Kyungpook National University Hospital. The results were as followings: 1. The isolation rate of cholera was 33.0% (36 cases) from stool culture. 2. The incidence on sex and age showed that the female group was more than 2 times higher than the male group and more high in twenties group in the female but thirties in the male group. 3. The consistencies of the feces were rice watery in 7 cases (19.4%), diarrheal in 25 cases (65.5%) and formular in 4 cases (11.1%). 4. The excretion of bacteria in feces was continued to the 5∼6th day in most cases, however there was no case continuing the excretion of bacteria from feces beyond 10th day. 5. All of the true cases were the inhibitants of peripheral area of the city or country near the city. 6. The suspected intermediate as an infectious source was generally likely to be sea fishes, fruits and sea plant etc. in order but it was impossible to determine the primary source of the infection. 7. The isolated organism was serologically Ogawa type and revealed positive indole test, Voges-Proskauer test, cholera red test, hemolytic reaction and hemagglutination test on hen red cells in most strains and were resistant to phage type IV in all strains tested. On the carbohydrate fermentation test, glucose and sucrose were fermented but lactose, mannitol, maltose and arabinose were not fermented in most strains. The sensitivity test to the various antibiotics revealed high sensitivity to streptomycin, chloramphenicol, eythromycin and penbritin but there was a tendency of resistance to tetracyclin is tested strains.
