Abstract
|
|
|
The biochemical reactions and the chemotherapeutic agents sensitivity test to the cholera El Tor vibrio strains isolated from the cholera epidemics in Pusan and Kyungnam province in 1969-1970 were studied and the following results were obtained.
1. The cholera red test to the isolated strains were all positive, but M-R and V-P tests were showed various patterns.
2. On the hemolysis test to the isolated 68 strains in 1969 epidemic were positive for only 2 strains (2. 9%), but the 80 strains isolated in 1970 epidemic were showed all negative results.
3. Hemagglutination test with slide glass method to the isolated strains were showed all positive results. The order of intensity of hemagglutination reactions were showed the guinea pig, rabbit, chicken, human, and sheep erythrocytes.
4. The isolated strains were growth on the range from 0% NaCl to 4% NaCl in alkaline 1% peptone water, but growth was inhibited in over 5% NaCl in alkaline 1% peptone water.
5. The isolated strains were growth on the range from pH 6. 0 to 10. 0 in 0.5% NaCl in 1% peptone water.
6. Sensitivity test of colistin containing 1000 units with paper disk (6. 5mm in diameter) method to the 388 isolated strains were showed the following results: 277 strains (71.3%) were resistant, and 14 strains (3.6%) were showed 10mm inhibition zone, 2 strains (0. 6%)
were showed 15mm inhibition zone.
7. The result of sensitivity test to eight different chemotherapeutic agents were sensitive to chloramphenicol, erythromycin (100%), Bactrim (95. 0%), teracycline(90.0%) sulfadiazine
