최재두,이연태,정태화,Choi, Jae-Doo,Lee, Yun-Tai,Jung, Tae-Hwoa 대한미생물학회 1987 大韓微生物學會誌 Vol.22 No.1
The result of various researches mainly in search of 194 Shigella strains, isolated by the Health Research Centers(situated in Seoul city, Inchon city, Pusan city, Kyonggi-Do, Kangwon-Do, Chungchongnam and Buk-Do, Kyongsangnam and Buk-Do, Jollanam and Buk-Do, and Jaeju-Do) in addition to those clinical laboratories of all the general hospitals situated down twon Seoul, conducted during the month of Jan. through Dec. 85, through the reisolating-activity program following its transportation into the laboratory, particularly for a complete check on its correctiveness, are as follows: 1. Isolation processes were performed with the 194 strains obtained from each placeduring the period of investigation: 164 Strains(84.5%) of Sh. flexneri, B group; 6 Strains(3.1%) of Sh. boydii, C group; 24 Strains(12.3%) of Sh. sonnei, D group, which means there's quite a lot in B group while Sh. dysenteriae, A group was not isolated at all. 2. The isolation rate of the 164, B group for subserotype was 1b, 84(51.2%) the highest one, 2(1.2%) on 3a the lowest one, 4, on C group; In D group subserotype II showed 14(58.4%) more than subserotype I. 3. The biological data on sexuality regarding the isolation-strain showed traditional particularity. But the subserotype 1b in B group 2(2.4%) showed gas-growth from glucose. In subserotype 1a, the indole-growth was 88.9% on masculine which was considerably a good one. In the test of arginine dihydrolase subserotype I among D group showed 100% masculine rate. The subserotype 6 among B group showed 92.5% masculine. In the dissolution test of manitol, all subserotypes showed 100% maculine except subserotype 1b. In the dissolutioning test of rhamnose, the subserotype I among D group showed 100% masculine which is the unusual one. 4. Interms of the area among 13 districts examined, Kangwon-Do had 41(21.1%) which is the highest one on its ratio. 5. In terms of season on the strain isolation category, 44(22.7%) is the number isolated in April which is the highest one. 6. In terms of ages, the strain isolation ratio was notably high above the ages of 60 which was 34(17.5%). Next one was 29(14.9%) which was under the ages of 4. 7. In terms of sex, female was 113 or 58.2% while male was 74 or 38.2%, which means the female had more than the male. 8. The result of the resisting capability on the usage of 12 antibiotic medication was; 100% on chloramphenicol; 94.3% on tetracycline, 82.0% on streptomycin, 76.3% on carbenicillin, 74.7% on ampicillin, in regular order. The strain source bearing multimedication resisivity against the 5 antibiotic medication is as many as 117 or 60.3%. Of which 43.3% of 1b sub serotype, B group was the best one, and thus the resistivity against the antistrain medication seems the tendency is being changed. The summing up of the above result shows the total specific strains isolated in each branch in Korea is 194, of which the main type is Sh. flexneri 84.5%. The isolating rate is almost evenly spreading, although the Kangwon-Do showed the highest rate on the above data. It also shows female is higher than male on its statistics. The tendency on age category showed both on old and infancy generations high. However, the resistant capability against antibacteria medication or vaccine was still remaining on habitual one, particularly tending towards multimedication or vaccine trend.

Ampicillin과 Chloramphenicol 내성 Salmonella typhimurium 분리의 증가
정윤섭,한상순,권오헌,이삼열,정태화,Chong, Yun-Sop,Han, Sang-Soon,Kwon, Oh-Hun,Lee, Samuel.Y.,Jung, Tae-Hwoa 대한미생물학회 1987 大韓微生物學會誌 Vol.22 No.1
Salmonella typhi infection, which was the most frequent enteric infection in Korea, has been decreasing, while the infection of other serogroups of Salmonella has been increasing since the later part of 1970s. In 1986, the number of serogroup B isolated by us increased to 46, which corresponds 21.1% of all enteropathogenic bacteria isolated from stool specimens. Salmonella isolates resistant to antimicrobial agents were extremly rare in Korea, in the 1970s. However, 7 of 13 serogroup B isolates showed resistance to ampicillin or to chloramphenicol in 1984. Among the serogroup B isolates in 1986, 71.7% and 69.6% were resistant to ampicillin and to chloramphenicol respectively. The minimum inhibitory concentrations of ampicillin and chloramphenicol against these isolates were >$128\;{\mu}g/ml$ and $128\;{\mu}g/ml$ respectively.

In order to determine the virulence properties of eleven strains of Sh, flexneri isolated from diarr- heal patients the congo red test, the Sereny test, the I-leLa cell invasion test and etectrophotesis of pl- asmids were carried out. The results were summarized as follows. 1. Virulent strains were not determined by the result of Congo red absorption test. 2. Virulent strains showed positive reaction by the Sereny test and the HeLa cells invasion, but aviru- lent strains revealed negative reaction at those tests. 3. The temperature condition of bacterial growth was a factor of viru lent expression. 4. Virulent strains were mostly possessed of a 130.3 Mdal plasmid, but avirulent strains were not.
