光州川에서 分離한 Proteus屬의 生化學的性狀 및 抗菌劑 感受性에 관한 硏究 = A Study on the Biochemical characteristics, susceptibility to Antimicrobial agents of the Genus proteus isolated from Kwang-Ju Rive

다국어 초록 (Multilingual Abstract)

Using the law of Edwards-Ewing and Minitek System, it will be shown that Proteus Enterobacteria was detected in Kwangju River. When the biochemical characteristics and antibiotic susceptibility were tested for the 32 Proteus strains identified in the Enterobacteria in which lactose non-fermentation and an oxidase non-reactive character were discovered. Thc following results were obtained.
1. The isolated strains were as follows :
P. vulgaris : 3 strains. P. mirabilis : 3 strains.
P. morganii : 1 strain. P. rettgeri : 25 strains.
2. Biotype IV (14 strains) was found to be the most abundant type among the P. rettgeri.
3. The isolated strains were almost as predicted by the law of Edward-Ewing. The strains were individually isolated on performing the tests of H_(2)S, Ornithine, Urea, and Inositol on the 25 P. rettgeri. The results of the Indol reactions revealed 4(16.%) negative strains, 6(24%) Rhamnose negative strains, and 3 negative strains of Phenylalanlne and one nesative strain of Citrate.
4. All 2 strains were found to be susceptible to Gentamyoin and Nalidixic Acid. Three(9.4%) strains were found to be resistance to Sulfamethoxazole and Streptomycin ; seven(22%) to Cabenicillin ; 9(36%) to Chlorampheniccol ; twenty-two(69%) to Ampicillin ; twenty-four(75%) to Cephalothin ; twenty-six(81%) to Colistin ; twenty-nine(91%) to Erythromycm ; thirteen(94%) to Tetracycline, and all 32 to Penicillin. The average rate of resistance was found to be 48.2 percent.
5. Multi-resistant strains were distributed as follows :
Four-multi-resistant strains : 2 strains
Five-multi-resistant strains : 13 strains
Six-multi-resistant strains : 10 strains
Seven multi-resistant strains : 5 strains
Eight-multi-resistant strains ' 2 strains
