뇌척수액(腦脊髓液)에서 분리(分離)한 Listeria monocytogenes
오흥백 ( Hung Baek Oh ),노성근 ( Sung Keun No ),김종열 ( Jong Yol Kim ),조용현 ( Yong Hyun Jo ) 대한임상검사과학회 1980 대한임상검사과학회지(KJCLS) Vol.12 No.1
1. Listeric meningitis or septicemia is sometimes a secondary infection in debilitated patients with diabetes, neoplastic disease and alcoholism, and about half of the cases are infectious. 2. The organism were recovered from cerebrospinal fluid of a patient who had acute suppurative meningitis with age of 45 on march 13, 1979. 3. The strain produced a narrow zone of hemolysis on blood agar, and showed gram positive short bacilli on Gram``s stain, and grew slowly in thioglycollate fluid medium at 4℃ 4. The typical biochemical properties are motility positive, catalase positive, MR-VP positive, indol not produced, urea not hydrolyzed, but esculin hydrolyzed. The carbohydrate fermentations are the same as that of the typical L. monocytogenes as shown in Table 1. 5. L. monocytogenes is susceptibe to Cephalothin, Gentamycin, Kanamycin, Streptomycin, Amikacin, Dibekacin, Lincomycin, Erythromycin, Carbenicillin, Sulbenicillin, Minocin, and Oxytetracycline, and intermediate to Ampicillin and Penicillin, but resistant to Cloxacillin. 6. L. monocytogenes was identified as serotype 4b, with help of Dr. Nagai who has been working for Listeric research at College of Medicine , Sapporo University , Japan.

Vibrio parahaemolyticus의 분리 및 그 M.I.C.에 대한 고찰
오흥백 ( Hung Baek Oh ),조명원 ( Myung Won Jo ) 대한임상검사과학회 1979 대한임상검사과학회지(KJCLS) Vol.11 No.1
1. Vibrio Parahaemolyticus was first isolated from a victim of food poisoning by Dr. Fujino, in 1951. It has been reported that about 50-70per cent of the cases of bacterial food poisoning in Japan have been caused V. parahaemolyticus, mostly Prevalent between june and September. 2. Of total 16 strains isolated, 15 strains were from 21 food poisoning patients and 1 strain from salt dressed crab. 3. All of the rectal swabs were streaked`` on T.C.B.S. (Thiosulfate Citrate Bile salts Sucrose) agar plates, and enriched in to 1% peptone water with 3% sodium chloride. On T.C.B.S. agar plate, the colonies showed bluish green color and smooth withmedium size, and no vibrio colony was found on MacConkey, S.S. and blood agar plates. The biological characteristics and phisiological properties were shown in Table 4. 4. All of V. parahaemolyticus were highly susceptible to chloramphenicol and tetracycline group antibiotics (oxytetracycline and Minocin) by the dilution method with of M.I.C. 2mcg/ml. or less. They were resistant at 16-356mcg/ml. to penicillin group antibiotics (Ampicillin and sulbenicillin), and highly resistant to aminoglycoside group antibiotics (kanamycin, Streptomycin and Dibekacin) at M.I.C. 32mcg/ml. or more, while slightly to gntamycin with M.I.C. of 8mcg/ml. or more. They were also moderately resistant to cephalosporin antibiotic with M.I.C. of 32mcg/ml. or more. 5. Of total 16 strains isolated, 7 strains of K-3, 4 strains of K-18, 2 strains of K-22, 1 strain of K-56 and unty peable 2 strains were detected. Although untypeable 2 strains were not agglutinated with any K-type multiple serum , their biological characteristics were same as that of the typical Vibrio parahaemolyticus. It suggests that these 2 strains would be new K type.

임상(臨床) 재료(材料)에서 분리(分離)한 포도당(葡萄糖) 비발효균(非醱酵菌)
오흥백 ( Hung Baek Oh ),김대식 ( Dae Sik Kim ),길영철 ( Young Chul Kil ),최승구 ( Seng Koo Choi ),이상국 ( Sang Kook Lee ) 대한임상검사과학회 1982 대한임상검사과학회지(KJCLS) Vol.14 No.1
Nonfermentative bacilli (NFB) habe been thought as harmless bacteria when cultured from human specimen, though many have shown to be opportunistic pathogens of human. NFB were often confused with other pathogens in recognition and identification in clinical microbiology practlce. Of 1272 NFB cultures, 12 species identified from c1inical specimens during the period from August 1981 to July 1982. The identification of the species was performed on the oxidation and fermentation (O.F.) media with special tests. The followings were the results obtained. 1. Pseudomonas aeroginosa was the most prevalent species of NFB with 46.3% of all strains isolated, Acinetobacter anitratus (19.3%), followed by Pseudomonas cepacia (19%) , Achromobacter (5.4%), and Pseudomons maltophilia (3.4%). 2. NFB identified were cultured from pus (27.2%), urine (25%), sptum (21%) in order of frequency. 3. The most frequently isolated species of XFB isolated from blood was Pseudomnas cepacia (18 strains) and Achromobacter (9 strains) in next folloued by Pseudomonas aeruginosa (8 strains), Pseudomonas putida (3 strains), and Pseudomonas maltophilia (2 strains).

We analysed the pattern of isolates and the antibiotic susceptibility of 611 salmonella strains in Kyung Hee University Hospital from 1980 to 1986 and the clinical characteristics of 22 salmonella enterocolitis caused by S. typhimurium in 1986. The results are as follows; 1) The isolation pattern of salmonellae (1980-1986) showed that the incidence of group A salmonella and S. typhi decreased and that of group D increased. 2) The isolation rate of group B salmonella was markedly increased in 1986 compared with that in 1980-1985. Group B salmonella infections occur with greatest frequency from June through August, 1986. 3) The isolation rate of salmonella group B and group C from stool were 81% and 59% respectively. However, the isolation rate of salmonella in general from blood (63%) was higher than that from stool (29%). 4) In antibiotic sensitivity test of 36 isolates of group B salmonella, 13 of 13 isolates from 1980 to 1985 showed no antibiotic resistance. But 18 of 23 (78%) isolates in 1986 showed the resistance to chloramphenicol, ampicillin and carbenicillin. 5) Group B salmonella isolated in 1986 was sensitive to aminoglycoside, cephalothin, pipemidic acid and trimethoprim-sulfame thoxazole. 6) The serovar of group B salmonellae isolated in 1986 was salmonella typhimurium. 7) The main clinical manifestations of S. typhimurium enterocolitis were diarrhea and fever.
