2001년 2월 12일경, 경남 서생 소재 한 넙치 양식장에서 임상적으로 궤양, 체색흑화 및 복수증을 동반하는 질병이 발생하였다. 보름 동안 한 탱크에서만 총 4백미 중 약 5%가 발병하였으며 하루에 10미 미만으로 폐사가 있었다. Ampicillin 투여 후 폐사량이 줄어들었다. 폐사가 일어나고 있던 기간의 수온은 10~13$^{\circ}C$, 염분농도는 31~33$ extperthousand$이었다. 임상적으로 이상 소견을 나타내는 넙치를 채집하여 간, 비장 및 체신에 대해 Nacl(1.5%) 첨가 TSA에 1mm 이하의 연한 아이보리색의 세균 집락이 느린 속도로 자랐다.

The importance of the gut microorganism in the termite, Reticulitermes Speratus kyushuenesis Morimoto, was estimated by feeding with several antibiotics. Antibiotics which killed the bacterium, but not the fungi (Ampicillin, Kanamycin, Erythromycin), or killed both the microorganismw (Cephaloridine, Tetracycline) reduced the life span of the termite from 245 days to about 15 days. On the other hand, some antibiotics, penicillin and pimaricin, did not greatly reduce the life span of the termite.

Antibiotic resistance patterns were determined for 14 strains of Staphylococcus aureus isolated at a hospital in Pusan during summer in 1989. Resistance to chloramphenicol or clindamycin was recorded in 100% of strains. Resistance to the other compounds tested was as follows: tetracycline 86%, gentamicin 79%, tobramycin 71%, kanamycin 71%, erythromycin 57%, ampicillin 57%, methicillin 50%, streptomycin 29%, cephalothin 29%, and trimethoprim 21%. All strains were sensitive to vancomycin and rifampicin. All strains showed multiple resistance to more than 3 antibiotics.

Degradation of aromatic compound by Pseudomonas mendocina BCNU 154 has been investigated. The microorganism utilizes xylene, toluene, nitrobenzene, ethylbenzene and cumene. This strain is tolerant to some heavy metals, such as Mn, Cu, Si, and Mo, and resistant to some antibiotics, such as vancomycin, chloramphenicol and ampicillin. The metabolic pathway of toluene in Pseudomonas mendocina BCNU 154 is also elucidated.

The adhesion of hydrocarbon degrading bacteria(HDB) differing in surface hydrophobicity was investigated. Cell wall hydrophobicity was modified chemically and physiologically. Modified adhesion deficient mutant of HDB was selected in a soil column assay Physiologically and chemical modification increased cell surface hydrophobicity. Cell surface charcteristis including BATH and zeta potential were measured. Physiological modification using ampicillin was not stable, but chemical modification was stabel. Hydrocarbon degrading potential was measured for modified and unmodifed HDB.

Modified adhesion deficient mutant of HDB was selected in a soil column assay. Physiologically and chemical modification increased cell surface hydrophobicity. Cell surface characteristics including BATH and FTIR were measured. Physiological modification using ampicillin was not stable, but chemical modification was stable. Hydrocarbon degrading efficiency was measured of TPH modified and unmodifed HDB.

This study was designed to compare the Antimicrobial effect of the several antibiotics on anaerobes. After Bacteroides gingivalis was streaked on the surface of Blood agar plates, antibiotic discs were applied and cultured 5 days anaerobically. Following results were obtained 1. All of the examined antibiotics had antimicrobial activity with varying degree. 2. The antimicrobial activity of Clindamycin and Tetracycline was larger than any other antibiotics. Vancomycin showed the lowest activity. Erythromycin and Ampicillin showed the moderate antimicrobial activity. (P<0.05)

Several bacteria and yeasts were isolated from soil and characterized for the development of functional probiotics which can be used as a livestock feed additive. From the soil, the microbial strains which have acid/bovine resistance, antibiotics resistance and high stability, were isolated. Most strains selected were very tolerable against acids and very stable in a broad range of pH. Some strains could survive 100% at pH 2.5. The growth of the strains was not affected in the presence of bile acid, pathogenic E. coli and several antibiotics such as tetracycline, nisin, kanamycin, streptomycin, ampicillin. Acidogenic capability test showed that all the strains can produce acids. The hydrolytic activities were analysed for amylase, protease, lipase and cellulase to decompose various organic compounds. All the strains were found to be gram negative, round type, non-kinetic and the color is yellow or white.

The authors made a study on the bacteriological identification about unidentified strains which were roughly screened by local health center, which an epidemic diarrhea was outbreak at Ham Yang Gun, Kyeongsang-Namdo in July 1971. And the authors made an attempt to bacteriological Identification, serotyping with slide agglutination, and determination of the susceptibility of identified strains to various chemotherapeutic agents. The results Were obtained as follows: 1. The isolated strains identified Shigella flexneri type 2b(2 strains) and Salmonella paratyphi B(4 strains). 2. Sensitivity test using with three concentrations chemotherapeutic agents(Paper disk used; Eiken chemical Co., Tokyo, Japan): (1) Shigella flexneri type 2b isolated strains were sensitive to kanamycin, colistin(100%) and penicllin(50%) respectively, but resistant to erythromycin, oleandomycin, leucomycin, chloramphenicol, tetracycline, dihydrostreptomycin and sulfadimethoxin(100%) respectively. (2) Salmonella paratyphi B isolated strains were sensitive to chloramphenicol, tetracycline, dihydrostreptomycin, kanamycin, sulfadimethoxine(100%) and colistin(50%) respectively, but resistant to penicillin, erythromycin, oleandomycin and leucomycin(100%) respectively. 3. Sensitivity test using with multodisk urinary code(Paper disk used; Oxoid, London): (1) Shigella flexneri type 2b isolated strains were sensitive to Bactrim, ampicillin, nitrofurantoin, nalidixic add and gentamicin(100%) respectively, but resistant to chloramhpenicol, tetracycline, sulfadiazine and Fanasil(100%) respectively. (2) Salmonell paratyphi B isolated strains were sensitive to Bactrim, chloramphenicol, ampicillin, nitrofurantoin, tetracycline, nalidixic acid, gentamicin(100%) and sulfadiazine(50%) respectively, but resistant to Fanasil(100%) and sulfadiazine(50%) respectively.
