Gwang-ju and Jeol-la city and medium-sized hospitals in the material with a cotton swab and rub evenly Radiology selection cassette, a handle, Apron of the imaging apparatus having the most contact with patients from July 2016 to August 2016 as a target in place and special studios 6, and saline solution will placed in a test tube containing. The swab sample was diluted 1,000 times, you can see the bacteria and the intestinal bacterial selective medium Trypticase Soy Agar (TSA), Muller-Hinton Agar (MHA), Eosin-Methylene Blue (EMB), ENDO(BD, NJ, USA) then incubated smear to. In the incubator (incubator, SANYO, Japan) was observed after incubation of bacteria and counting the total number of bacteria also Colonies (colony) suspected intestinal bacteria were isolated and cultured on KIA medium (BD, NJ, USA). As a result, it was found that this came Gram positive Coccus A hospital handle the F hospital, from the C Gram positive Coccus cassette and handle the F hospital. The striking yellow coloring Staphylococcus aureus 110 agar (STA 110) in the medium sample, but it is suspected staphylococcal Coccus to the final identification in the laboratory is not a single specimen of the two samples from Gram positive Coccus biochemical identification Identification Kit is an API could not, it was thought to be non-Staphylococcus aureus was cultured on blood agar suggesting that (BAP) blood of dance. Dynamic tests were conducted biochemical API kit of the two samples were identified from Gram positive Coccus bacteria Escherichia coli (E. coli) is F hospital cassette was confirmed Eenterobacter cloaca in A hospital possession. Did not aggregate O-26, O-111, O-157 and the serum test was conducted in the laboratory from the E. coli F cassette hospital.

  • 의료용 초음파 장치의 프로브에서 일반적으로 검사자와 피 검사자가 접촉이 가장 많은 부위 중 무작위로 3부분을 임의로 선정하여 프로브에 상제하고 있는 병원균을 검출하여 병원균의 종류와 균수를 알아보았다. 또한 검출된 병원균에 대하여 프로폴리스 추출액, 소독용 에탄올, 소독용 티슈를 이용하여 각 각 소독 후 병원균의 사멸정도를 정량적으로 알아보았다. 그 결과 선형 프로브에서는 S. aureus(32.3%), Bacillus spp.(26.1%), Micrococcus spp.(21.5%), CNS(20%)가 검출되었고, 볼록형 프로브에서는 S. aureus(26.2%), Strepto coccus(24.3%), Entero coccus(19.5%), Micrococcus spp.(15.5%), CNS(14.6%), 부채꼴 프로브에서는 S. aureus(24.1%). Micrococcus spp(24.1%), Entero coccus(20.7%), Strepto coccus(17.2%), CNS(13.8%)순으로 검출되었다. 검출된 병원균을 대상으로 소독을 위해 선정한 3가지 소독액을 이용하여 소독한 결과 소독용 에탄올의 경우 대부분의 병원균을 사멸시켰으며 최소 91.3 %에서 최대 100 %의 사멸효과로 가장 큰 소독 효과가 있는 것으로 분석되었다(P>0.05). 또한 프로폴리스 추출액과 소독용 티슈의 경우 모든 소독용 에탄올에 비해 소독효과는 낮았으나 소독효과에는 통계적으로 유의한 것으로 분석되었다(P>0.05). 실험결과를 보면 대부분의 초음파 프로브에서 다양한 병원균이 검출되었으며, 소독용 에탄올, 소독용 티슈의 소독효과가 있었으며 특히 프로폴리스 추출액을 이용한 소독도 병원균 사멸에 효과가 있는 것으로 분석되어 향 후 검사자와 피검사자의 접촉이 많은 초음파 프로브 소독 시 적용한다면 감염예방에 있어 도움이 될 것으로 사료된다.

  • Microbial communities were analyzed in an anaerobic/aerobic sequencing batch reactor (SBR) fed with glucose as a sole carbon source. Scanning electron microscopy (SEM) showed that tetrad or cuboidal packet bacteria dominated the microbial sludge. Quinone, slot hybridization, and 165 rRNA gene sequencing analyses showed that the Proteobacteria beta subclass and the Actinobacteria group were the main microbial species in the SBR sludge. However, according to transmission electron microscopy (TEM), the packet bacteria did not contain polyphosphate granules or glycogen inclusions, but only separate coccus-shaped bacteria contained these, suggesting that coccus-shaped bacteria accumulated polyphosphate directly and the packet bacteria played other role in the enhanced biological phosphorus removal (EBPR). Based on previous reports, the Actinobacteria group and the Proteobacteria beta subclass were very likely responsible for acid formation and polyphosphate accumulation, respectively, and their cooperation achieved the EBPR in the SBR operation which was supplied with glucose.

  • The resistances to multiple antibiotics of strains of Gram-positive Staphylococci. methicillin-resistant Staphylo coccus aureus (MRSA), are now significant clinical problem. One of the major efforts of our laboratory has been the search and design and synthesis of novel lead compound for the purpose of obtaining highly potent anti-MRSA drug. Towards this end, we have recently reported the isolation of a potent anti-MRSA drug. (omitted)

  • Serratia marcescens characterized by the ability to produce red pigments inhabits various ecological niches. A strain Serratia marcescens PYU was isolated from abalone (Haliotis discus) collected at the West Sea in Korea. The isolated strain was gram-negative, motile, rods like coccus, oxidase-negative, and catalase-positive; and formed red pigment. S. marcescens PYU was grown in the presence of 0~10% (w/v) NaCl, at pH 4~9, and at $10{\sim}40^{\circ}C$. The strain PYU produced red pigment, and the extracted pigment showed antibacterial activity against Streptococcus iniae and Lactococcus garviae which has been known as an important fish pathogens. Further studies are underway to elucidate the direct relationship between the red pigment and antibacterial activity.

  • The isolation and identification of bacteria from freshwater plant root system were performed. Twenty four different strains were identified by microbiological identification system. Gram negative bacteria were isolated three times more than Gram positive ones. The ratio of rod and coccus was 11:1. The similarity above 0.5 was 37.5% from the tested samples in identification. Among these isolated bacteria, three dominant strains Pseudomonas cepacia JH10, Xanthomonas maltophilia JH12, Aeromonas salmonicida JH13 were selected to investigate biochemical properties and optimal growth conditions. These strains reached maximum growth after 24-36 hr of incubation in peptone broth, and their optimal temperature was 28$^{\circ}C$ and that of pH was between 7 and 8.

  • Antibacterial effects of the water-soluble extract of Ulmus pumila L. on Staphylococcus aureus and Escherichia coli were studied by cylinder plate dilution method. The cells of S. aureus and E. coli treated with the extract were comparatively examined by scanning and transmission electron microscopies for their morphological features. The normal cells of S. aureus and E. coli showed thypical coccus and rod shapes, respectively, but the cells of S. aureus treated with the extract showed rough surface structures with many granular protrusions and were destroyed to form ghost cells by liberating their cytoplasmic components. E. coli cells treated with the extract were destoryed without enlarging in size and producing granules on their surfaces.

  • 수출용 심비디움에 발생하는 해충의 종류와 해충관리 현황을 알아보고자 국내 주요 재배단지 10개 지역 45농가를 대상으로 조사를 실시하였다. 농가에서 채집된 해충의 종류는 응애류(20농가), 깍지벌레류(6농가), 민달팽이류(6농가), 총채벌레류(8농가), 진딧물류(5농가) 노린재류(1농가) 등이었다. 채집한 해충은 현미경을 이용하여 동정한 결과 점박이응애(Tetranychus urticae Koch), 대만총채벌레(Frankliniella intonsa Trybom), 난초핀깍지벌레(Pinnaspis aspidistrae Signoret), 민달팽이(Incilaria confusa Cockarel), 썩덩나무노린재(Halyomorpha brevis Walker), 복숭아혹진딧물(Myzus persicae Sulzer), 목화진딧물(Aphis gossypii Glover), 무화과깍지벌레(Coccus hesperidum Linnaeus)와 소형달팽이류 1종으로 나타났다. 총채벌레 산란피해로 의심되는 증상의 정확한 동정을 위해 rDNA의 ITS2 부위를 PCR-RFLP 한 결과 아까시총채벌레(Thrips flavus Schrank)와 파총채벌레(Thrips tabaci Lindeman)로 확인되었다. 따라서, 수출 심비디움을 재배하는 농가에서는 이러한 해충들에 대한 종합적인 방제대책을 수립하여 실천하는 것이 필요할 것으로 생각된다.
