ORT(Ornithobacterium rhinotracheale) 감염증이란 닭과 칠면조에서 급성 호흡기 증상과 함께 복기낭에 노란색 삼출물 저류가 특징적인 세균성 전염병이다. ORT감염증은 1991년 남아프리카에서 성장지체와 호흡기증상을 보이는 28일령의 육계에서 최초로 분리된 이후 네덜란드, 독일, 폴란드 등 여러 나라에서 발생 보고되었다.

세균성 감염 관절염은 활액막염(synovitis)으로서 활액막에 염증이 생겨 발병하게 된다. 일반적으로 관절염과 건초염(tenosynovitis)은 동시에 발생하는 경향이 있으며, 관절염이 발병한 브로일러 종계는 결국 도태시킬 수밖에 없다.

살모넬라 갈리나륨(Salmonella gallinarum)이 원인체인 가금티프스는 모든 품종의 닭에서는 물론이고 어린 일령의 병아리에서부터 산란중인 성계에 이르기까지 전 일령의 닭에서 높은 폐사를 일으키는 세균성 질병으로 우리나라뿐만 아니라 세계적으로 발생되고 있는 질병이다.

곰팡이성 위염은 곰팡이의 감염에 의해 산발적으로 발생하는 질병인데 곰팡이 낀 사료나 건초를 먹을 경우 발생하고 Candida albicans, Mucor, Rhizopus, Absidia, Morteierella 및 Aspergillus 같은 곰팡이가 원인이 된다. 이런 곰팡이성 위염은 세균성 내독소혈증, 패혈증, 스테로이드제제나 항생제의 장기간 사용 시에 곰팡이에 대한 저항 형성하여 점막층과 점막하직 및 장막층까지 약화시켜 폐사에 이르게 하기도 한다. 국내에서도 곰팡이에 의한 괴사성 위염으로 폐사한 예가 있어 사례를 보고한다.

Purpose : Long term hospitalized infants in neonatal intensive care units(NICUs) are prone to systemic infection. It is important to differentiate systemic candidiasis from systemic bacterial infection early in the course. Thus, in this study, we have compared clinical characteristics of systemic candidiasis and systemic bacterial infection, in premature low birth weight infants. Methods : Retrospective chart review of the medical records of 20 patients with systemic candidiasis and 23 patients with systemic bacterial infection was performed. Results : Among the risk factors of systemic candidiasis, total parenteral nutrition(TPN), the use of broad spectrum antibiotics, central catheter insertion, endotracheal intubation and the use of H2 blockers were more frequent in neonates with systemic candidiasis than neonates with systemic bacterial infection. Apnea with bradycardia developed more frequently in neonates with systemic candidiasis compared with systemic bacterial infection(75% vs 39%). In laboratory findings at symptom onset, seven cases(35%) of systemic candidal infections and two cases(9%) of systemic bacterial infections showed leukopenia and thrombocytopenia(P=0.03). Blood was the most frequent isolation site of candida and bacteria. Conclusion : In neonates with systemic candidiasis, apnea with bradycardia, pneumonia and thrombocytopenia were prone to develop more frequently. The use of TPN, antibiotics and central catheters was strongly associated with systemic candidiasis. Empirical treatment with antifungal agent should be considered in critically ill neonates with above findings.

The bloody watermelon exhibiting dark red and fermentation off-flavor results in a great economic loss. As an effort to clarify the cause of the bloody watermelon, relationship between the fermentational off-flavor and the presence of endophytic bacteria was studied. The number of endophytes was 2.2-37.0 ${\times}10^3$ cfu/g fw (fresh weight) in normal watermelons, compared to 1.26-1.75 ${\times}10^6$ cfu/g fw in bloody ones. Seventeen bacteria among 56 isolates from bloody watermelons could induce bloody watermelons. The bacteria responsible for bloody watermelons were mainly Gram negative: aerobic Pseudomonas spp and some anaerobic bacteria. The results in this study strongly suggested that the bloody watermelons were produced by abnormal fermentation and growth of endophytic Gram negative bacteria.

A gas-circulating bioreactor was used for enrichment of autotrophic methanogens. Mixture of hydrogen and carbon dioxide (5:1) was used as a sole energy and carbon source. Anaerobic digestive sludge isolated from wastewater treatment system was inoculated into the gas-circulating bioreactor. The enrichment of two chemolithotrophic methanogens, Methanobacterium curvum and Methanobacterium oryzae was accomplished in the gas-circulating bioreactor. The enriched bacteria were cultivated in a bioreactor equipped with hollow-fiber hydrogen-supplying system (hollow-fiber bioreactor), and a hybrid-type bioreactor equipped with hollow-fiber hydrogen-supplying system and electrochemical redox control system. The methane productivity was maximally 30% (V/V) in the hollow-fiber bioreactors and 50% (V/V) in the hybrid-type bioreactor.

To study the diversity of heterotrophic bacteria isolated from intestine of starfish, Asterias amurensis, we collected starfishes from the coastal area near Jangheung-Gun, Jeollanam-Do, Korea during July, 2000. Population density and bacterial diversity in the intestine of starfish were measured. The results were as follows; The population densities of heterotrophic bacteria in the intestine of starfish were 8.65${\pm}$0.65${\times}10^3\;dfu\;g^{-1}$. Gram positive bacteria occupied 59% among 29 isolates. The community structure of dominant heterotrophic bacteria in the intestine of starfish consisted of Bacillaceae in the low G+C gram positive bacteria subphylum, Microbacteriaceae in the high G+C gram positive bacteria subphylum, and Alteromonadaceae in ${\gamma}$-Proteobacteria subphylum. Among eight strains of Bacillus spp., three strains showed more than 97% identity, but five strains showed about 90% identity with type strain on the basis of partial 16S rDNA sequence.
