겨울철 산란육성계와 브로일러에서 장염, 미숙변, 연변, 계사과습 등으로 증체, 폐사, 도태율이 증가하여 생산성이 저하되며 산란성계 편입 후에도 능력을 최대한 발휘하지 못하여 고심한다. 여름철에는 콕시듐증이 문제이지만 겨울철은 방한시설에 치중하다보면 장염성 살모넬라증을 일으켜 눈에 보이지 않게 손실을 보게 된다. 닭에서 상기원인체인 살모넬라증은 인수공통전염병(人獸共通傳染病)의 하나로 닭은 물론 사람에게도 오염된 닭고기, 계란을 먹고서 때때로 식중독 증상을 일으킨다. 아울러 닭에서도 과습고온 사육시 연변, 하리, 장염, 소화장해 등으로 생산성 저해 소화기 질병을 일으킨다. 이 달에는 본 질병의 근본원인체인 살모넬라 장염에 대하여 기술한다.

여름철에 빈번히 발생하는 세균성 식중독의 주요 원인세균의 하나인 장염 Vibrio 균에 대한 연구 보고는 국내외적으로 많지만 우리나라에서는 수온이 $10^{\circ}C$ 이하인 겨울철에는 일반적으로 검출되지않는다고 알려져 있다. 따라서 이 균의 활동성을 알아보기 위하여 부산 용호만 일대에서 평균기온이 $0^{\circ}C$ 부근인 1978년 1월과 2월에 해수, 저질패류를 채취하여 시험한 결과를 보고하는 바이다. 1) 해수 500mι씩을 membrane filter paper로 처리하여 증균배양한 결과 10회중 3회에서 장염 Vibrio 균이 검출되었다. 2) 저질의 경우는 8회중 7회, 패류의 경우에서는 10회중 2회에서 이 균이 분리되었다. 3) 결론적으로 장염 Vibrio 균은 연안의 저질에서 활동하는 사실을 알 수 있었으며, 여름철이 아닌 겨울철에도 생선어패류에 있어서는 장염 Vibrio 균에 의한 식중독을 완전히 배제할 수 없음을 알수 있었다.

Purpose: Campylobacter species are common causes of bacterial enteritis. There is limited knowledge on its prevalence and clinical features because of its fastidious culture conditions. The purpose of this study was to identify the clinical features of Campylobacter enteritis in children. Methods: We obtained stool specimens from patients diagnosed with acute gastroenteritis in the Department of Pediatrics, Nowon Eulji Medical Center (NEMC) and identified the pathogens by performing cultures or polymerase chain reactions (PCR). We retrospectively reviewed the medical records of patients with Campylobacter enteritis at NEMC between January 2012 and December 2017. Results: Overall, 123 patients were diagnosed with Campylobacter enteritis (60 by culture and PCR in EnterNet and 110 by multiplex PCR). The median (interquartile range [IQR]) age of patients was 12 years (IQR, 8 to 16 years). The disease occurred all year round, but 69.9% from June to September. Symptoms included diarrhea (97.6%), fever (96.7%), abdominal pain (94.3%), vomiting (37.4%), and headache (34.1%). Compared with other treatments, treatment with azithromycin was associated with a shorter hospitalization period (P<0.05). Conclusions: Campylobacter enteritis is common during summer and mostly infects adolescent patients. It causes severe abdominal pain and fever preceding the onset of diarrhea. Prompt diagnosis and appropriate use of antibiotics reduces the duration of the disease.

This study analyzed the related factors affecting to perceived gastritis or perceived enteritis for 11,753 Korean high school seniors who participated in the 2009 Korea Youth Risk Behavior Web-based Survey (KYHRBWS). Of the subjects, 5,685 (47.6%)were male and 6,068(52.4%) were female and 8.7% of the students responded that they had suffered from gastritis or enteritis for a long time and the females had a slightly higher attack rate of gastritis or enteritis. Survey logistic regression models and decision tree analysis were used to calculate odd ratios and 95% confidence intervals. As a result, there was affecting to their stress and health behaviors in the risk of gastritis and enteritis, and that their lower level perceived health, smoking, heavy drinking or starting drinking before they were 13 years old and a higher level of perceived stress significantly affected the risk of gastritis or enteritis in the subjects(p<.001).

Recently canine parvovirus(CPV) enteritis had been controlled successfully by the use of low-passage high titer modified live CPV vaccines. However, outbreaks of CPV enteritis have been continued in Korea. In this study, we carried out epidemiological investigation on the recent outbreaks of CPV enteritis of dogs and determined the potential prognostic factors affecting the survival of dogs. The total of 140 dogs diagnosed for CPV enteritis were statistically analysed. The majority of dogs were from 6 to 18 weeks of age and were not vaccinated or incompletely vaccinated. There were significant difference in the survival rate between male and female dogs with CPV enteritis and among the age groups(p<0.05). Moreover, there was significant difference in the survival rate of dogs between HI titer <80 group and HI titer 160 group(p<0.05). The majority of dogs had a history of diarrhea, vomiting, lethargy and dehydration. It was considered that recent outbreak of CPV enteritis in Korea caused by the failure of vaccination and/or by the inadequate antibody responses to CPV vaccines. Prophylactic measures should include isolation of young dogs from the dog population until the vaccination can be expected to provide protection.

V. parahaemolyticus causes waterborne and foodborne disease such as acute diarrhea. In this study, V. parahaemolyticus isolates from seawater, fish tanks, and distributed fishery products in Jeju were investigated for potential toxin or species-specific genes (tdh, trh, tlh, and toxR) using RT-PCR and their genetic characteristics were analyzed using Pulsed-field gel electrophoresis (PFGE). Overall, V. parahaemolyticus of 90 strains (36.7%), including 33 strains from seawater, 8 strains from fish tanks, and 50 strains from fishery products, were isolated from 245 samples. All V. parahaemolyticus strains did not detect the tdh gene, whereas all strains detected tlh or toxR genes. In addition, trh genes were detected in 3 strains from seawater and 1 strain from fishery products. Monthly quantitative testing of seawater revealed that V. parahaemolyticus was positively correlated with water temperature. The 90 strains of V. parahemolyticus obtained in this study showed by gene homology between types, ranging from 64.0-97.3%. Among these, thirteen types showed 100% homology between genes. These results indicate that continuous monitoring is needed to facilitate food poisoning epidemiological investigations because some isolated V. parahaemolyticus strains harbored toxin genes and V. parahaemolyticus strains isolated from seawater, fish tanks, and distributed fishery products showed genetic similarity.

장염의 원인은 매우 다양한데, 식중독과 같은 각종 바이러스성 감염과 세균 감염 등으로 인한 감염성 장염이 흔하며, 크론씨병, 궤양성 대장염과 같은 만성 질환도 있다. 주로 나타나는 증상은 복통과 설사이며 열이 동반되는 경우도 있다. 복통은 정확히 위치를 알 수 없는 묵직한 통증이 가장 흔하며, 묵직한 통증으로 시작하여 뒤틀리는 듯이 심하게 아픈 통증으로 진행하는 경우가 흔하다. 설사는 적게는 하루에 2~3회에서, 많게는 20여 회가 넘는 경우까지 그 빈도가 다양하다. 대장이 감염된 경우 변에 코와 같은 점액이 많이 섞여 나오고, 소장이 감염된 경우에는 점액이 별로 섞여 나오지 않는다. 주로 6개월~24개월 사이의 아이에게 잘 발생하며, 춥고 건조한 늦가을부터 겨울철(10월~1월)에 가장 많이 발생하는데, 우리나라에서는 시기에 관계없이 발생하기도 한다.

To assess the risk of V. parahaemolyticus infection caused by consumption of raw oysters in Korea, contamination levels during the retail-to-table route of oysters was modeled to predict V. parahaemolyticus growth based on temperature and time. The consumed amount data of the KNHANES and the standard recipe of RDA were applied. A consumption scenario for exposure assessment was developed and combined with a Beta-Poisson dose-response model. The estimated probability of illness from consumption of pathogenic V. parahaemolyticus in raw oysters during three separate months (April, October, and November) was $5.71{\times}10^{-5}$ (within the 5th and 95th percentile ranges of $2.71{\times}10^{-8}$ to $1.03{\times}10^{-4}$). The results of the quantitative microbial-risk assessment indicated that the major factors affecting the probability of illness were the initial contamination level at the retailer, the consumed amount, the prevalence of pathogenic strains [tdh or trh genes], and exposure temperature and time.

The distribution of V. parahaemolyticus was surveyed from various kinds of shells in Kunsan Bay from July to September, 1987. 1be morphological, biochemical and serological characteristics of the isolated strains were studied. The results were as follows: 1. 41 strains were isolated from 1,350 specimens of shells (Crassostrea gigas, Tapes philippinarum, Meretrix Iusoria) 2. The isolation rates of V. parahaemolytieus were 3% in July, 3.8% in August, and 2.2% in September, respectively. 3. V. parahaemolytkus was more frequently isolated from Kunsan (20 strains) than Bideukgi (12 strains) and Gae Hwa-do (9 strains). 4. V. parahaemolyticus was more frequently isolated from C gigas (23 strains) than other shells. 5. Kanagawa hemolysis reactions were all negative. 6. 6 Strains positive to K pooled antiserum included K IV, K V, K VI and K vn type.
