Epizootic streptococal infction is one of the common disease in guinea pig. We have confirmed 54 case of epizootic streptococal infection in guinea pig by histopathology and epidemiology. Grossly infection is characterized by the presense one to several enlarged lymph nodes particularly of the mandible cervical lymph nodes and accompanied by pleuropneumonia. Histologically there were lymphadenitis with abscesses surrounded by loose connective tissue fibrinopurulent pneumonia pleuritis myocarditis pericarditis and peritonitis. Epidemiological survey revealed that mortality was high in young adult female(15.1%) and changeable weather season such as spring and fall. From findings it was suggested that epizootic streptococal infection of guinea pig begin to infect in breeding colony around weaning period and died from that infection at animal facility during the quarantine period.

Water temperature is a key environmental factor controlling the epizootics of viral diseases in fish. High water temperature is associated with the rapid spread of rock bream iridovirus (RBIV) disease and with high mortality of RBIV infected fish. Although protection of fish against iridoviral disease by active immunization has been reported, little information is available concerning whether fish survived from an epizootic of iridoviral disease can naturally acquire resistance against the viral disease. In the present study, we have demonstrated that juvenile rock bream, which survived from a natural epizootic of RBIV, acquired resistance against recurrence or reinfection of RBIV, and this resistance was established during the subsequent low water temperature period. Furthermore, the possible involvement of the adaptive humoral immune response in the resistance of the juvenile rock bream was suggested by in vivo neutralization experiment.

본 연구는 한국산 양식 가물치에 큰 피해를 주는 출혈성 궤양증의 원인과 병리를 연구할 목적으로 수행되었다. 가물치의 출혈성 궤양증은 그 원인이 세균성이었고 궤양 및 장기로부터 분리된 Aeromonas veronii 가 주원인균이었다. A veronii 를 건강한 가물치의 피하에 인공 접종한 결과 양식 가물치에서 관찰된 병증과 유사한 궤양을 유발시켰다. 초기 증세는 주사부위를 중심으로 피부에 붉은 반점이 나타났고, 점차 확대되면서 피부가 탈락되고 출혈이 수반되었다. 곧이여 근육괴사가 진행되어 조사된 반대쪽에 구멍이 뚫렸다. $10^{5}$/CFU/0.25 ml 의 세균은 복강주사시 72시간이내에 시험개체의 50%가 치사되었다. 본 균은 cephalothin, chlorampenicol, gentamicin, tetracyline 등의 항생제에 감수성을 나타내었다.

우리나라 뉴캣슬병 (ND) 면역상의 문제점을 파악하고 명확한 예방접종지침을 제시하는 목적의 일환으로 우선 ND 유행이 극심하였던 지역의 일반양계농장에서 사육되는 건강면역군의 예방접종경력과 혈구응집억제항체가(HI 가)를 조사하여 야외에서 실시된 ND예방접종결과에 따르는 면역효과를 간접적으로 파악하는 한편 동일지역 내에서 ND발생계군과 비발생계군에 대한 예방접종경력과 발생계군의 피해상황을 조사함으로서 야외에서 실시한 ND예방약의 응용방법과 본병발생과의 관계를 조사한 추구 결과는 다음과 같다. 1. ND 유행지역에서 조사한 26건강면역계군의 예방접종경력은 각양계농장 임의대로의 예방접종 프로그램에 따라서 22계군은 LV와 LV병용. 잔여 4계군은 KV단용에 의해서 각각 면역되었다. 이들의 HI가는 일반적으로 전자가 높았고 후자는 낮은 경향을 보였으며, 그 평균치는 각각 146. 50이었다. 그리고 전자의 22계군 중 특히 낮은 역치(10, 23)를 보였던 그계군은 추후 ND발생을 보았으나 잔여 20계군 및 KV 단용 4계군은 모두 무사히 경과하였다. 2. ND유행지역에서 조사한 ND발생14계군의 예방접종경영은 무접종이 1계군이고 잔여 13계군은 각양계농장 임의대로의 접종프로그램에 따라서 LV단용이 8계군, LV와 KV병용이 5계군이었다. 폐사율에 있어서 후자는 5.1%인데 반하여 전자는 32.5%의 피해 즉 후자에 비하여 6.28배의 월등히 높은 폐사율을 보였다. 한편 ND비발생 4계군은 LV와 KV병용 혹은 KV단용 예방접종프로그램에 의해서 면역되었으며 LV단용계군은 1예도 없었다. 3. 야외에서 조사한 면역계군들의 LV응용은 거의가 ND면역상 불리하다고 보여지는 음수 투여에 의해서 면역되었으며 극히 소수예가 비질내적하 혹은 일정 희척 LV병독액 속에 파면역추의 입, 코, 눈까지 침지하는 특이한 방법으로 면역되었다.

An epizootic of calf diarrhea occurred in an extensive dairy farm located in Gangwondo province in December of 1985. The patients showing fever, chills, complete anorexia and watery diarrhea sometimes dysentery were concentrated among the calves ranged from 8 days to 3 months old and many of them died in acute course. The five carcases were examined by pathological and bacteriological means. The predominant gross lesions were edematous swelling of the mesenteric lymph nodes, profuse catarrhal or diphtheritic enteritis and extensive purulent bronchopnenomonia or lobar fibrinous pneumonia. Microscopically the lesions of the liver and spleen were characterized by coagulative necrotic foci and granulomatous nodules. The spleen and lymph node showed also proliferative changes of reticular cells and involution of intestinal lymphatic nodules were noticed. The strains of Salmonella(S) species isolated from the liver, spleen, bile juice, peritoneal fluid and thoracic fluid were identified serologically as S. dublin. These clinical and pathological findings of the disease were those of acute enteritis form of salmonellosis and characterized by high morbidity and mortality among the calf herd. The report also signifies the first description of an epizootic of bovine salmonellosis caused by S. dublin in Korea.

African swine fever (ASF), caused by the ASF virus, a member of the Asfarviridae family, is one of the most important diseases in the swine industry due to its clinical and economic impacts. Since the first report of ASF a century ago, ample information has become available, but prevention and treatment measures are still inadequate. Two waves of epizootic outbreaks have occurred worldwide. While the first wave of the epizootic outbreak was controlled in most of the infected areas, the second wave is currently active in the European and Asian continents, causing severe economic losses to the pig industry. There are different patterns of spreading in the outbreaks between those in European and Asian countries. Prevention and control of ASF are very difficult due to the lack of available vaccines and effective therapeutic measures. However, recent outbreaks in South Korea have been successfully controlled on swine farms, although feral pigs are periodically being found to be positive for the ASF virus. Therefore, we would like to share our story regarding the preparation and application of control measures. The success in controlling ASF on farms in South Korea is largely due to the awareness and education of swine farmers and practitioners, the early detection of infected animals, the implementation of strict control policies by the government, and widespread sharing of information among stakeholders. Based on the experience gained from the outbreaks in South Korea, this review describes the current understanding of the ASF virus and its pathogenic mechanisms, epidemiology, and control.
