  • 3세의 암컷 닥스훈트견이 뒷다리의 부전마비와 사지냉감을 주증으로 본원에 내원하였고 진단을 위해 병력청취, 신체검사, 신경계 검사 및 혈액검사를 실시하였다. 복부 및 심장 초음파 검사 결과, 심장사상충의 성충으로 의심되는 소견이 정상 기생부위 이외의 장소에서 관찰되었다. 효소면역측정법을 이용한 심장사상충 항원 키트 검사 결과 양성반응이 확인되었다. 환자는 입원 당일 혼수상태에 빠져 보호자의 요청으로 안락사 되었다. 보호자의 동의 하에서 실시된 사후 부검 결과 심장의 4방과 대동맥, 복대동맥 및 엉덩동맥에서 높은 충체 부하의 심장사상충 성충이 확인되었으며, 이로 인한 다량의 전신성 혈전색전증 또한 관찰되었다. 본 증례에서는 전신 순환계로의 개 심장사상충 이소기생의 임상적 특징과 진단 영상 및 사후 부검 결과를 소개하였다.

  • The studies on the liver fluke of Korea have been reviewed. The fluke is Fasciola hepatica. Its intermediate host is Lymnaea biridis, whose principal habitats are rice paddies. The first fascioliasis of Korean native(beef) cattle was reported in 1915. Bovine fascioliasis is present throughout the conuntry, including north Korea, with the average prevalence of 30%. The prevalence of the disease is about the same in dairy cattle, which have been imported from other countries since 1960s. The disease was also found in Korea in other species of animals such as sheep, goats, deer of zoo and farms, and guinea pigs of a laboratory. Human fascioliasis was reported ; 35 cases by fecal examination and 11 by both parasitology and pathology. Of the latter 11 cases, 5 were ectopic parasitism. Economic loss due to the reduced carcass weight and milk production, and liver condemnation was great. Almost all flukicides developed in other countries are commercially available in Korea.

  • A 36-year old Korean woman consulted a clinic for a regular gynecological examination, and a mass was noticed in her pelvis. She was referred to the Asan Medical Center, Seoul where transvaginal ultrasonography confirmed a pelvic mass exceeding 10cm in diameter. She received total abdominal hysterectomy and bilateral salpingoophorectomy, and a borderline serous neoplasm with micropapillary features involving the left ovary and right ovarian serosa was histopathologically confirmed. In addition, a section of a nematode with numerous eggs was found in the parenchyma of the left ovary. The worm had degenerated but the eggs were well-preserved and were identified as those of Enterobius vermicularis. She is an incidentally recognized case of ovarian enterobiasis.

  • Background: Since 2013, the number of requests for diagnosis for horses based on neurological symptoms has increased rapidly in South Korea. The affected horses have commonly exhibited symptoms of acute seasonal hindlimb ataxia. A previous study from 2015-2016 identified Setaria digitata as the causative agent. Objectives: This study is an epidemiological investigation to find out risk factors related to the rapid increase in hindlimb ataxia of horses due to aberrant parasites in South Korea. Methods: An epidemiological investigation was conducted on 155 cohabiting horses in 41 horse ranches where the disease occurred. The surrounding environment was investigated at the disease-causing horse ranches (n = 41) and 20, randomly selected, non-infected ranches. Results: Hindlimb ataxia was confirmed in nine cohabiting horses; this was presumed to be caused by ectopic parasitism. Environments that mosquitoes inhabit, such as paddy fields within 2 km and less than 0.5 km from a river, had the greatest association with disease occurrence. Conclusions: Most horse ranches in South Korea are situated in favorable environments for mosquitoes. Moreover, the number of mosquitoes in the country has increased since 2013 due to climate change. Additional research is required; however, these data show that it is necessary to establish guidelines for the use of anthelmintic agents based on local factors in South Korea and disinfection of the environment to prevent disease outbreaks.
