A 5-year-old male Labrador Retriever that lived outdoors was presented to the animal hospital with a right hind limb lameness. The lameness had been present for more than 10 days, and there was a severe swelling of the right stifle joint. The dog underwent physical, laboratory, and radiographic examinations. As a result, the dog was diagnosed with infectious monoarthropathy secondary to granulocytic ehrlichiosis. The dog received medication for the rickettsial arthritis and surgical treatment for reconstruction of the soft tissue damage caused by the infection. After treatment, the function of the dog's leg was recovered. This report describes a case of atypical monoarthropathy caused by ehrlichiosis in a dog.

국내에서 채집한 진드기의 라임병 및 ehrlichiosis 원인체 보균 상태를 조사하기 위하여 총 516마리 (Ixodes spp. 22마리 , Haemaphysalis spp. 494마리)의 ixodid 진드기를 봄과 가을에 걸쳐 강원도 고산지대 일원에서 채집하였다. 수집한 진드기에서 DNA를 추출·정제한 후 추출한 DNA를 template로 이용하여, Borrelia burgdorferi sensu lato 및 Ehrlichia spp.에 특이하게 반응하도록 제작한 primer를 이용한 중합효소연쇄반응 (polymerase chain reaction, PCR)을 실시하였으며, 이 결과를 oligonucleotide probe를 사용한 southern blotting을 통하여 다시 확인하였다. 총 516마리의 진드기중 B. burgdorferi sensu lato DNA 양성인 진드기는 68 (13.2%)마리 (B. burgdorferi sensu stricto, 2； B. afzelii, 1; B. garinii, 33； B. tanukii, 8； B. turdae, 4)로 나타났으며 이 중 37 (7.2%)마리의 진드기는 southern blot analysis에서도 양성으로 확인되었다. 또한 101 (19.2%)마리의 진드기가 Ehrlichia spp.에 대한 PCR에서 양성이었으나, 이들 중 25 (4.8%)마리만이 southern blot analysis에서 양성으로 확인되었다. 그러나 사람의 병인체로 추정되는 human granulocytic ehrlichiosis (HGE) agent DNA를 보균한 진드기는 확인되지 않았다. 한편 라임병균과 ehrlichiosis원인체를 동시에 보균한 것으로 밝혀진 진드기가 3마리에서 (0.6%) 확인되어, 국내에서도 진드기 교상시 이들 두 가지 열성질환이 동시에 감염될 가능성이 있는 것으로 사료됨으로 진드기 매개성 열성질환에 대한 적절한 진단법 등을 보다 체계적으로 연구하여야 할 것으로 판단된다.

Rodents are well-known reservoirs and vectors of many emerging and re-emerging infectious diseases, but little is known about their role in zoonotic disease transmission in Bhutan. In this study, a cross-sectional investigation of zoonotic disease pathogens in rodents was performed in Chukha district, Bhutan, where a high incidence of scrub typhus and cases of acute undifferentiated febrile illness had been reported in people during the preceding 4-6 months. Twelve rodents were trapped alive using wire-mesh traps. Following euthanasia, liver and kidney tissues were removed and tested using PCR for Orientia tsutsugamushi and other bacterial and rickettsial pathogens causing bartonellosis, borreliosis, human monocytic ehrlichiosis, human granulocytic anaplasmosis, leptospirosis, and rickettsiosis. A phylogenetic analysis was performed on all rodent species captured and pathogens detected. Four out of the 12 rodents (33.3%) tested positive by PCR for zoonotic pathogens. Anaplasma phagocytophilum, Bartonella grahamii, and B. queenslandensis were identified for the first time in Bhutan. Leptospira interrogans was also detected for the first time from rodents in Bhutan. The findings demonstrate the presence of these zoonotic pathogens in rodents in Bhutan, which may pose a risk of disease transmission to humans.
