Serological survey were conducted on the leptospiral antibody in domestic animals which were fed in the three rural village occurred human leptospirosis. Names of three villages are Shinnam-li, Shinjeop-li and Jinai-li which are located in near the northeastern part of Yeoju town in Kyunggi province. Total 66 serum samples were collected from the domestic animals in which 12 dairy cows, 10 Korean native cattle, 12 pigs and 32 dogs were included. Leptospiral antibody were detected with 4 different serovars of leptospira living antigens, such as Leptospira icterohaemorrhagiae, L. pomona, L. canicola and L. tarassovi by microscopic agglutination test for each serum sample. The results are obtained as follow. 1. All 66 sera collected from the domestic animals at three villages showed negative reaction with 4 different serovars of leptospiral antigen. 2. Only one serum sample taken from a dairy cow in Shinjeop-li showed a weak positive reaction with Leptospira tarassovi. It is suggest that this positive case is not infected with L. tarassovi, but with vaccination. 3. It is indicated that all domestic animals which wen, fed in the villages occured human leptospirosis were not infected with above 4 different serovars of leptospira at least.

Mastitis is characterized by physical, chemical and bacteriological changes in the milk and pathological changes in the glandular tissue of the udder and affects the quality and quantity of milk. The bacterial contamination of milk from the affected cows render it unfit for human consumption and provides a mechanism of spread of diseases like tuberculosis, sore-throat, Q-fever, brucellosis, leptospirosis etc. and has zoonotic importance. Somatic cell count (SCC) is a useful predictor of intramammary infection (IMI) that includes leucocytes (75%) i.e. neutrophils, macrophages, lymphocytes, erythrocytes and epithelial cells (25%). Leucocytes increase in response to bacterial infection, tissue injury and stress. Somatic cells are protective for the animal body and fight infectious organisms. An elevated SCC in milk has a negative influence on the quality of raw milk. Subclinical mastitis is always related to low milk production, changes to milk consistency (density), reduced possibility of adequate milk processing, low protein and high risk for milk hygiene since it may even contain pathogenic organisms. This review collects and collates relevant publications on the subject.

유행성 출혈형 폐염양 환자로부터 분리한 병원체에 대한 환자 항 혈청의 조사와 동물의 감염성 및 이 질환에 의해 사망된 환자의 조직내 균체검사의 결과는 다음과 같다. 1) 분리균에 대한환자의 항 혈청검사에서 42명 중 39명이 항체역가 1 : 40이상의 양성반응으로 나타났다. 2) 균접종에 대한 동물의 감수성 검사에서 guinea-pig은 LD가 $1-2{\times}10^9$ 균수인데 반하여 mouse에서는 LD가$1-2{\times}10^9$ 균수 이상으로 감수성이 낮고, 다람쥐는 거의 저항성으로 나타났다. 감염동물에서는 굵은 5 -10일경 간장, 폐장, 신장, 혈액 및 뇨에서 모두 검출되었다. 감염된 장기의 병리적 소견에서 폐장에는 폐포내 심한 출혈과 단핵백혈구의 침윤 및 기관지 폐염을 나타내고, 간장에는 Kupffer cell외 과다증식, 동양구조내 울혈 및 저산소증 변화, 국소적 허혈성 괴사를 볼 수 있고, 신장의 경우 단 수질내 출혈과 뇨에서는 많은 균과 적혈구를 관찰할 수 있었다. 3)균에 대한 특이 가토 항 혈청은 환자의 항혈청에서와 같이 간접 면역 형광법에 의해 유행성 출혈열 폐염양 질환으로 사망한 환자의 조직내 감염군과 강하게 반응하였다.

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.
