  • 브루셀라증(brucellosis)은 세포내 기생하는 브루셀라균에 의해 발생하는 인수공통감염질환으로써, 결핵과 유사하게 만성육아종성 염증을 일으키고 장기간의 병합 항균요법을 필요로 하는 질환이다. 그럼 음성 단간균(coccobacilli)인 브루셀라균은 bartonella 및 리켓챠 등과 함께 proteobacteria의 2종에 속하며 전통적으로는 주로 침범하는 숙주에 따라 6종으로 분류되는데, 그 중 Brucella melitensis(양, 염소), B. abortus (소), B. suis (돼지) 및 B. canis (개) 등의 4종이 사람 브루셀라증을 일으키는 것으로 알려져 있다.

  • We investigated the prevalence of canine brucellosis in companion and stray dogs between March 2015 and December 2016 and determined the disease characteristics based on the geographic distribution, sex and age of the dogs in South Korea. We conducted a large-scale survey using serological and bacteriological tests. Samples were collected from 2,394 dogs (1,825 companions and 569 strays). Thirty (1.3%) samples were positive for Brucella canis antibodies including 16 (0.9%) from companion dogs and 14 (2.5%) from stray dogs. Two (1.0%) of the 196 samples cultured from the stray dogs were positive. When compared with male dogs, the female companion and stray dogs had a significantly higher prevalence of brucellosis. Moreover, the prevalence of canine brucellosis was significantly higher in stray dogs older than 6 years and the prevalence of the disease in companion dogs was highest in Incheon (2.1%) and Jeolla (2.1%) provinces. Stray dogs from the Daejeon metropolitan area had the highest prevalence of brucellosis (7.9%). National control measures for canine brucellosis have not previously been implemented. Our findings suggest that appropriate screening tests and control measures are necessary to improve the health of dogs and to protect public health in Korea, particularly with the rapid growth of the companion animal industry.

  • Canine brucellosis produce abortions and infertility in dogs and is currently diagnosed by serological methods such as rapid slide agglutination test with 2-mercaptoethanol (2-ME RSAT) and immunochromatographic assay (ICA). Bacterial isolation is considered gold standard for Brucella diagnosis and the polymerase chain reaction (PCR) is an alternative method to bacterial isolation. A total of 36 whole blood samples were collected from dogs reared in area of Chuncheon and were subjected to serology (2-ME RSAT and ICA for B. canis, Rose Bengal test and C-ELISA for B. abortus), blood culture and 3 types of PCRs (BSCP31, 16s rRNA, and OMP-2). All blood samples were negative by serology and blood cultures. The BCSP31 and the OMP-2 PCR detected 5 samples were positive whereas the 16S rRNA PCR detected all samples were negative as serological methods and blood culture did. From the results observed in the present study, we conclude that 16S rRNA PCR could be used for direct PCR for canine blood samples.

  • This study was conducted to investigate the prevalence of canine heartworm infections, canine brucellosis and hematologic values from 153 free roaming dogs in the area of Gwangju city from March to November 2006. Nineteen (12.4%) of 153 samples tested with modified Knott's technique showed positive reaction for microfilariae. Polymerase chain reaction using specific primers for D immitis amplified the expected product from all samples of 19 microfilaremic canine blood samples as determined by the modified Knott's test for microfilariae. The seasonal infection rates of microfilariae were higher in the spring season (10/19, 52.6%) than in the other seasons. The major hematological findings in microfilaremic dogs were mild leukocytosis and mild monocytosis. A total of 100 dogs randomly selected from 153 free roaming dogs were negative for canine brucellosis by serological test using immunochromatographic antibody test kit.
