Abstract

A total number of 100 fecal samples were examined for the presence of Giardia intestinalis infection in dogs using a Giardia ELISA kit (SNAP$^{(R)}$ test, IDEXX Laboratories, Inc., Westbrook, ME). 49 males and 51 females were examined for a G. intestinalis infection in Daejeon and Chungnam area of South Korea. The overall positive rate of G. intestinalis infection was 12.00%. G. intestinalis infection resulted to be more prevalent in males (12.24%) than in females (11.76%), and in symptomatic dogs (18.18%) than in asymptomatic dogs (11.54%). There were no significant differences between the two groups. 19.60% being found in the < 2-year-old group, 4.08% in the over 2 year-old group. $X^2$ analysis revealed a significantly higher prevalence (p < 0.05) in the < 2-year-old group than in the other, and a significantly higher prevalence in dogs kept in a shared kennel (36.00%, p < 0.001). This study is the first survey of G. intestinalis infection prevalence in South Korea according to life style (particularly between dogs kept in a shared kennel and that of dogs kept separately) using an ELISA kit, and this study is expected to provide a useful reference for clinicians and breeders.

본 연구는 한국의 대전과 충남 지역에 있는 개 100마리에서 실내견 (25마리)과 실외견 (75마리)을 구분하여 지알디아증의 유병률을 조사하였다. 모든 샘플은 Giardia SNAP 키트($SNAP^{(R)}$ test, IDEXX Laboratories, Inc., Westbrook, ME)를 이용하여 감염여부를 조사하였다. 지알디아증은 실외견(11/75, 14.66%)이 실내견(1/25, 4.00%) 보다 유의성 있는 높은 유병률은 나타내었다. 또한 자견(< 2yr: 10/51, 19.60%)이 성견(> 2yr: 2/49, 4.08%) 보다 유의성 있는 높은 유병률은 나타내었다. 임상증상을 나타내는 개는 증상이 없는 개보다 높은 유병률을 나타내었으나 (증상: 4/22, 18.18%, 무증상: 9/78, 11.54%) 통계학적으로 유의하지는 않았다. 실외견 중 분리되어 단독으로 기르는 개(2/50, 4.00%)보다 합사하여 여러 마리가 같이 생활하는 개(9/25, 36.00%)에서 높은 유병률을 나타내었다. 세계 여러 나라의 다양한 지역에서 지알디아증 유병률에 대한 조사는 많이 진행되었으나, 사육 패턴에 따른 유병률을 평가한 적은 없기에 본 연구의 의의가 있다.
