关于我省家犬感染钩端螺旋体的情况以往已有报导,并且认为牠是钩体病的重要储存宿主之一。1973年5月粤北阳山县江英公社报告了一次家犬引起的犬热型钩体病流行。近年来,我区已从猪、鼠类、臭鼩鼱和红颊獴等动物分离到致病性钩体。一般认为猪和鼠是我区钩体病的主要宿主动物,而家犬感染钩体情况尚未明。因此,我们于1973年10月8日～11月3日进行了初步调查。 The infection of leptospirosis in domestic dogs in our province has been reported in the past and it is considered as one of the important storage hosts for leptospirosis. May 1973 Yangshan County, Guangdong Province, Jiang Ying commune reported a domestic dog caused by fever-type leptospirosis epidemic. In recent years, my area has been isolated from pigs, mice, stinkbugs and red cheeks and other animals leptospirosis. It is generally believed that pigs and mice are the main host animals of Mycobacterium tuberculosis in our district. Therefore, we conducted a preliminary investigation from October 8 to November 3, 1973.
