【 摘 要 】

Changes in the seroprevalence of Dirofilaria immitis infection among shelter dogs between a decade ago and the present were evaluated. Serum samples were collected from 200 adult dogs in urban and suburban areas in Tokyo, Japan, during two 2-year periods (April 1999 to March 2001 and April 2009 to March 2011). Sera were tested for the presence of D. immitis antigen using a specific commercialized kit. The seroprevalence of D. immitis infection was 46% in 1999–2001 and 23% in 2009–2011. A decrease was observed in the prevalence of infection between 1999–2001 and 2009–2011; in particular, the prevalence in urban areas decreased significantly compared with that in suburban areas (P < 0.01). There was no significant difference in prevalence between the sexes in each period, but there was a significant difference between mixed-breed and purebred dogs (P < 0.01). The decrease in prevalence of canine heartworm disease in urban areas could be related to better veterinary care.
