To assess the current status of Dirofilaria immitis infection and to determine whether there were other canine filarial infections in north Taiwan, postmortem examination was conducted in 180 stray dogs more than 12 months old. Blood and serum samples were examined using a modified Knott's test and an antigen-detecting enzyme-linked immunosorbent assay (ELISA) kit, respectively. Filarial infection was found in 60.6% of the dogs: 55% with D. immitis and 12.2% Dipetalonemea reconditum. Moreover, the ELISA was determined to be more sensitive than the Knott's test. Although canine heartworm infection in Taiwan has been attributed to the unrestricted import of dogs from endemic areas, the results of this study indicate that transmission of D. immitis and Dip. reconditum may occur indigenously in the local canine population. This study is also the first record of Dip. reconditum in Taiwan.
