title: Immunological analysis of agglutination in Dirofilaria immitis microfllariae.
abstract: The mechanism of agglutination phenomenon of Dirofilaria immitis microfilariae was analyzed. Circulating microfilariae were collected from a D. immitis-infected microfilaremic dog and cultured in the several kinds of sera from dogs and animals. The agglutination of D. immitis microfilariae is a specific phenomenon due to some immune complexes formed with the anti-microfilarial antibody, heat-instable factor(s) and excretory-secretory products of microfilariae. Only live microfilariae were agglutinated and the agglutinated microfilariae remained alive as long as 27 days in culture in vitro.
