title: Immunohistochemical detection of Dirofilaria immitis using a rabbit polyclonal anti-serum against adult somatic antigens and excretory-secretory products.
abstract: An immunohistochemical study on tissue sections of kidney, lung, liver and spleen from six dogs naturally infected by Dirofilaria immitis was carried out, using a rabbit polyclonal anti-serum against somatic antigen (SA) of adult worms, excretory-secretory products (ES) of adult worms and fraction C3 of complement (Dog C3). Positive immunoreactions were observed on circulating microfilariae when anti-SA and anti-ES were used, but no differences were noted between the two anti-sera. No antigen deposits were observed when the three anti-sera (anti-SA, anti-ES or anti-C3) were employed as primary antibody. In two cases of human filariosis (by Loa loa and Mansonella streptocerca) no positive immunoreactions were observed.
