| immunohistochemical detection of dirofilaria immitis using a rabbit polyclonal anti-serum against adult somatic antigens and excretory-secretory products. | 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 de ... | 1997 | 9802110 |
