Detection of Circulating Immune Complexes in Dog Sera by Immune Adherence Hemagglutination Method

Abstract

Circulating immune complexes (CIC) in the sera from 102 clinically healthy dogs and from 16 Dirofilaria immitis (D.immitis) infected dogs were measured by the immune adherence hemagglutination (IAHA) method. The level of CIC in the sera from healthy dogs was 28.2±29.1 μg/ml. There was no significant difference in the levels of CIC regarding sexes or ages. On the other hand, the level of CIC in the sera from D.immitis infected dogs was 230.3±117.1 μg/ml, which was significantly (p<0.01) higher than that of healthy dogs. The results of this study confirm that IAHA method is one of the reliable means of detecting and/or diagnosing immune complex mediated discases in dogs.
