Sentences with phrase «latex agglutination»

Diagnosis of canine dirofilariosis in animals which originate from a low - endemic region is difficult for 3 main reasons: 1) possible absence of circulating microfilariae (occult disease), 2) high frequency of a low number of adults, which in turn produces false negative results, using either ELISA or latex agglutination test, 3) possible false sero - positive results, due to cross-reaction with adult antigens of Dirofilaria (Nochtiella) repens (Schrey, 1996), the agent of subcutaneous dirofilariasis causing chronic pruritic dermatitis in dogs (Tarello, 1999).

Consequently, occult disease can be diagnosed by tests using monoclonal antibodies to circulating adult antigens (ELISA or latex agglutination).
