Comparison of ELISA reactivity of canine sera against PQ10.

<p>ELISA was performed in different groups of dogs (N: negative group; P: positive group). Subgroup N1: samples with negative results in EIE-LVC kit and RIFI, from animals born in kennels with wire mesh in a non-endemic area (Ouro Preto, Minas Gerais state, Brazil). From an endemic area (Belo Horizonte, Minas Gerais state, Brazil), subgroup N2 shows samples with negative results in EIE-LVC kit, RIFI and PCR; subgroup N3 shows samples with negative results in EIE-LVC kit and RIFI. Subgroup P1: samples with positive results in EIE-LVC kit, RIFI and DPP, from endemic area animals (Teresina, Piauí state, Brazil). From other endemic area (Belo Horizonte, Minas Gerais state, Brazil), subgroup P2 shows samples with positive results in EIE-LVC kit, RIFI and PCR; subgroup P3 shows samples with positive results in EIE-LVC kit and RIFI.
