Concomitant Toxoplasma and Toxocara infections.

Toxoplasmosis being to a large extent a soil transmitted infection is acquired in the same manner and often at the same time as toxocariasis, the source being concomitantly infected cats. 110 sera of patients suspected of toxoplasmosis and found positive by the indirect fluorescent antibody test (IFAT), were also tested for Toxocara antibodies by the IFAT. Seropositivity was found to be 18.1%. On the other hand, 12 sera from patients presenting with toxocariasis and proved serologically positive, were tested to detect Toxoplasma antibodies and only one was positive (8.3%). Association of antibodies of the two parasites was found in 21 sera (17.2%).
