Sera from patients with ocular and visceral manifestations of toxocariasis were tested by precipitin absorption (PAT), counter-immunoelectrophoresis (CIEP), indirect fluorescent antibody (IFAT) and ELISA. The ocular cases revealed a percentage of positivity of 36% by PAT, 0% by CIEP, 32% and 28% by IFAT with embryonated egg (EE) and frozen section antigens (FS) respectively and 40% by ELISA. The visceral cases revealed 44% positively by PAT, 24% by CIEP 52% and 48% by IFAT with EE and FS respectively and 52% by ELISA. Statistical evaluation was done to interpret the results.
