Incidence of Toxoplasma and Toxocara antibodies among out-patients in the Ophthalmic Research Institute, Egypt.
Infection by Toxoplasma gondii and Toxocara canis is getting much important nowadays. Both are soil transmitted infections. The present study was planned to detect the incidence of T. gondii and T. canis antibodies among 100 patients attending the outpatient clinics in Research Institutes of Ophthalmology (RIO), whose urine and stool were free from other parasitic stages. Patients were classified into two groups, group I; (70 ocular cases) and group II, (30 non-occular cases). Control group (group III); 30 healthy persons. Sera from all individuals were subjected to IFAT and IHAT to detect Toxoplasma antibodies and IFAT to detect Toxocara antibodies. By using IFAT for Toxoplasma revealed, 25% as a total incidence, 21.4% in group I, 33.3% in group II and 6.6% in group III. While IHAT revealed 51% as a total incidence, 51.4% in group I, 50% in group II and 23.3% in group III. Among group I, retinochoroiditis cases showed the highest incidence and titre. While hydrocephalic cases showed highest incidence and titre in group II. T. canis antibodies revealed 23% as a total incidence, 14.3% in group I, 43.3% in group II and 5% in group III. Cases presented with retinal detachment showed the highest incidence and titre in group I while in group II hepatomegalic cases gave the highest incidence and titre. Concomitant infection of both Toxoplasma and Toxocara was detected in 8% of positive cases.
