Toxoplasmosis is the commonest cause of infectious posterior uveitis in humans and can lead to blindness and low vision in both immune-competent and immunecompromised persons worldwide. The aim of this study was to determine the prevalence of Ocular Toxoplasmosis (OT) and potential risk factors among livestock farmers and raw meat handlers in Uyo.
This was a descriptive cross-sectional community-based study involving clinical eye examination, laboratory detection of anti-Toxoplasma gondii IgG antibody and HIV testing. Participants’ other information was obtained using interviewer-administered questionnaire.
There were 339 participants aged 15-78 (mean 34.8±11.6) years,283 (83.5%) were males 56(16.5%) were females; 189 (55.8%) tested seropositive for anti-Toxo. gondiiIgG antibodies. Eight (2.4%) had presumed ocular toxoplasmosis (POT); 6 of the 8 were seropositive for anti-T.gondiiIgG antibody; and 2 of the 8 POT (25%) were HIV-seropositive. Of the 189 who were anti-T.gondiiIgG antibody seropositive, 6 (3.2%) had OT. Factors associated with OT were age (31-50 years) and female gender (P = 0.049 and 0.001, respectively). HIV infection was associated with POT (P=0.033). Most of the ocular lesions (87.5%) were unilateral and located at the posterior pole (77.7%).
The prevalence of presumed ocular toxoplasmosis (POT) and ocular toxoplasmosis (OT) among livestock farmers and raw meat handlers in Uyo are 2.4% and 1.8%, respectively. Potential risk factors are being female, and persons between fourth and fifth decades of life. Awareness creation on toxoplasmosis among this occupational group is advocated.
