[Seroepidemiology of toxoplasmosis and ocular evaluation by Amsler grid in patients from the rural area treated at the Jaguapitã county health center, Paraná State, Brazil].
In this study, we collected serum from 82 randomly selected patients from a rural area in Jaguapitã county, Paraná State. All sera were subjected to indirect immunofluorescence assay (IFA) to detect IgG antibodies against T. gondii. Serum titers >/=+ 16 were considered positive. Of the 82 evaluated sera, 68 (82.9%) were positive to toxoplasmosis and 14 (17.1%) were non-reactive. The most common titers found were 64 (23/33.8%) and 256 (16/23.5%), the highest titer being 4096 (8/11.8%). The 82 patients were also evaluated by the Amsler Grid test, with 22 (26.8%) patients presenting at least one alteration in this test. Masculinity was found to be a protection factor in the Amsler grid test (OR = 0.21 0.04 < OR < 0. 86 chi2 = 4,98 p = 0,02). There were no significant statistical differences related to the epidemiological investigation. We concluded that T. gondii has a wide distribution in the population studied.
