Seroprevalence of Toxoplasma gondii in Females Aged 15–45 Years from Bihor County,Western Romania

Abstract

Toxoplasma gondii is a protozoan parasite that causes an important worldwide zoonosis called toxoplasmosis. This infection is often asymptomatic in immunocompetent people. If the infection occurs in pregnant women, it poses great risks to the infant due to its clinical manifestations as mental retardation, seizures, or chorioretinitis. In this study, we evaluated the seroprevalence of IgG antibodies against T. gondii in females aged 15–45 years in Bihor County, Romania. Serum samples drawn from 1935 females aged 15–45 years were screened for IgG antibodies against T. gondii. T. gondii antibodies were found in 706 females (36.48%) and the proportion of IgG positive females tended to increase with age. The seroprevalence was higher in females residing in rural areas (47.79%) compared with those from urban areas (30.95%). This is the first study on the seroprevalence of toxoplasmosis in females aged 15–45 years from Bihor County, Romania. Our survey brings new and important data regarding the seroepidemiology of T. gondii and provides an insight into the demographic risk factors as a basis for a future prevention program for toxoplasmosis.
