SEROPREVALENCE AND INCIDENCE RATES OF TOXOPLASMA GONDII INFECTION AMONG PREGNANT WOMEN IN AN IRAQI DIST

Abstract

The aim of this study is to investigate the seroprevalence and the incidence rates of Toxoplasma gondii infection, as well as to follow-up the events of seroconversion during the gestation period in a group of pregnant women (irrespective of their ages) living in the Wasit governorate /Iraq during the period from January 2004 to March 2005 .The seroprevalence rate of T.gondii infection was screened which ranged from 22.42% to 27.75% (mean 25.05%) for the three samples that were taken along the three trimesters of pregnancy from 272, 252 and 245 pregnant women in the first, second and third trimesters respectively.The incidence rate for T.gondii infection was 4.76% for the period between the first and second trimesters of pregnancy, whereas it was 7.12% for the period between the second and third trimester of pregnancy. Different patterns of seroconversion had occurred during the gestation period which was used to estimate the approximate time of infection whether it was during or before pregnancy which is of a vital importance as a risk factor for the rate of transmission of infection from mothers to fetuses
