Toxoplasmosis is the disease that caused by Toxoplasmagondii which can infected all worm bloodanimals and it is most famous parasite in human. The study aims is to show the seroprevalenace of toxoplasmosis among abortive women in Thi-Qar province. Its include 470 blood samples collected from abortive women in emergency unit of Bent ?Al Huda and Al-Hubboby Hospitals and 30 women as a control(women with normal pregnancy and birth without infected with toxoplasmosis). Samples were collected from October 2017 till October 2018 with age (15-40) years. These sampleswere first tested with latex agglutination test (LAT) to detect the positive sample, which give agglutinate, then with Enzyme Linked Immunesorbent Assay (ELISA) to detect IgG,IgM antibodies of Toxoplasma.It was found from the present studythatthe (ELISA) test is more specific for Toxoplasma diagnosis than (LAT).The seroprevalencefor IgG antibody was 36.45%, IgM 4.52%and for both 1.94%.the high seroprvalent of toxoplasmosis was found in urban (26.5%) than rural (16.5%).In age group (20-24) years the seroprevalentwas 12.58% found and the high ratio(47.14%) was recorded in the aborted women with first trimester more than second trimester(30.65%). The purpose of the present study is to evaluate the seroprevalence of T. gondiiantibodies (IgG, IgM) in aborted women and the association between this parasite and Cytomegalovirus and Rubella.Risk factors (age, sex, time and number of abortion) on infection also investigated.
