title: Seroprevalence of toxoplasmosis in antenatal women with bad obstetric history.
abstract: BACKGROUND
  The occurrence of fetal death is one of the tragedies that confront the physician providing obstetric care. Among the various agents associated with infections of pregnancy, viruses are the most important followed by bacteria and protozoa. Among protozoal infections in pregnancy, toxoplasmosis is reported to have a high incidence, sometimes causing fetal death. The study was intended to observe the seroprevalence of Toxoplasmosis in pregnant women presenting with bad obstetric history (BOH).
  
  
  METHODS
  A total of 92 antenatal women were included in the study (80 in the study group and 12 in control group). The study group comprised of antenatal women with BOH in the age group of 20-35 years. Antenatal women with Rh incompatibility, pregnancy induced hypertension, diabetes mellitus, renal disorders and syphilis were not included in the study. The control group included women in reproductive age group without BOH. All the samples were screened by enzyme linked immuno sorbent assay (ELISA) for Toxoplasma specific Immunoglobulin M (IgM) and Immunoglobulin G (IgG) antibodies.
  
  
  RESULTS
  Of the 80 antenatal women in the study group, 36 (45%) were seropositive for Toxoplasma specific IgG antibodies (P < 0.005), 16 (20%) were seropositive for Toxoplasma specific IgM antibodies (P < 0.005) and 8 (10%) were seropositive for both IgG and IgM antibodies (P < 0.005). Various predisposing factors for acquiring Toxoplasmosis such as contact with cats, contact with soil, food habits, illiteracy, socio-economic status and residential status were also studied.
  
  
  CONCLUSIONS
  We conclude that toxoplasmosis during pregnancy causes congenital fetal infection with possible fetal loss. ELISA was found to be a sensitive serological test for diagnosis of Toxoplasmosis in pregnant women with BOH. Major cause of fetal loss in BOH cases in the study group was abortion.
