ABSTRACT
Toxoplasmosis is considered as an important risk factor for bad obstetric history (BOH) and one of the major causes of congenitally acquired infections. The present study aimed to estimate the seropositivity of T. gondii infection and associated risk factors among the attendees of high risk pregnancy and low risk antenatal care clinic of Minia Maternity and Pediatric University Hospital, Minia, Egypt. The study was carried out from April 2013 to April 2014 through 2 phases, the first phase was case-control study, and the second phase was follow-up with intervention. A total of 120 high risk pregnant and 120 normal pregnant females were submitted to clinical examinations, serological screening for anti-Toxoplasma IgM and IgG antibodies by ELISA, and an interview questionnaire. Seropositive cases were subjected to spiramycin course treatment. The results showed that the seroprevalence of toxoplasmosis in high-risk pregnancy group was 50.8%, which was significantly different from that of normal pregnancy group (P<0.05). Analysis of seropositive women in relation to BOH showed that abortion was the commonest form of the pregnancy wastage (56.5%). The high prevalence of T. gondii seropositive cases was observed in the age group of 21-30 years. Post-delivery adverse outcome was observed in 80.3% of high-risk pregnancy group compared to 20% of normal pregnancy group. There was a statistically significant relationship between seropositivity and living in rural area, low socioeconomic level, and undercooked meat consumption (P<0.05). Serological screening for anti-Toxoplasma antibodies should be routine tests especially among high-risk pregnant women.

Schistosomiasis is a major health problem in our country. This work is carried out for detection of specific circulating immune complexes [CICs] in S. haematobium infected children as a trial to evaluate their potential use in immunodiagnosis of the disease and in assessment of disease intensity and morbidity. Sixty seven Egyptian children from El-Minia and Sharkia Governorates were included in this study, 50 of them were infected with S. haematobium [active cases], 5 infected with parasites other than Schistosoma [infected control] and 12 children were parasites free [normal control]. Sera of all cases were examined to detect specific schistosomal circulating immune complexes. Indirect ELISA assay using monoclonal antibody 128C3/3/21 as a coating antibody was used. Forty seven out of fifty actively infected cases had positive circulating immune complexes level yielding a test sensitivity of 94 percent. All of the normal control group had negative CIC level yielding a test specificity of 100 percent. The level of CICs was significantly higher in heavily infected children [those excreting >50 eggs/l0ml urine] when compared with those with light infection [excreting <50 eggs/l0ml urine]. ELISA using highly purified monoclonal antibody appeared to be a specific and sensitive test for detection of schistosomal CICs level in the serum and evaluating the intensity of infection
