OBJECTIVES To investigate Toxoplasma infection among pregnant women in relation to exposure to infection risk, age and pregnancy-related risk factors. DESIGN AND METHODS This cross-sectional study involved 294 pregnant women attending ante-natal clinic in Accra who consented to participate. Personal and Toxoplasma infection risk related data were obtained(More)
About 20-90% of the world's population has had contact with Toxoplasma gondii parasites. The aim of this study was to determine the seroprevalence and risk factors associated with T. gondii infection in the Central Region, Ghana. A community-based cross-sectional study was conducted in three selected communities. Serum samples were tested for the presence(More)
A rapid, visually read monoclonal antibody (MoAb)-based dipstick assay for specific diagnosis of urinary schistosomiasis was field tested with microscopy and the use of hematuria and proteinuria in a schistosomiasis hematobia endemic area in Southern Ghana. The study group consisted of 229 individuals (114 males and 115 females) aged 1 to 86 years; 145/229(More)
In 2005, Ghana replaced chloroquine with artemisinin-based combination therapy as the first-line treatment for uncomplicated malaria. The aim of this work was to determine for the first time, polymorphisms in the putative pfATPase6 and pftctp, pfmdr1, pfcrt genes in Ghanaian isolates, particularly at a time when there is no report on artemisinin resistance(More)
School children have been increasingly recognized as health messengers for malaria control. However, little evidence is available. The objective of this study was to determine the impact of school-based malaria education intervention on school children and community adults. This study was conducted in the Dangme-East district of the Greater Accra Region,(More)
A Schistosoma haematobium species-specific mouse immunoglobulin (Ig) G1 monoclonal antibody (mab) Sh2/15.F that bound a 29 kDa peptide was utilized to develop a membrane-based dipstick enzyme-linked immunosorbent assay for specific diagnosis of urinary schistosomiasis. Strips of polyvinylidene difluoride membrane were wetted with methanol and stored in(More)
BACKGROUND Toxoplasma gondii infection can lead to severe disease outcomes in immune-compromised people. This study sought to determine the seroprevalence of anti-T. gondii antibodies among pregnant women, hospitalized children (<5 years old) and HIV-seropositive persons in Accra. METHODS A cross-sectional study was conducted in two hospitals in Accra,(More)
There are three major clonal lineages, types I, II, and III, of Toxoplasma gondii known to cause human toxoplasmosis worldwide. Toxoplasma gondii infections have, however, not been genotyped in Ghana. This study detected the clonal types infecting immune compromised and immune competent individuals in Accra, Ghana. Blood samples were obtained from 148 HIV(More)
OBJECTIVE To investigate the use of artemisinin-based combination and monotherapy by community members and the administrative practices of health professionals in treating malaria in Ghana. METHOD This study is a community-based cross-sectional survey in 11 rural and urban areas in southern Ghana. Using the interviewer method, close-ended questionnaires(More)
Proteins in Schistosoma haematobium infected human urine were concentrated by precipitation with saturated ammonium sulphate 50% (v/v) and various fractions obtained at different stages of precipitation tested for presence of schistosome antigens (ShAgs) by dot-ELISA. The protein fraction (UP2S) obtained following two-times precipitation was found to(More)
