Abstract:

Background: Toxoplasma gondii is a ubiquitous, coccidian parasite that causes toxoplasmosis. This infection, if acquired during pregnancy may result in severe damage. It affects a third of the world’s population. In many developing countries, its prevalence is unknown, and data concerning its seroprevalence among pregnant women is scarce in our study area. The objective of this study is to determine the seroprevalence of T. gondii infection and the associated risk factors among pregnant women attending the antenatal clinic (ANC) at the Bamenda Regional Hospital in Cameroon. The results obtained will be useful in giving an estimate of the prevalence among pregnant women thus informing policy on preventive measures.

Methodology: This is a descriptive cross-sectional study of pregnant women recruited between January and April 2018 using systematic random sampling technique. Socio-demographic data of participants and predisposing factors to toxoplasmosis were collected using a pretested structured questionnaire administered to them. Five milliliters of blood were collected and the serum screened for IgG and IgM antibodies against T. gondii using the cassette and buffer immunochromatographic method. The positive IgG cases were tested further by ELISA technique. Data were analyzed using SPSS version 20. Associations between variables were tested by Chi square and p value < 0.05 was considered statistically significant.

Abstract

Toxoplasmosis is caused by an obligatory intracellular protozoon. It causes a wide range of diseases with toxoplasma encephalitis commonly encountered in HIV/AIDS patients. This work was carried out to determine the seroprevalence of toxoplasma antibodies (IgM and IgG) in HIV/AIDS patients attending the Yaoundé University Teaching Hospital (UTH) in Cameroon. Sera were collected from 133 HIV/AIDS patients at the out-patient department and the ELISA technique was employed serologically to determine toxoplasma antibodies. Of the 133 patients 83 (62.4%) were females and 59 (37.6%) were males; ninety three (69.9%) were positive for toxoplasma antibodies. Fourteen (10.8%) of the 93 of seropositive patients presented with both IgG and IgM-antibodies in their sera while fifty six (42.1%) and 8 (6.0%) were only sero-positive for toxoplasma IgG or IgM-antibody respectively This rate of infection was not dependent on the patient’s sex or age (X2=11.49, P>0.05). The data provides enough evidence to conclude that 64.7% of the positive cases were due to reactivated infection.
