Toxoplasma gondii infection among pregnant women in Yemen: Factors associated with high seroprevalence.

Introduction: Although toxoplasmosis is an important public health problem, there is scarcity of data on the disease available from Yemen. A cross-sectional survey was conducted in health facilities to determine seroprevalence of Toxoplasma gondii and associated risk factors among pregnant women in Sana'a, the capital city of Yemen.

Methodology: A total of 593 pregnant women were included and examined for anti-T.

A better resolution for integrating methods for monitoring Plasmodium falciparum resistance to antimalarial drugs.

Effective chemotherapy is the mainstay of malaria control. However, resistance of falciparum malaria to antimalarial drugs compromised the efforts to eliminate the disease and led to the resurgence of malaria epidemics. Three main approaches are used to monitor antimalarial drug efficacy and drug resistance; namely, in vivo trials, in vitro/ex vivo assays and molecular markers of drug resistance.

Urinary schistosomiasis among schoolchildren in Yemen: prevalence, risk factors, and the effect of a chemotherapeutic intervention.

Background: Schistosomiasis is one of the most important public health problems in Yemen. The prevalence of urinary schistosomiasis varies considerably across different parts of Yemen and was estimated to be 10% among schoolchildren in Sana'a. Praziquantel (PZQ) is highly effective against all five major human species of schistosomes.

Cases of hydatidosis in patients referred to Governmental hospitals for cyst removal in Sana'a City, Republic of Yemen.

Hydatidosis is a parasitic infestation caused by Echinococcus granulosus. This disease is endemic in many countries including Yemen. The present review article aims to have a glimpse at the present status of hydatidosis in Yemen.

Cryptosporidiosis and other intestinal parasites in 3 Yemeni orphanages: prevalence, risk, and morbidity.

The epidemiological pattern of cryptosporidiosis and other intestinal parasites were studied among 3 orphanages in Sana'a City. A total of 292 orphans (225 males & 67 females), aged 4-20 years old were recruited. A questionnaire of demographic information, health status and other relevant information was filled out for each one.

Intestinal parasitosis among apparently healthy workers at restaurants of Sana'a City, Yemen.

A cross sectional study was conducted on randomly selected 303 apparently healthy workers in 58 restaurants in Sana'a City, with ages between 12 to 70 years 22.12 +/- 8.34).

Anti-leishmanial polyclonal antibodies to assess the performance characteristics of leishmanial antigen detection ELISA.

The polyclonal antibodies raised in rabbits against amastigote antigen extract were purified and fractionated, and IgG class antibodies and from the same antibodies, a peroxidase conjugate (labeled antibodies) reagent were prepared. The antibodies and the labeled antibodies were analyzed for efficacy of the homologous extracted antigens by capture ELISA. The titration curves of the anti-amastigote IgG antibody against extracted antigens showed that both free antibody and corresponding labeled antibody reacted with the original amastigote antigens.

Development of schistosomal school-based health education model for Yemeni schoolchildren.

In this study, 152 students (90 males & 62 females) of primary (5th & 6th grades, 52 males & 30 females) and preparatory (1st & 2nd grades, 38 males & 32 females) schoolchildren of different age and sex group inhabited in two endemic villages with Schistosoma mansoni in Taiz Govenorate were examination. The highest prevalence and intensity of S. mansoni were-among males at the age group from 10 - < 12 years.
