OBJECTIVE To evaluate the impact on schistosomiasis of biennial treatment with praziquantel (PZQ) among school-age children in Burkina Faso, the first country that achieved full national coverage with treatment of more than 90% of the school-age population. METHODS A cohort of 1727 schoolchildren (6-14 years old) was monitored at yearly intervals through a longitudinal survey. Additional grou...

Hyalomma anatolicum anatolicum nymphs were collected from two localities in the Sudan: Eddamer in Northern Sudan and Wad-Medani in Central Sudan. They were allowed to moult to adult ticks, which were assessed for Theileria infection in their salivary glands using Feulgen stain. At Eddamer, 49.6% of 123 ticks examined were infected with Theileria and the mean intensity of infection was 1.3 (i.e....

Simultaneous infection with multiple pathogens of the same species occurs with HIV, hepatitis C, Epstein-Barr virus, dengue, tuberculosis, and malaria. However, available methods do not distinguish among or quantify pathogen genotypes in individual patients; they also cannot test for novel insertions and deletions in genetically modified organisms. The strategy reported here accomplishes these ...

We examined the hypothesis that the interaction between concomitant infecting parasites modifies host susceptibility, parasite intensity and the pattern of parasite distribution within the host population. We used a 26 year time series of three common parasites in a natural population of rabbits: two gastrointestinal nematodes (Trichostrongylus retortaeformis and Graphidium strigosum) and the i...

BACKGROUND The implementation of soil-transmitted helminth (STH) treatment programmes occurs in varied environmental, social and economic contexts. Programme impact will be influenced by factors that affect the reduction in the prevalence and intensity of infections following treatment, as well as the subsequent rate of reinfection. To better understand the heterogeneity of programme impact and...

The prevalence of coccidia infection in goats was evaluated in Western Pomerania (Poland) and West Ukraine Province. A total number of 311 goats were examined: 173 from Western Pomerania, including 139 kids (up to 6 month old), and 138 from the Lviv region including 93 juveniles. The study was based on two flotation methods, which helped to establish the number of oocysts in 1g of feces (OPG): ...

Metazoan parasites of the minor stardrum, Stellifer minor (Tschudi) (Osteichthyes, Sciaenidae), caught by artisanal fishery on Chorrillos, Lima, Peru. A research on some community components of parasitefauna of 105 specimens of Stellifer minor (Tschudi, 1844) collected from Chorrillos Fishmarket, Lima, Peru, between May and October 1998 and necropsied to study parasite communities was conducted...

BACKGROUND Schistosomiasis is a debilitating disease, infects millions of people in tropical and subtropical regions. This study assessed the situation of the urinary schistosomiasis among schoolchildren of the Alsaial Alsagair village, Sudan. METHODS A cross-sectional survey was carried out in 2016, in the Alsaial Alsagair village, and 385 samples of urine were collected and processed using ...
