urinary schistosomiasis in urban and semi-urban communities in south-eastern nigeria.	in view of the massive rural-to-urban migration in nigeria, investigations on transmission of urinary schistosomiasis were carried out in urban and semi-urban communities in nike lake area of enugu state, nigeria.	2013	24454442
schistosomiasis in pre-school-age children and their mothers in chikhwawa district, malawi with notes on characterization of schistosomes and snails.	to complement ongoing schistosomiasis control within national control programmes (ncps) that administer praziquantel to school-age children, assessing the risk and extent of schistosomiasis in pre-school-age children (psac) is important.	2014	24690282
significant population genetic structure of the cameroonian fresh water snail, bulinus globosus, (gastropoda: planorbidae) revealed by nuclear microsatellite loci analysis.	in order to characterize the demographic traits and spatial structure of cameroonians bulinus globosus, intermediate host of schistosoma haematobium, genetic structure of seven different populations, collected from the tropical zone, was studied using six polymorphic microsatellites. intrapopulation genetic diversity ranged from 0.37 to 0.55. interpopulation genetic diversity variation clearly illustrated their significant isolation due to distance with gene flow substantially limited to neighbo ...	2014	24751417
prevalence and transmission dynamics of schistosoma haematobium infection in a rural community of southwestern ebonyi state, nigeria.	a twelve-month epidemio-ecological study on the prevalence, infection intensity, water contact and vector aspects of urinary schistosomiasis was conducted in a rural community of south-west ebonyi state, nigeria, using standard procedures, and involving 894 individuals (527, 58.9% males; and 367, 41.1% females). an overall community prevalence (15.3%) was established with more males (20.7%) than females (7.6%) being significantly positive for both micro-and macro-haematuria (χ² = 0.806; df = 1, ...	2014	24862047
modelling spatial distribution of snails transmitting parasitic worms with importance to human and animal health and analysis of distributional changes in relation to climate.	the environment, the on-going global climate change and the ecology of animal species determine the localisation of habitats and the geographical distribution of the various species in nature. the aim of this study was to explore the effects of such changes on snail species not only of interest to naturalists but also of importance to human and animal health. the spatial distribution of freshwater snail intermediate hosts involved in the transmission of schistosomiasis, fascioliasis and paramphi ...	2014	24893011
schistosomiasis outbreak investigation, empandeni ward, mangwe district, matabeleland south province, june 2012; a case control study.	on 20th of june 2012, 31 pupils from kwite primary school reported to the local clinic complaining of passing bloody urine. a study was conducted to identify factors, the etiology and risks of contracting the disease.	2014	25204324
schistosomiasis in malawi: a systematic review.	schistosomiasis remains an important public health problem that undermines social and economic development in tropical regions of the world, mainly sub-saharan africa. we are not aware of any systematic review of the literature of the epidemiology and transmission of schistosomiasis in malawi since 1985. therefore, we reviewed the current state of knowledge of schistosomiasis epidemiology and transmission in this country and identified knowledge gaps and relevant areas for future research and re ...	2014	25490938
modelling climate change impact on the spatial distribution of fresh water snails hosting trematodes in zimbabwe.	freshwater snails are intermediate hosts for a number of trematodes of which some are of medical and veterinary importance. the trematodes rely on specific species of snails to complete their life cycle; hence the ecology of the snails is a key element in transmission of the parasites. more than 200 million people are infected with schistosomes of which 95% live in sub-saharan africa and many more are living in areas where transmission is on-going. human infection with the fasciola parasite, usu ...	2014	25498001
effects of endosulfan on predator-prey interactions between catfish and schistosoma host snails.	the effect of the pesticide endosulfan on predator-prey interactions between catfish and schistosoma host snails was assessed in static tank experiments. hybrid catfish (clarias gariepinus × c. ngamensis) and bulinus globosus were subjected to various endosulfan concentrations including an untreated control. the 48- and 96-h lc50 values for catfish were 1.0 and <0.5 µg/l, respectively, whereas the 48- and 96-h lc50 values for snails were 1137 and 810 µg/l. to assess sublethal effects on the feed ...	2016	27033099
urinary schistosomiasis among preschool children in malengachanzi, nkhotakota district, malawi: prevalence and risk factors.	this study was designed to determine the prevalence of and risk factors for schistosomiasis among a group of preschool children in malawi. schistosomiasis burden among preschoolers in malawi is not well documented in the literature.	2016	27217911
population genetic structure of the freshwater snail, bulinus globosus, (gastropoda: planorbidae) from selected habitats of kwazulu-natal, south africa.	the freshwater snail bulinus globosus is an important intermediate host of schistosoma haematobium, the causative agent of urinary schistosomiasis. this disease is of major health concern, especially in africa where the majority of cases have been reported. in this study the inter- and intra-genetic diversity and population genetic structure of b. globosus from nine locations in the kwazulu-natal province of south africa was studied using four polymorphic microsatellite loci (bgz1-bgz4). moderat ...	2016	27267152
modelling the spatial and seasonal distribution of suitable habitats of schistosomiasis intermediate host snails using maxent in ndumo area, kwazulu-natal province, south africa.	schistosomiasis is a snail-borne disease endemic in sub-saharan africa transmitted by freshwater snails. the distribution of schistosomiasis coincides with that of the intermediate hosts as determined by climatic and environmental factors. the aim of this paper was to model the spatial and seasonal distribution of suitable habitats for bulinus globosus and biomphalaria pfeifferi snail species (intermediate hosts for schistosoma haematobium and schistosoma mansoni, respectively) in the ndumo area ...	2016	27814746
urogenital schistosomiasis transmission on unguja island, zanzibar: characterisation of persistent hot-spots.	elimination of urogenital schistosomiasis transmission is a priority for the zanzibar ministry of health. preventative chemotherapy together with additional control interventions have successfully alleviated much of the disease burden. however, a persistently high schistosoma haematobium prevalence is found in certain areas. our aim was to characterise and evaluate these persistent "hot-spots" of transmission and reinfection in comparison with low-prevalence areas, to support the intervention pl ...	2016	27986092
divergent effects of schistosoma haematobium exposure on intermediate-host snail species bulinus nasutus and bulinus globosus from coastal kenya.	schistosoma haematobium infection causes urogenital schistosomiasis, a chronic inflammatory disease that is highly prevalent in many parts of sub-saharan africa. bulinid snails are the obligate intermediate hosts in the transmission of this parasite. in the present study, bulinus globosus and bulinus nasutus snails from coastal kenya were raised in the laboratory and exposed to miracidia derived from sympatric s. haematobium specimens to assess the species-specific impact of parasite contact and ...	2017	28115664
