| bulinus nyassanus is an intermediate host for schistosoma haematobium in lake malawi. | at cape maclear on the nankumba peninsula, close to the southern end of lake malawi, schistosoma haematobium is highly prevalent in the local people and many tourists become infected with this parasite each year. a 'bilharzia control programme' was initiated in this area in august 1998, as a development collaboration between the government of malawi, the danish agency for development assistance (danida), and the danish bilharziasis laboratory. although bulinus globosus is a known host for s. hae ... | 2001 | 11454245 |
| density of trematocranus placodon (pisces: cichlidae): a predictor of density of the schistosome intermediate host, bulinus nyassanus (gastropoda: planorbidae), in lake malaŵi. | from the mid-1980s, we recorded a significant increase in urinary schistosomiasis infection rate and transmission among inhabitants of lakeshore communities in the southern part of lake malaŵi, particularly on nankumba peninsula in mangochi district. we suggested that the increase was due to over-fishing, which reduced the density of snail-eating fishes, thereby allowing schistosome intermediate host snails to increase to higher densities. in this article, we collected data to test this hypothes ... | 2012 | 22231863 |
| 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 |
| introgression in lake malaŵi: increasing the threat of human urogenital schistosomiasis? | for the last 15 years, we have studied the relationships among cichlid snail-eating fishes, intermediate snail-host density, and the prevalence of human infection of schistosoma haematobium in lake malaŵi and concluded that the increase of human infection is correlated with the decrease in snail-eating fishes in the shallow waters of the lake. we postulated that a strain of s. haematobium from other parts of africa, which was introduced into the cape maclear region of lake malaŵi by tourists, wa ... | 2014 | 24136387 |
| the schistosome intermediate host, bulinus nyassanus, is a 'preferred' food for the cichlid fish, trematocranus placodon, at cape maclear, lake malawi. | over the last decade, transmission of the schistosome parasites of humans has increased in parts of lake malawi, possibly because over-fishing has led to a decline in the numbers of molluscivorous fish. the stomach contents of 51 wild-caught trematocranus placodon from the cape maclear area of lake malawi have now been investigated and compared with the field abundance of snail species at two sites, close to where the fish were caught. the snails found in the fish stomachs were identified to gen ... | 2006 | 16417717 |
