a preliminary study on intermediate snail hosts of schistosomes in river enyau, arua district, uganda. | a total of 1260 snail intermediate hosts of both schistosoma mansoni and schistosoma haemotobium were collected along the non-seasonal river enyau which lies half a kilometre west of arua, a north-western uganda town. the snails collected were biomphalaria pfeifferi 709: biomphalaria choanomphala 457, bulinus bulinus tropicus 94. these were screened for cercariae shedding and 25 b. pfeifferi and 12 b. choanomphalal shed mammalian cercaricae while none of the bulinus (bulinus) tropicus shed any c ... | 1992 | 1505417 |
the intensity of schistosoma mansoni in the fishing villages of bugonga and kitubulu in entebbe peninsula, uganda. | the intensity of schistosoma mansoni infection in the fishing villages of bugonga and kitubulu, and the occurrence of snail intermediate host population in the two villages are described and compared. a total of five hundred and six faecal samples from both villages were examined by modified kato's technique and the prevalence infection rate at kitubulu was 40.3% with mean egg count of 187 eggs per gram(epg) while in bugonga it was 32.4% and 126 epg respectively. the snail intermediate host for ... | 1991 | 1935732 |
schistosomiasis on the entebbe peninsula. | a comparative study of the prevalence of schistosoma mansoni and their intermediate host in the fishing villages of nakiwogo and kigungu is reported. a total of 520 inhabitants from the two villages were examined for schistosoma mansoni. their age varied from 4 to 40 and the infection was found to be higher at nakiwogo 95(36.6%) than at kigungu 40(15.4%). the snails collected were 1,345 biomphalaria choanomphala, 237 biomphalaria pfeifferi, 180 bulinus (bulinus) tropicus, 56 bulinus (physopsis) ... | 1990 | 2112995 |
the biology of biomphalaria choanomphala and b. sudanica in relation to their role in the transmission of schistosoma mansoni in lake victoria at mwanza, tanzania. | a study of the intermediate snail hosts of schistosoma mansoni in lake victoria at mwanza, tanzania, was begun in october 1969, the main aims being to investigate the distribution and seasonal variations in population densities of biomphalaria choanomphala and b. sudanica in relation to the nature of the lake bottom and the biological features of the lake shore, the factors influencing variations in the intensity of s. mansoni transmission along the mwanza shoreline, and the age structure of pop ... | 1972 | 4539821 |
laboratory evaluation of the molluscicidal potency of a butanol extract of phytolacca dodecandra (endod) berries. | the effect of butanol extracts of endod against biomphalaria choanomphala, b. pfeifferi, and bulinus (physopsis) nasutus was tested at different concentrations and for different exposure periods. exposure to 19-25 ppm for 6 hours or to 6-7 ppm for 24 hours caused about 100% mortality. | 1972 | 4539824 |
integrated control trial of schistosomiasis at nakiwogo fishing village near entebbe, uganda. | using the kato katz technique, 600 people living in nakiwogo fishing village at lake victoria, uganda, were examined for schistosoma mansoni infection. the total population of this village was estimated between 1,000 and 1,500 mainly consisting of migrants from western uganda. of the 600 individuals in the study group, 328 people (54.7%) were found to be infected with s. mansoni. the geometric mean egg count was 422 eggs per gramme of stool. a survey of the snail intermediate hosts for s. manson ... | 1996 | 8898461 |
schistosoma mansoni in infants (aged < 3 years) along the ugandan shoreline of lake victoria. | in two complementary epidemiological surveys of villages on the ugandan shoreline of lake victoria, the putative occurrence of intestinal schistosomiasis in the local infants (children aged < 3 years) was investigated. when, during the first survey, 136 mother-and-infant pairs from a total of 12 villages were studied, only 7% of the infants but 45% of the mothers were found to be egg-patent for schistosoma mansoni infection. the use of dipstick tests for urine-circulating cathodic antigen indica ... | 2006 | 16762112 |
the population genetic structure of biomphalaria choanomphala in lake victoria, east africa: implications for schistosomiasis transmission. | the freshwater snail biomphalaria acts as the intermediate host of schistosoma mansoni, a globally important human parasite. understanding the population structure of intermediate host species can elucidate transmission dynamics and assist in developing appropriate control methods. | 2014 | 25406437 |
dna barcoding of schistosome cercariae reveals a novel sub-lineage within schistosoma rodhaini from ngamba island chimpanzee sanctuary, lake victoria. | while schistosoma rodhaini is typically considered a parasite of small mammals and is very scantly distributed in the lake victoria basin, it is known to hybridize with the more widespread schistosoma mansoni, the causative agent of intestinal schistosomiasis. as part of broader parasitological and malacological surveys for s. mansoni across lake victoria, schistosome cercariae were harvested from a field-caught biomphalaria choanomphala taken on ngamba island chimpanzee sanctuary, uganda. upon ... | 2012 | 22448675 |
