| the interaction of schistosoma haematobium and s. guineensis in cameroon. | interactions between schistosomes are complex with some different species being able to mate and hybridize. the epidemiology of schistosomiasis in specific areas of south west cameroon has evolved remarkably over 30 years as a result of hybridization between schistosoma guineensis and s. haematobium. morphological and biological data suggest that s. haematobium replaced s. guineensis in areas of cameroon through introgressive hybridization. data are reported on the use of single stranded conform ... | 2005 | 16153312 |
| isoenzyme analysis of schistosoma haematobium, s. intercalatum and their hybrids and occurrences of natural hybridization in cameroon. | isoelectric focusing of glucose-6-phosphate dehydrogenase (g6pd) produced clearly identifiable profiles for s. haematobium and s. intercalatum and their hybrids. to provide a more detailed analysis of the interactions of s. haematobium and s. intercalatum in south west cameroon over the last 12 years, g6pd analyses were carried out on individual schistosomes collected in kumba in 1990, loum in 1990, 1999 and 2000 and barombi mbo and barombi kotto in 1999. studies were also carried out on the two ... | 2003 | 12895287 |
| water contact and schistosomiasis infection in kumba, south-western cameroon. | kumba, a town with a population of mixed background and socio-economic status, is a new and intense focus of schistosomiasis. although fountains provide clean water, the population still uses the river and streams which cross the town for most of its bathing, laundry and swimming. a multivariate analysis indicated that a local subject's age, ethnic group, knowledge about schistosomiasis and the intensity of his or her contact with the river and/or streams were all significantly associated with s ... | 1994 | 7893177 |
