Individual worms were identified by electrophoretic analysis of glucose-6-phosphate dehydrogenase, which was characteristic for each isolate. Analysis of the data obtained showed that both heterospecific and homospecific pairs formed between the hybrids and <jats:italic>S. haematobium<\/jats:italic> and <jats:italic>S. intercalatum. S. haematobium<\/jats:italic> and the hybrid are better than <jats:italic>S. intercalatum<\/jats:italic> in forming pairs, and <jats:italic>S. haematobium<\/jats:italic> showed a greater homospecific mate preference compared with the hybrid. Analysis of the data using the Mantel-Haenszel test suggests that mating competition does exist between the schistosomes, with the hybrid being dominant over both the parental species and <jats:italic>S. haematobium<\/jats:italic> being dominant over <jats:italic>S. intercalatum.<\/jats:italic> The hybrid males showed a greater ability than <jats:italic>S. intercalatum<\/jats:italic> and <jats:italic>S. haematobium<\/jats:italic> males in taking away <jats:italic>S. haematobium<\/jats:italic> and <jats:italic>S. intercalatum<\/jats:italic> females from their homospecific males when introduced into a pre-established <jats:italic>S. haematobium<\/jats:italic> or <jats:italic>S. intercalatum<\/jats:italic> infection. They were able to take females from <jats:italic>S. intercalatum<\/jats:italic> homospecific pairs more easily compared with females from <jats:italic>S. haematobium<\/jats:italic> homospecific pairs. The significance of the results is discussed in relation to the epidemiological changes of schistosomiasis in Cameroon, where hybridization between <jats:italic>S. haematobium<\/jats:italic> and <jats:italic>S. intercalatum<\/jats:italic> has taken place, with <jats:italic>S. haematobium<\/jats:italic> and the hybrid managing to replace the endemic <jats:italic>S. intercalatum<\/jats:italic> over the last 30 years.<\/jats:p>","DOI":"10.1017\/s0031182002002883","type":"journal-article","created":{"date-parts":[[2003,5,9]],"date-time":"2003-05-09T09:29:48Z","timestamp":1052472588000},"page":"327-338","source":"Crossref","is-referenced-by-count":23,"title":["Mating interactions of <i>Schistosoma haematobium<\/i> and <i>S. intercalatum<\/i> with their hybrid offspring"],"prefix":"10.1017","volume":"126","author":[{"given":"B.
