The schistosome population is over-dispersed (<jats:italic>k<\/jats:italic> = 0\u00b7119) within the murine hosts and ecological factors linked to the patchy environment may be responsible for such aggregated distribution. Analysis of the spatio-temporal variations in prevalences, intensities and abundances showed limited variations of the infection during the 8 years at the level of the whole parasite population but great spatial heterogeneity at the level of local schistosome populations. Inter-populational genetic variability linked to the degree of adaptation of this human parasite to the murine host may explain differences in transmission dynamics between the local populations of <jats:italic>S. mansoni<\/jats:italic>.<\/jats:p>","DOI":"10.1017\/s0031182000061734","type":"journal-article","created":{"date-parts":[[2009,6,5]],"date-time":"2009-06-05T14:25:25Z","timestamp":1244211925000},"page":"291-298","source":"Crossref","is-referenced-by-count":49,"title":["Long-term dynamics of natural populations of <i>Schistosoma mansoni<\/i> among <i>Rattus rattus<\/i> in patchy environment"],"prefix":"10.1017","volume":"104","author":[{"given":"A.","family":"Th\u00e9ron","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J.
