N2 - The aim of the present study was to identify the species that are natural intermediate hosts of Fasciola hepatica in a Research Centre in Chapa de Mota, State of Mexico, Mexico, where temperate and humid conditions prevail. Also, the magnitude and dynamics of the natural infection in four biotopes were analysed. The study was performed between October 2000 and November 2001. The molluscs were collected, identified and studied for trematode infection. Soil humidity and temperature were determined monthly. A total of 4042 snails were collected 3372 (83%) were Fossaria humilis and 670 (17%) F. bulimoides. F. hepatica was present in 2537 (75.2%) and 515 (76.9%) of the two snail species, respectively. Temperature, soil humidity and microenvironment affected the dynamics of the host population and the parasite infestation, with a significant increase from August to November 2001. The highest prevalence was observed in the warmer and more humid biotopes.
