- Abstract
Abstract Laboratory investigations onGalba truncatulawere carried out to determine if snails coming from four populations known to be natural intermediate hosts ofHaplometra cylindracea, a digenean species of frogs, would not be better hosts for experimental infections withFasciola hepaticathan those originating from two communities in whichH. cylindraceawas never found in the past years. UninfectedG. truncatulawere used to constitute six groups of snails (one per population) before being subjected to individual monomiracidial exposures withF. hepatica. Insignificant differences between mean values were noted for snail survival at day 30 post-exposure, prevalence of snail infection withF. hepatica, and prepatent period. In contrast, the duration of cercarial shedding and the number ofF. hepaticacercariae in the four groups known for natural infections withH. cylindraceawere significantly greater. The use of these last lymnaeid populations for experimental infections withF. hepaticaallows to have high numbers of cercariae because of long patent periods and, as a consequence, strongly reduces the cost price of these larvae for scientific purposes and/or commercial production.
