Fasciola hepatica tiene un ciclo biológico complejo, que incluye un caracol limneido como intermediario, donde acontece su multiplicación larval partenogenética. Se realizó por ello un estudio experimental del ciclo de F. hepatica y se estimó su potencial biótico (r) en Galba truncatula. Habiendo seleccionado 215 de estos caracoles para su infección con miracidios obtenidos a 26°C, en presencia de luz; se procedió a la disección de cinco caracoles cada tres días, realizando el seguimiento de la cuantía de estadíos de F. hepatica mediante microscopía de campo claro, observando características externas y tiempo de desarrollo de miracidios, esporocisto, redias y cercarias. Resultando que el modelo de crecimiento exponencial es el que mejor se ajusta a la dinámica de F. hepatica, con un potencial biótico de 6,69%, una media de 203 cercarias por miracidio y 270 cercarias por caracol.

AbstractExperimental infections of Galba sp. (origin, Colombia) with allopatric isolates of Fasciola hepatica from France or Fascioloides magna from the Czech Republic were carried out during five successive snail generations to determine if this lymnaeid might sustain complete larval development of either parasite. In snails exposed to F. hepatica, 7 of 400 snails harboured several rediae and only two snails contained a small number of free cercariae on day 50 post-exposure. In contrast, the intensity of F. magna infection in Galba sp. progressively increased from the F1 to F5 generations. Spontaneous cercarial shedding of F. magna occurred in 7 of 100 Galba sp. belonging to the F5 generation and the number of shed cercariae did not differ significantly from that noted in control Galba truncatula of French origin. Galba sp. from Colombia can be added to the list of potential intermediate hosts for F. magna.
