Following field observations, the ability ofFasciola hepatica to develop in domestic rabbits as compared with sheep was investigated under experimental conditions. The results indicate that development ofF. hepatica is impaired in various phases after rabbit passage. Only 4.2 percent of the metacercariae gained after one rabbit passage developed to adultF. hepatica in sheep, whereas the respective percentage after sheep passage was 51.2 percent. It can be calculated that after rabbit passage 4.5 liver flukes develop from 100F. hepatica eggs as compared with 2,141.3 parasites after sheep passage. |
