Sensory organs are absent from "F. hepatica". Both "F. hepatica" and "F. gigantica" can cause fasciolosis. Climate affects both "F. hepatica" and its intermediate host, the snail. Currently it is usually referred to as either "Capillaria hepatica" or, less often, "Calodium hepaticum". Snails from family Planorbidae act as an intermediate host of "F. hepatica" very occasionally. Proteases secreted by "F. hepatica" have been used experimentally in immunizing antigens. As a person infected by Fasicola hepatica again infected by fasciola gigantica. In Peru, "F. hepatica" in humans occurs throughout the country. Intermediate hosts of "F. hepatica" are freshwater snails from family Lymnaeidae. The genome for "F. hepatica" was published in 2015. Intermediate hosts of "F. hepatica" are air-breathing freshwater snails from the family Lymnaeidae. However, acquired resistance to "F. hepatica" infection is well known in adult cattle. The life cycle of "C. hepatica" may be completed in a single host species. The presence of "F. hepatica" can interfere with the detection of bovine tuberculosis in cattle. In humans "C. hepatica" causes Hepatic capillariasis, a serious liver disorder.
