During the infection the parasite comes across an array of environments such as different host tissues or the immune response. [20] Studies have shown that O. unilateralis reacts heterogeneously by secreting different metabolites according to the host tissue it encounters and whether they are live or dead. [ 19 ]
Paragonimiasis is a parasitic infection caused by the lung fluke genus, Paragonimus. It primarily affects humans (and other mammals) that consume raw or undercooked freshwater crabs, crayfish or snails infected with the parasite. [22] The transmission of paragonimiasis occurs through the ingestion of metacercariae, the infective form of the ...
Although snails infected by other Leucochloridium species are reported to continue to reproduce, [3] snails infected by L. paradoxum often show a reduction of the sexual organs. [ 6 ] The appearance and behaviour of the sporocysts is a case of aggressive mimicry , where the parasite vaguely resembles the food of the host, thereby gaining the ...

These can be categorized into three groups; cestodes, nematodes and trematodes.Examples include: Acanthocephala; Ascariasis (roundworms); Cestoda (tapeworms) including: Taenia saginata (human beef tapeworm), Taenia solium (human pork tapeworm), Diphyllobothrium latum (fish tapeworm) and Echinococcosis (hydatid tapeworm)
Humans can become infected with Echinostoma by eating infected raw or undercooked food, particularly fish, clams and snails. [3] Infection with these parasites tends to be common in regions where cultural dishes require the use of raw or undercooked food that may be infected with Echinostoma. [19] A mild infection may not have any symptoms. [20]
Giant African land snails, an invasive species of mollusk, poses a threat to Florida residents as it can spread meningitis from a parasite it carries.
Trematodiases can be transmitted through food or water that contains larval forms of the parasite. [1] [5] Infections can be transmitted through aquatic organisms which act as a host for the maturity of the parasite. [5] Foodborne trematodiasis is transmitted when organisms ingest contaminated undercooked food including aquatic plants and ...
