Pulmonary fluke disease

Pneumococcal disease is mainly caused by the migration of larvae or adults in human tissues and organs, mechanical damage caused by colonization, and immune-pathological reactions caused by metabolites. Infection can be obtained when eating crabs, clams, macrobrachium, aquatic insects, matchworms, etc. that contain pneumocystis live cysts on human or semi-raw food. The first intermediate host of Pneumoparasites is more than 20 types of freshwater snails, and the second intermediate host is crabs, hunting for crustaceans. The final host is a human or mammals such as dogs, cats, and pigs. These animals, other than humans, are also called insect-preserving hosts and are the main source of infection that constitutes the natural epidemic source.
