IgG to other parasites including Paragonimus westermani , Paragonimiasis sichuanensis , Schistosoma japonicum , and Spirometra mansoni were all negative.
More recently elevated serum IgG4 levels were reported in two cases of pulmonary Paragonimus westermani infection [9].
It is known that this crab species is recognized as a secondary intermediate host of Paragonimus genus (lung fluke) for mammals, including human beings as the final host.
