Characterization of Spirometra erinaceieuropaei plerocercoid
cysteine protease and potential application for serodiagnosis of sparganosis.
We found material assigned to Proteocephalidea in the plerocercoid
stage, presenting a scolex with four simple suckers; both characteristics correspond to the order (Khalil et al.
Sparganosis is an infection caused by the plerocercoid
larvae (spargana) of various diphyllobothroid tapeworms belonging to the genus Spirometra.
After ingestion of the infected fish, the plerocercoids
develop into immature adults and then into mature adult tapeworms, which will reside in the small intestine.
Parasites were in the plerocercoid
stage and inhabited the body cavity.
Of these, the loss of an axoneme in the sperm's tail (male) and the loss of cilia on hexacanths and tails on plerocercoids
(larval) occur more than once.
larvae of Diphyllobothriidae Luhe, 1910: finding in Peruvian sea fish for human consumption.
Accordingly, the route of plerocercoid
infection for humans in Henan Province differs from that in southern China.
To the Editor: Sparganosis is a worldwide parasitic zoonosis caused by infection with spargana, the plerocercoid
larvae of various diphyllobothroid tapeworms belonging to the genus Spirometra (1-3).
To the contrary, an investigation of mature masu salmon captured in the rivers in Hokkaido showed a plerocercoid
infection rate of 20%, although no plerocercoids
were found in masu salmon juveniles that stayed in the rivers for 1.
larvae in the fish muscles are easily missed during food preparation.
latum is transmitted to humans by plerocercoid
larvae present in fish meat and visceral organs (www.
