متن کاملThe life history of Echinostoma paraensei sp. n. (Trematoda: Echinostomatidae).
The life history of Echinostoma paraensei, a new Brazilian species with 37 collar spines, has been completed experimentally. The planorbid snail Biomphalaria glabrata serves as first intermediate host, and intramolluscan stages also develop in Physa rivalis. Sporocysts usually develop in the heart. Rediae are of two types, distinguishable by large or small pharynges. Cercariae released 25 or mo...
متن کاملGerminal elements and their development in Echinostoma caproni and Echinostoma paraensei (Trematoda) miracidia.
Among the large cells located in the posterior of Echinostoma caproni and E. paraensei miracidia are secretory cells, germinal cells (GC), and undifferentiated cells. Secretory cells do not give rise to progeny, whereas GC do. Undifferentiated cells develop into GC that can also divide to produce embryos. Cleavage of GC of E. caproni occurs only after the parasite has entered the snail host and...
متن کاملEffects of glucose on survival, infectivity and linear movement of the cercariae of Echinostoma caproni.
The effects of glucose in artificial spring water (ASW) on the survival, infectivity, and linear movement of Echinostoma caproni cercariae were studied. Cercariae maintained at 23 degrees C in 1% glucose in ASW (ASWG) or ASW alone, reached 50% survival at 26 and 23 h, respectively. All cercariae in ASWG and ASW were dead by 50 and 32 h, respectively. Infectivity to juvenile Helisoma trivolvis (...
متن کاملStudies on the brackish water cercariae in Japan. III. Three new echinostome cercariae in Tokyo Bay, with a list of Japanese echinostome cercariae (Trematoda).
The present paper reports three new echinostome cercariae with a review of known 18 spp. of Japanese echinostome cercariae. They were found from the brackish water snails collected from a muddy seashore at Urayasu during the past years from 1944 to 1952. One of these, Cercaria pseudo grani f era n. sp., bearing a strong resemblance to Cercaria grani f era Ogata, 1943, differed from it in detail...
