Studies on the freshwater cercariae of Kerala VII. Echinostomatid cercariae
Proceedings: Animal Sciences, 1981Six species of Echinostomatid cercariae were found in freshwater molluscs of Kerala including three previously described forms, namely, cercariaEchinostoma revolution (Frolich 1802) Looss 1899, cercariaEchinostoma malayanum Leiper 1911 and cercariaEchinostoma ivaniosi Mohandas 1973.

Protease activity in schistosome cercariae
Experimental Parasitology, 1959Abstract It has been shown that the cercariae of Schistosomatium douthitti and Schistosoma mansoni do not possess a true collagenase as determined by incubation of living cercariae and cercarial homogenates with human gingival tissue. These studies confirmed the work of others in showing that these cercariae possess potent proteases as indicated ...

A Trap for the Detection of Schistosome Cercariae
The Journal of Parasitology, 1993A simple trap for schistosome cercariae has been developed using clear nail varnish as a matrix and linoleic acid as stimulant affixed to a 75 x 25-mm glass slide. Schistosoma mansoni cercariae will attach to the surface and easily can be visualized either stained or unstained.

Organization of the Musculature of Schistosome Cercariae
Journal of Parasitology, 2003Phalloidin-fluorescein isothiocyanate staining of filamentous actin was used to identify muscle systems within the cercariae of Schistosoma mansoni. Examination of labeled cercariae by confocal scanning laser microscopy revealed distinct organizational levels of myofiber arrangements within the body wall, anterior cone, acetabulum, and esophagus.

A Cercaria of the Trematode Family Haploporidae
The Journal of Parasitology, 1962Cercaria caribbea LII is described and evidence presented that it is the larva of a haploporid, probably Hapladena varia. The cercaria develops in simple rediae in Zebina browniana and encysts in the open. It is biocellate, the tail is slender and unadorned, and the excretory system is stenostomate with a nonepithelial bladder and primary pores at the ...

The behaviour of the cercaria of Cryptocotyle lingua
Zeitschrift f�r Parasitenkunde, 1974The cercaria of Cryptocotyle lingua responds to the onset of mechanical vibrations and to a decrease in light intensity by an increase in activity. The cercaria shows a decline in activity with age and an increase in activity with increasing temperature. Stimulation by host extract also initiates an increase in activity and penetration behaviour.

A New Cercaria from an Annelid
The Journal of Parasitology, 1961additional specimens of A. gunneri floridus were found in the same location in June and July; one of these was parasitized. Only two species of digenetic trematodes which use annelids as first intermediate host have been reported: Cercaria loossi Stunkard, 1929, from the coelom of the serpulid polychaete Eupomatus dianthus (Verrill) (also known as ...

Schistosoma mansoni: Cercaria to Schistosomule
1974Publisher Summary This chapter discusses the cercaria-schistosomule development of Sclzistosoma mansoni. The characteristic features of embryonic and emerged cercariae and of schistosomules are closely compared and contrasted in respect of tegument, glycocalyx, and tegumentary spines, sensory papillae, nerves and muscle, secretory cells, digestive ...
