Cercaria of the genus Schistosoma represents a free-swimming developmental stage that to complete its life cycle must contact the mammalian skin. Thereafter, it penetrates the skin and transforms into an intravertebrate stage - the schistosomulum. Therefore, the cercaria represents an infective stage, a link between the intermediate (snail) and the ...

Studies on the Formation and Function of Mucoid Glands in Cercariae: Opisthorchoid Cercariae
The Journal of Parasitology, 1953In the present study four species of opisthorchoid cercariae are included: the cercariae of Euryhelmis monorchis Ameel, 1938 (Heterophyinae), Caecincola parvulus Marshall and Gilbert, 1905 (Cryptogoniminae), and two as yet undescribed species. Euryhelmis monorchis was obtained from Pomatiopsis lapidaria: Caecincola parvulus from Amnicola (Marstonia ...

Ultrastructure of the Schistosoma mansoni cercaria
Micron, 2002The cercaria of the schistosome parasite is a short-lived, free-swimming larval stage that is infective for the mammalian, definitive host. This atlas describes the ultrastructure of the cells that comprise the cercaria of Schistosoma mansoni, a leading causative agent of human schistosomiasis.

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.

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.
