A histochemical study of the cephalic-cervical system of a gnathostomatid nematode, Echinocephalus sinensis, parasite of oysters and rays


, : A histochemical study of the cephalic-cervical system of a gnathostomatid nematode, Echinocephalus sinensis, parasite of oysters and rays. Zeitschrift Fuer Parasitenkunde: 631: 59-63

Glycogen, protein, succinic dehydrogenase, adenosine triphosphatase, elastin and collagen were demonstrated within the cephalic-cervical system of adult and 3rd-stage Echinocephalus sinensis. Weak positive histochemical reactions were observed for the presence of sulphated mucosubstances, esterase, acetylcholinesterase, lipids and acid phosphatase. Negative results were obtained for leucine aminopeptidase, alkaline phosphatase, phosphorylase, neurosecretory substances and proteases.
