Precipitating Antibodies in the Carpet Snake against Parasitic Nematodes

Naturevolume 192pages996997 (1961) | Download Citation



To our knowledge very little attention has been paid to the formation or presence of precipitating antibodies in the cold-blooded vertebrates. Indications of active antibody formation have nevertheless been reported in frogs, turtles and fish; however, these estimations were made using either agglutination or anaphylaxis1. This communication is a survey of naturally occurring antibodies in the carpet snake (Morelia spilotes variegatus) which react positively with the body fluids of their nematode parasites, Amplicaecum robertsi, Ophidascarissp., and Polydelphissp., in interfacial precipitin ring tests.
