Carbohydrate-mediated Recognition of Larval Mosquito Hosts by Romanomermis culicivorax.
Proteases, glycosidases, and lectins were tested and the results supported a role in host recognition for glycoproteins containing beta-glucose and alpha-mannose on the cuticular surface of host and parasite. Carbohydrates containing alpha-glucose, galactose, fucose, or N-acetylglucosamine residues apparently are not involved in nematode attachment. Chitin or a related N-acetylglucosamine polymer was found in R. culicivorax preparasites. Treatment of preparasites with neuraminidase, which hydrolyzes sialic acids, increased nematode attachment to Anopheles freeborni larvae.
