Biochemical Investigations of the Host-Parasite Relationship of Mosquitos and the Parasite Fungus 'Lagenidium sp.'.

Abstract

A comparative investigation of the nature of the trehalase of Culex quinquefasciatus pipiens and the trehalase of its fungal parasite Lagenidium giganteum shows some very important control differences. The mosquito enzyme is under regulatory control; in contrast, the mycotic enzyme is not, and is a more rugged enzyme seemingly constructed for more advantageous utilization of trehalose. The implications in parasitology and biological control are discussed. Further work has been done on the analysis of the amino acids and sugars in Culex as well as Aedes - both normal and infected populations. The fungus has been shown to produce a strong extra-cellular protease whose partial characterization shows that it is an alkaline enzyme, serine catalyzed, approximately 10,000 daltons molecular weight and is probably involved in infection by the zoospore.
