Characterisation of the loci encoding the glutamic acid and alanine rich protein of Trypanosoma congolense.

abstract：:Malaria transmission occurs during a blood-meal of an infected Anopheles mosquito. Visualization and quantification of sporozoites along the journey from the mosquito midgut, where they develop, to the vertebrate liver, their final target organ, is important for understanding many aspects of sporozoite biology. Here w...
