Characterization of the filarial genome

Abstract

Filarial parasites are just beginning to be studied at the genetic level. The potential of recombinant DNA technology for identifying parasite genes that are important in the pathogenesis of filarial disease or for the survival of the parasite is enormous. Work in several laboratories has already identified genes which encode ribosomal RNAs, as well as highly repeated DNA sequences that can be used as diagnostic probes. In addition, new methods to separate chromosomes will allow the physical mapping of parasite genes without the requirement for classical genetic analysis, which would be difficult in filariids.
