  • Method for detecting animal-infective protozoa in vitro and a method for detecting agents which block the differentiation thereof
    Patent number: 4908308
    Abstract: This invention concerns a method for identifying in vitro an animal-infective form of a parasitic protozoan which comprises recovering total mRNA from the protozoan and detecting in the mRNA so recovered the presence of a mRNA transcript encoding a heat shock protein associated with animal-infective parasitic protozoans, which transcript is present only in the animal-infective form of the protozoan, or quantitatively determining in the mRNA so recovered the number of a mRNA transcript encoding a heat shock protein associated with animal-infective parasitic protozoans, which transcript is present in increased number only in the animal-infective form of the parasitic protozoan.This invention also concerns a method for identifying an agent capable of blocking the formation of the animal-infective form of a parasitic protozoan.
