The genome of anaplasma: DNA base composition and DNA/DNA hybridization

The Tm value of DNA from Anaplasma centrale and Anaplasma marginale was found to be 87.1 degrees C and 89.3 degrees C, respectively. The G + C content, calculated from the Tm, was 45.1% for A. centrale and 48.5% for A. marginale. Identical hybridization patterns were obtained when the DNA from one species was hybridized to restriction endonuclease-digested DNA from the other species.
