title: Sequence analysis of three Ehrlichia ruminantium LambdaGEM-11 clones.
abstract: Three Lambda GEM11 clones were isolated from a large-insert Ehrlichia ruminantium Welgevonden library. The inserts were amplified, sequenced, and analyzed. A total of 39 827 bp was obtained, and 18 different open reading frames (ORFs) were identified. Long repeats (100-200 kbp) were found in all three sequences. These repeats may play a role in the induction of antigenic variation. Along with a 20-kbp sequence of a clone from the E. ruminantium cosmid library, these sequences are the first large sequences to be yielded by the E. ruminantium genome sequencing project.
