  • a Repeat forms A to E were identified by sequencing msp1α in the Florida, South Idaho, Virginia, and Washington-O strains of A. marginale and have been previously reported (1). Forms F to J were identified by sequencing full-length msp1α in the St. Maries strain or the entire repeat region of isolates from persistently infected cattle in the Baker, Oreg., herd. The boldface residues represent substitutions, insertions, or deletions.
