Alignment of Msp1a amino acid repeat sequences of A. marginale detected from Chinese cattle. The 42 repeat types were aligned using the ClustalW method in the MegAlign software. The Msp1a tandem repeats (M, F, τ, Ph9, Is1; 73, 13, 27, MGl10, 154, 103; Me1, 14, 72; 80, C, 3, 17, 10, LJ1, 22–2, 37, 4 and Ph2) identified herein have been reported in previous studies, and 21 new Msp1a tandem repeats were named as Ch1–21. The one letter code was used to reveal the different amino acid sequences of Msp1a repeats. The variable amino acids are highlighted on a black background and gaps indicate deletions/insertions
