  1. The MSP1a microsatellite sequences were analyzed in 115 A. marginale strains. The microsatellite (sequence in bold) was located between the Shine-Dalgarno (SD; sequence in brackets) and the translation initiation codon (ATG) with the structure: GTAGG (G/A TTT) m (GT) nT ATG. The SD-ATG distance was calculated in nucleotides as (4 × m) + (2 × n) + 1. Abbreviation: NI, not included in the study because the A. marginale strain was not adequately geo-referenced.
