T1 - Diversity of Anaplasma phagocytophilum Strains, USA T2 - Emerging Infectious Disease journal PY - 2009 VL - 15 IS - 6 SP - 928 SN - 1080-6059 AB - We analyzed the structure of the expression site encoding the immunoprotective protein MSP2/P44 from multiple Anaplasma phagocytophilum strains in the United States. The sequence of p44ESup1 had diverged in Ap-variant 1 strains infecting ruminants. In contrast, no differences were detected between A. phagocytophilum strains infecting humans and domestic dogs.
