<i>ankA</i> gene cluster and host species of the <i>A. phagocytophilum</i> strains, in which <i>ankA</i> could be amplified (n = 386).

1Prevalence of strains in the data set. 2NT = nontypeable. In these samples sequences belonging to two different ankA gene clusters were found. 3n (n) = nontypeable strains (all strains). 4n (n) = strains belonging to the respective ankA gene cluster (typeable strains).
