Anaplasma bovis–Like Infections in Humans, United States, 2015–2017

Abstract

We detected the DNA of an Anaplasma bovis–like bacterium in blood specimens from 4 patients from the United States with suspected tickborne illnesses. Initial molecular characterization of this novel agent reveals identity to A. bovis–like bacteria detected in Dermacentor variabilis ticks collected from multiple US states.
