TL;DR: Comparisons of these related species illustrates that whereas HepatoZoon canis appears to be well adapted to its canine host, Hepatozoon americanum, an emerging pathogen producing severe and frequently fatal myositis, is highly virulent and might have recently crossed the species barrier from a wild host.

TL;DR: A new species of Adeleina, Hepatozoon americanum, is described from the skeletal muscle, cardiac muscle, visceral organs, and blood of dogs (Canis familiaris) in the Southern United States.

TL;DR: Results suggest that American Pit Bull Terriers in the southeastern United States may be subclinically infected with B. gibsoni, but subclinical infection was not identified in dogs of other breeds from the same geographic area.

TL;DR: Sequence analysis of 368 bases near the 3′ end of the 18S rRNA gene from each species revealed a pairwise difference of 13.59% in Hepatozoon canis and Hepatozinum.

TL;DR: H canis infection in dogs can be associated with a distinct clinical syndrome that involves chronic myositis, debilitation, and death and appears to be a serious pathogen in the United States that is becoming more widespread geographically.
