Interpretive Summary: Campylobacter hyointestinalis is composed of two subspecies: subsp. hyointestinalis and subsp. lawsonii. These two subspecies are typically associated with different ruminants: subsp. hyointestinalis is isolated primarily from cattle and subsp. lawsonii is isolated primarily from swine. C. hyointestinalis is also closely related to C. fetus and the C. fetus-like campylobacters. C. hyointestinalis and C. fetus are both commonly isolated from cattle. Although C. fetus is considered to be an important bovine veterinary pathogen, C. hyointestinalis is not associated with clinical disease in cattle; however, C. hyointestinalis occasionally causes gastroenteritis in humans. This report presents the first complete genomes for both C. hyointestinalis subspecies. Although the genetic basis of the apparent host-association in this species is unknown, genetic analysis indicated that the host-association of the hyointestinalis subspecies may be due to dietary differences between the two animal classes (that is, cattle and swine).

Technical Abstract: Campylobacter hyointestinalis is isolated primarily from ruminants and swine, but is also occasionally isolated from humans. C. hyointestinalis is currently divided into two subspecies: subsps. hyointestinalis and lawsonii. This study describes the first closed whole-genome sequences of the subsp. hyointestinalis isolate LMG 9260 and the subsp. lawsonii isolate LMG 15993.
