Answer

In contrast to C jejuni infection, C fetus infection causes diarrheal illness less frequently and is the most commonly identified species in bacteremia. However, C fetus infection that produces diarrheal illness results in clinical manifestations that are similar to those of C jejuni infection. C fetus is an opportunistic agent in debilitated hosts, but healthy hosts may also be affected. [13]

Campylobacter bacteremia is common, and C fetus fetus is frequently isolated from the bloodstream, possibly because it resists the bactericidal activity of serum, while the more common C jejuni does not. Persons who develop Campylobacter bacteremia are usually older and are more likely to have cellulitis, endovascular infection, or a device-related infection. [14]

Systemic illness with a predilection for vascular sites is characteristic. Meningitis, [15] vascular infections, thrombophlebitis, peritonitis and cellulitis can occur. [16]

C fetus infection may cause intermittent diarrhea or nonspecific abdominal pain. It should also be considered in individuals with nonspecific fever who are either immunocompromised or have had exposure to cattle and sheep. [17]
