Campylobacter fetus infection

Campylobacter fetus infection is an opportunistic, zoonotic bacterial disease caused by the gram-negative bacillus *Campylobacter fetus*

Campylobacter fetus infection is an opportunistic, zoonotic bacterial disease caused by the gram-negative bacillus *Campylobacter fetus* Defining clinical features include sustained bacteremia, infective endocarditis, mycotic aneurysms, septic thrombophlebitis, and, in pregnant patients, adverse outcomes such as chorioamnionitis and spontaneous abortion

Unlike other *Campylobacter* species that primarily produce self-limiting diarrheal illness, *Campylobacter fetus* possesses a protective surface layer protein capsule that resists complement-mediated phagocytosis, conferring a marked propensity for bacteremia and systemic dissemination

The infection predominantly affects immunocompromised individuals, elderly adults, and patients with pre-existing cardiovascular conditions, often presenting with nonspecific fevers or focal, endovascular manifestations
