Campylobacter fetus bacteraemia in a healthy individual: clinical and therapeutical implications.
ABSTRACT Campylobacter species are well-recognized common causes of gastrointestinal infections. While Campylobacter jejuni is probably the most common Campylobacter isolated in humans, Campylobacter fetus is rather infrequent and mostly related with bacteraemia. Even on such occasions, it seems that immunocompetent individuals are spared. We report a case of C. fetus bacteraemia in a healthy-except for impaired fasting glucose (IFG) levels-farmer, presenting as an acute febrile syndrome and treated successfully as brucellosis.

ABSTRACT: Bacteria belonging to the species Campylobacter are the most common cause of bacterial diarrhoea in humans. The clinical phenotype associated with Campylobacter infections ranges from asymptomatic conditions to severe colitis and bacteremia. In susceptible patients, Campylobacter infections are associated with significant morbidity and mortality, with both host factors and bacterial factors being involved in the pathogenesis of bacteremia. In the host, age, gender and immune-compromising conditions may predispose for Campylobacter infections, whilst the most important bacterial determinants mentioned in the literature are cytotoxin production and flagellar motility. The role of sialylated lipo-oligosaccharide (LOS) and serum resistance in bacteremia is inconclusive at this time, and the clinical significance of Campylobacter bacteremia is not yet fully understood. More emphasis on the detection of Campylobacter species from blood cultures in susceptible patients at risk for Campylobacter infections will increase our understanding of the pathogenesis and the relevance of Campylobacter bacteremia.European Journal of Microbiology and Immunology. 03/2012; 2(1):76-87.
