Neutrophil activation by Campylobacter concisus.

ABSTRACT:

Background

Campylobacter concisus is an emerging enteric pathogen associated with prolonged diarrhoea and possibly inflammatory bowel disease in children as well as adults, but the interaction with cells of the innate immune system is unclear. The magnitude of systemic immunoglobulin response in acute infection is unknown.

Methods

Neutrophils from healthy volunteers were activated with five faecal isolates of C. concisus from patients with gastroenteritis as well as the oral reference strain C. concisus ATCC33237. Neutrophils were tested for the expression of adherence molecule CD11b by immunoflourescence and for oxidative burst response by chemiluminescence. The opsonic activity in a chemiluminescence assay was assessed with heat treated serum from patients with C. concisus
