Intra-abdominal infection with Campylobacter curvus: case report and review of the literature release_vzc33eogqrgahgfnrls7erwdmy

Abstract

Campylobacter curvus is a Gram-negative bacteria associated with periodontal disease in humans. Cases of extra-oral manifestations of infection are rare with only six reported cases of extra-oral infection including this report that have been identified in the current literature. Molecular methods are generally used to identify C. curvus while optimal antibiotic choice and duration to treat extra-oral infections for this pathogen is unknown. A 63-year-old male with a background history of alcoholic pancreatitis presented with fever and malaise who was found to have radiological intra-abdominal collections. Drainage of these collections identified C. curvus via matrix-assisted laser desorption/ionisation time of flight (MALDI-TOF) mass spectrometry with high probability and identification further confirmed by whole-genome sequencing. Antibiotic susceptibility testing to erythromycin and ciprofloxacin of C. curvus was performed using E-test diffusion methods along with investigation for the presence of resistance genes. The patient was treated with intravenous piperacillin-tazobactam followed by ciprofloxacin for 4 weeks total with good clinical recovery. Extra-oral manifestations with the pathogen C. curvus are rare with few cases described in the literature. There is minimal data on susceptibility patterns, optimal antibiotic treatment and duration. Treatment of extraintestinal C. curvus infections in humans should encompass both adequate source control and antibiotic therapy.
