Abstract: Background Arcobacter butzleri is a gram-negative rod, with microaerobic growth at an optimal temperature of 37 °C. It was reported to be the fourth most common Campylobacter-like organism isolated from patients with diarrhoea. Objective Characterise a potential outbreak of A. butzleri detected in a short period of time in the University Hospital Marqués de Valdecilla. Methods Eight strains of A. butzleri were detected in our hospital in only two months. Isolates were identified by MALDI-TOF MS system and 16S rDNA sequencing. Enterobacterial repetitive intergenic consensus-PCR (ERIC-PCR) and Pulsed Field Gel Electrophoresis (PFGE) were carried out to assess clonal relationship. Gradient strips (Etest) were used to determine susceptibility by agar diffusion. Results ERIC-PCR and PFGE confirmed the lack of clonal relationship between strains. Erythromycin or ciprofloxacin might be appropriate for antibiotic treatment of infections. Conclusions A. butzleri is an emerging pathogen with increasing incidence, and may be underestimated.
