  • Title: Arcobacter species in diarrhoeal faeces from humans in New Zealand.
    Author: Mandisodza O, Burrows E, Nulsen M.
    Journal: N Z Med J; 2012 Apr 20; 125(1353):40-6. PubMed ID: 22522270.
    Abstract:
    AIM: To determine the prevalence, genetic diversity and antimicrobial susceptibility of Arcobacter spp in faecal samples from humans with diarrhoea in New Zealand. METHODS: An enrichment method was used to isolate Arcobacter spp from diarrhoeal human faeces submitted to a community laboratory in Hawke's Bay. The identity of isolates was confirmed by PCR and their diversity was determined by pulsed field gel electrophoresis (PFGE). Antibiotic susceptibility was established with E test strips. RESULTS: Arcobacter spp were isolated from 12 of 1380 diarrhoeal faecal samples examined (0.9%), including 7 A. butzleri and 5 A. cryaerophilus. Additional enteric pathogens were detected in four of these diarrhoeal faecal samples. All the Arcobacter isolates were genetically distinct and susceptible to ciprofloxacin. Most were also susceptible to erythromycin (92%) but fewer to tetracycline (67%) and ampicillin(50%). CONCLUSION: A. butzleri and A. cryaerophilus cause a small proportion of cases of diarrhoea in humans resident in New Zealand.
