A simple and sensitive duplex polymerase chain reaction (PCR) assay was developed for use in detection of Helicobacter species and H. hepaticus in laboratory mice. Bacteria were extracted and concentrated from fecal pellets and intestinal segments by use of buoyant density centrifugation. To improve quality assurance, an internal control (mimic) for detection of false-negative reactions was included. In addition, cartridges (Capillette) pre-filled with PCR reagents, were used to minimize the hands-on time required, thus reducing the risk of contamination with previously amplified material. Laboratory mice from Swedish animal houses sent to the National Veterinary Institute for health monitoring were found to have high prevalence of H. hepaticus.
