摘要

Asimpleandsensitiveduplexpolymerasechainreaction(PCR)assaywasdevelopedforuseindetectionofHelicobacterspeciesandH.hepaticusinlaboratorymice.Bacteriawereextractedandconcentratedfromfecalpelletsandintestinalsegmentsbyuseofbuoyantdensitycentrifugation.Toimprovequalityassurance,aninternalcontrol(mimic)fordetectionoffalse-negativereactionswasincluded.Inaddition,cartridges(Capillette)pre-filledwithPCRreagents,wereusedtominimizethehands-ontimerequired,thusreducingtheriskofcontaminationwithpreviouslyamplifiedmaterial.LaboratorymicefromSwedishanimalhousessenttotheNationalVeterinaryInstituteforhealthmonitoringwerefoundtohavehighprevalenceofH.hepaticus.
