ABSTRACT
Objective To establish a rapid, simple, sensitive, and specific multiplex real-time PCR method for quantitative detection of Campylobacter jejuni, Salmonella and Shigella in tree shrews.Methods Specific primers and probes were designed, according to the HipO gene of Campylobacter jejuni, inV gene of Salmonella and ipaH gene of Shigella.The primers were confirmed by single pathogen quantitative PCR, and the sensitivity and specificity of the multiplex PCR were analyzed.Finall, the samples of experimental tree shrews were detected by this multiplex PCR method.Results The PCR element of TaqMan-MGB real-time PCR assay was able to quantitatively amplify the Campylobacter jejuni, Salmonella or Shigella.Appropriate standard amplification curves of Campylobacter jejuni, Salmonella and Shigella in the multiplex quantitative PCR were obtained.The sensitivity of this method was 1×103 ng/μL.There was no false positive detection from other bacterial strains.Conclusions This multiplex quantitative real-time PCR method has good application and development prospects in the detection of microorganisms in tree shrews.
