ABSTRACT
Objective Aiming at detecting Staphylococcus aureus、Pseudomonas aeruginosa and Klebsiella pneumoniae in laboratory animals,the paper provides a rapid,sensitive and simple test method.Methods According to Staphylococcus aureus nuc gene,Pseudomonas aeruginosa LasI gene,Klebsiella pneumonia PhoE gene and general 16S rRNA gene, designed specific primers;Through the optimization of multiplex PCR primer concentrations and annealing temperature, the specificity and sensitivity of detection, establishing multiplex PCR system.Application of the PCR system test specimens of artificial infections and experiment animal feces is compared with traditional test method.Results Multiplex PCR amplification of Staphylococcus aureus (153 bp), Pseudomonas aeruginosa (600 bp) with Klebsiella pneumoniae (368 bp) and general (520 bp).The multiplex sensitivity for the purpose of 10pg, specificity of detection was not detected from other pathogens.Application of establishing multiplex PCR system to detect the artificial positive samples, and detect 1 Pseudomonas aeruginosa positive case in 76 fecals.Conclusions This paper established the multiplex PCR method which has the advantages of specific,sensitive,simple and rapid, and provides a reliable way for rapid test in laboratory animals microbiology.
