A multiplex, real-time TaqMan assay was designed to identify clinical isolates carrying plasmid-mediated ampC genes. The specificity and sensitivity of this assay were 100% when testing characterized AmpC/non-AmpC-producing isolates and randomly selected clinical isolates. This is a rapid assay that can be performed in a clinical microbiology laboratory.

We describe a multiplex real-time PCR assay for use on the ABI 7500 Fast TaqMan platform to detect all currently described Klebsiella pneumoniae carbapenemases (KPC), New Delhi metallo-β-lactamases (NDM), and the OXA-48-like family of carbapenemases from bacterial culture lysates or sample enrichment broth lysates.

Bacteriological culture methods were compared with PCR based protocols (multiplex PCR and TaqMan assay) for the rapid detection of pathogenic Yersinia enterocolitica (YE) in market weight hogs and pork products. The prevalence of YE was compared in lairaged hogs (n=150) versus hogs transported directly to the farm (n=150). By bacteriological culture, YE was not detected in any of the hog tissue...

the objective of this study was to compare the effect of two conventional h9n2 avian influenza (ai) vaccines on replication and shedding of the h9n2 ai virus in broiler chickens. these inactivated oil emulsion vaccines contain either a uae or an iranian h9n2 ai isolate. one hundred and fifty one-day-old commercial broiler chickens were randomly divided into six groups. the birds, except for the...

results our study showed that the sensitivity and specificity of taqman real time pcr was 96% and 95% respectively. these values were 89% and 90, 38% and 100%, 6% and 100% for pcr, culture and microscopy, respectively. conclusions our study showed that sensitivity of taqman real time pcr was higher that pcr, culture and microscopy but specificity of culture and microscopy was more than pcr and ...

We present a multiplex real-time PCR assay for the simultaneous identification of three morphologically similar species of lichen-forming fungi, Lobaria pulmonaria, Lobaria immixta and Lobaria macaronesica. Based on TaqMan MGB (minor groove binding) probes targeting the fungal internal transcribed spacer (ITS nrDNA) region, our assay unambiguously identifies known samples from all the three spe...
