Recovery of Cryptosporidium from spiked water and stool samples measured by PCR and real time PCR
Cryptosporidium parvum is a common intestinal protozoan parasite infecting humans and a wide range of animals, whose diagnostics present considerable difficulties. These arise from the exceptionally robust nature of the oocyst’s walls, which necessitates more stringent treatments for disruption and recovery of DNA for analysis using molecular methods. In the case of water, which is the major so...
متن کاملRapid detection of carbapenemase genes by multiplex real-time PCR.
OBJECTIVES To develop a single multiplex real-time PCR assay to detect six different genetic types of carbapenemases already identified in Enterobacteriaceae (KPC, GES, NDM, IMP, VIM and OXA-48). METHODS A total of 58 bacterial isolates were tested. Thirty were previously characterized as resistant to carbapenems and documented by PCR and sequencing analysis to carry the following genes: bla(...
متن کاملRapid detection of blaKPC carbapenemase genes by real-time PCR.
Carbapenem resistance among Enterobacteriaceae is an emerging problem worldwide. Klebsiella pneumoniae carbapenemase (bla(KPC)) enzymes are among the most common beta-lactamases described. In this study, we report the development and validation of a real-time PCR (q-PCR) assay for the detection of bla(KPC) genes using TaqMan chemistry. The q-PCR amplification of bla(KPC) DNA was linear over 7 l...
متن کاملMulti-centre evaluation of real-time multiplex PCR for detection of carbapenemase genes OXA-48, VIM, IMP, NDM and KPC
BACKGROUND Resistance to carbapenem antibiotics is emerging worldwide among Enterobacteriaceae. To prevent hospital transmission due to unnoticed carriage of carbapenemase producing micro-organisms in newly admitted patients, or follow-up of patients in an outbreak setting, a molecular screening method was developed for detection of the most prevalent carbapenemase genes; blaOXA-48, blaVIM, bla...
متن کاملDevelopment and evaluation of a real-time PCR assay for detection of Klebsiella pneumoniae carbapenemase genes.
We developed a novel real-time PCR assay to detect Klebsiella pneumoniae carbapenemases (KPCs) and used this assay to screen clinical isolates of K. pneumoniae and Klebsiella oxytoca for the presence of bla(KPC) genes. The TaqMan real-time PCR assay amplified a 399-bp product from the bla(KPC) gene. The amplicon was designed so that the genes for isoenzymes KPC-1, -2, and -3 could be easily dis...
