We have developed a singletube real-time polymerase chain reaction (PCR) assay for rapid detection of Mollicutes species stipulated by the European Pharmacopeia. METHODS: Primers and TaqMan probes (FAM- abeled) were deduced from 16S rDNA sequence alignment of 18 mollicutes species. A synthetic internal control (IC) DNA and an IC-specific TaqMan probe (VIC-labeled) were included. The analytical sensitivity of the assay was determined on DNA dilutions from 12 mollicute strains. Specificity was proven by the use of DNA from other bacteria. RESULTS: Analytical sensitivities of the PCR assay were in the range of 405–2,431 genomes/ml for 11 of the 12 tested mollicute DNA samples. The lowest sensitivity was found for Ureaplasma urealyticum (19,239 genomes/ml). Negative results for DNA samples from 3 different ubiquitous bacteria demonstrated the specificity of the PCR assay for Mollicutes. Direct testing of cell culture supernatants spiked with Mycoplasma orale revealed similar sensitivity compared to isolated DNA. CONCLUSION: Our single-tube real-time PCR assay with internal reaction control enables rapid and specific detection of mollicute contaminants. The test protocol is suitable for routine quality control of cell therapeutics. date: 2014 publisher: Karger id_scheme: DOI id_number: 10.11588/heidok.00027237 official_url: https://doi.org/10.1159/000357096 ppn_swb: 1680086545 own_urn: urn:nbn:de:bsz:16-heidok-272378 language: eng bibsort: JANETZKOKAASINGLETUB2014 full_text_status: public publication: Transfusion Medicine and Hemotherapy volume: 41 number: 1 place_of_pub: Basel ; Freiburg pagerange: 83-89 issn: 1660-3796 (Druck-Ausg.), 1660-3818 (Online-Ausg.) citation: Janetzko, Karin ; Rink, Gabi ; Hecker, Andrea ; Bieback, Karen ; Klüter, Harald ; Bugert, Peter (2014) A Single-Tube Real-Time PCR Assay for Mycoplasma Detection as a Routine Quality Control of Cell Therapeutics.
