Abstract |
In this study, we describe our newly-developed sensitive two-stage PCR procedure for the detection
of 13 common mycoplasmal contaminants (M. arthritidis, M. bovis, M. fermentans, M. genitalium,
M. hominis, M. hyorhinis, M. neurolyticum, M. orale, M. pirum, M. pneumoniae, M. pulmonis,
M. salivarium, U. urealyticum). For primary amplification, the DNA regions encompassing the
16S and 23S rRNA genes of 13 species were targeted using general mycoplasma primers. The primary
PCR products were then subjected to secondary nested PCR, using two different primer
pair sets, designed via the multiple alignment of nucleotide sequences obtained from the 13 mycoplasmal
species. The nested PCR, which generated DNA fragments of 165-353 bp, was found to
be able to detect 1-2 copies of the target DNA, and evidenced no cross-reactivity with the genomic
DNA of related microorganisms or of human cell lines, thereby confirming the sensitivity and specificity
of the primers used. The identification of contaminated species was achieved via the performance
of restriction fragment length polymorphism (RFLP) coupled with Sau3AI digestion.
The results obtained in this study furnish evidence suggesting that the employed assay system
constitutes an effective tool for the disagnosis of mycoplasmal contamination in cell culture
systems. |
