This study confirms that Taq DNA polymerase could be contaminated with the blaTEM-1(a) gene. It also proposes two different methods that could be used to overcome DNA contamination: (i) DNase I treatment prior to PCR amplification; and (ii) the use of a highly purified Taq DNA polymerase which was devoid of detectable contamination.

    ABSTRACT: Among 53 Acinetobacter baumannii isolates collected in 2004, nine imipenem-resistant isolates were obtained from clinical specimens taken from patients hospitalized in Busan, Korea. Nine carbapenemase-producing isolates were further investigated in order to determine the mechanisms underlying resistance. These isolates were then analyzed via antibiotic susceptibility testing, microbiological tests of carbapenemase activity, pI determination, transconjugation test, enterobacterial repetitive consensus (ERIC)-PCR, and DNA sequencing. One outbreak involved seven cases of infection by A. baumannii producing OXA-23 beta-lactamase, and was found to have been caused by a single ERIC-PCR clone. During the study period, the other outbreak involved two cases of infection by A. baumannii producing IMP-1 beta-lactamase. The two clones, one from each of the outbreaks, were characterized via a modified cloverleaf synergy test and an EDTA-disk synergy test. The isoelectric focusing of the crude bacterial extracts detected nitrocefin-positive bands with pI values of 6.65 (OXA-23) and 9.0 (IMP-1). The PCR amplification and characterization of the amplicons via direct sequencing showed that the clonal isolates harbored blaIMP-1 or blaOXA-23 determinants. The two clones were characterized by a multidrug resistance phenotype that remained unaltered throughout the outbreak. This resistance encompassed penicillins, extended-spectrum cephalosporins, carbapenems, monobactams, and aminoglycosides. These results appear to show that the imipenem resistance observed among nine Korean A. baumannii isolates could be attributed to the spread of an IMP-1- or OXA-23-producing clone. Our microbiological test of carbapenemase activity is a simple method for the screening of clinical isolates producing class D carbapenemase and/or class B metallo-beta-lactamase, in order both to determine their clinical impact and to prevent further spread.

    ABSTRACT: PCR detection of microbial pathogens in blood from patients is a promising issue for rapid diagnosis of sepsis and early targeted therapy. However, for PCR assays detecting all bacterial groups, broad range primers, in particular the 16S rDNA targeting primers have to be used. Upcoming false signals and reduced sensitivity are a common problem as a consequence of unspecific amplification reactions with the human DNA background. Here we show that, using total DNA extracts from blood, unspecific signals occurred in general 16S rDNA PCRs as a result of the amplification of human sequences. To address this problem, we developed a protocol by which the human background DNA is removed and bacterial DNA is enriched during sample preparation, a method we termed background-free enrichment method (BFEM). In general, we aimed to exclude false signals due to the human background DNA yielded from 16S rDNA PCR, Real-Time-PCR and IGS-PCR analyses. We applied the BFEM to the analysis of blood samples from 22 patients and obtained results similar to standard blood culture methods. The BFEM allows specific and sensitive detection of pathogens in downstream PCR assays and is easy to handle due to the quick sample preparation procedure. Thus, the BFEM contributes to the generation of replicable and more reliable data in general 16S rDNA PCR assays.
