Sézary syndrome (SS) is an aggressive type of cutaneous T-cell lymphoma. Diagnosing SS can be challenging, especially in early stages disease. Previously, a genome-wide study, we showed that promoter hypermethylation PROM1, G0S2, CMTM2, PAM, GNMT and NEXN frequently observed late disease, but neither found healthy donors nor benign erythrodermic inflammatory dermatoses (EID) patients. In this e...

To differentiate the Borrelia burgdorferi sensu lato genospecies, LightCycler real-time PCR was used for the fluorescence (SYBR Green I) melting curve analysis of borrelial recA gene PCR products. The specific melting temperature analyzed is a function of the GC/AT ratio, length, and nucleotide sequence of the amplified product. A total of 32 DNA samples were tested. Of them three were isolated...

In a recently published article, Fukushima et al. (3) described a novel PCR-melting curve analysis (PCR-MCA) method for rapid screening of the most prevalent point mutations related to fluoroquinolone resistance in Streptococcus pneumoniae. In their study, they included 22 levofloxacin (LVX)-resistant strains and 50 LVX-susceptible isolates. None of the isolates in that study were shown to harb...

BACKGROUND Most PCR assays for detection of 5-methylcytosine in genomic DNA entail a two-step procedure, comprising initial PCR amplification and subsequent product analysis in separate operations that usually require manual transfer. These methods generally provide information about methylation of only a few CpG dinucleotides within the target sequence. METHODS An in-tube methylation assay i...
