Helicobacter species are fastidious bacterial pathogens that are difficult to culture by standard methods. A PCR-denaturing gradient gel electrophoresis (PCR-DGGE) technique for detection and identification of different Helicobacter species was developed and evaluated. The method involves PCR detection of Helicobacter DNA by genus-specific primers that target 16S rDNA and subsequent differentia...

The 16S rDNA polymerase chain reaction (PCR)-denaturing gradient gel electrophoresis (DGGE) and sequencing method has been demonstrated to be valuable in detecting pathogens in the blood of patients suffering from fever or neutropenia. However, its use in the diagnosis of neonatal late‑onset septicemia (LOS) has not yet been reported. The aim of the present study was to investigate the efficien...

BACKGROUND Candida species are usually opportunistic organisms that cause acute to chronic infections when conditions in the host are favorable. Accurate identification of Candida species is an essential pre-requisite for improved therapeutic strategy. Identification of Candida species by conventional methods is time-consuming with low sensitivity, yet molecular approaches have provided an alte...

Polymerase chain reaction denaturing gradient gel electrophoresis (PCR-DGGE), and a culturedependent technique were used to study the diversity of the intestinal bacterial community in adult Dastarcus helophoroides (Fairmaire) (Coleoptera: Bothrideridae). Universal bacterial primers targeting 200 bp regions of the 16S rDNA gene were used in the PCR-DGGE assay, and 14 bright bands were obtained....

In a survey on the presence of archaea in a number of European lakes, it was found that known archaeal primer sets for PCR were not suited for use in freshwater environment, as some lack selectivity, while others were too selective. A nested PCR was developed for denaturing gradient gel electrophoresis (DGGE) with primer sets 21F-958R and Parch519f-Arch915r, respectively. After sequencing of th...

For many ecological studies of cyanobacteria, it is essential that closely related species or strains can be discriminated. Since this is often not possible by using morphological features, cyanobacteria are frequently studied by using DNA-based methods. A powerful method for analysis of the diversity and dynamics of microbial populations and for checking the purity and affiliation of cultivate...

Multiple endocrine neoplasia type 2 (MEN 2) is an autosomal dominant cancer syndrome caused by mutations in the RET protooncogene. Others have already demonstrated the value of genetic testing in known MEN 2 kindreds. Previously described approaches to DNA-level diagnosis, particularly of index cases, are tedious. We developed appropriate denaturing gradient gel electrophoresis (DGGE) condition...

An annual seasonal cycle of composition of a bacterioplankton community in an oligotrophic coastal system was studied by denaturing gradient gel electrophoresis (DGGE) using five different primer sets. Analysis of DGGE fingerprints showed that primer set 357fGC-907rM grouped samples according to seasons. Additionally, we used the set of 16S rRNA genes archived in the RDPII database to check the...
