Detection of diverse new Francisella-like bacteria in environmental samples

Article Abstract:

Soil and water samples are analyzed for the presence of Francisella-like DNA sequences to follow up the detection of putative Francisella tularensis in Houston, Texas. A nested approach is employed, using PCR primer sets of increasing specificity to detect and identify Francisella sequences present in DNA extract from the samples.

Acidobacteria phylum sequences in uranium-contaminated subsurface sediments greatly expand the known diversity within the phylum

Article Abstract:

The abundance and composition of bacteria of the phylum Acidobacteria surveyed in subsurface sediments from uranium-contaminated sites using amplification of 16S rRNA genes followed by clones/sequence analysis produced a revised and greatly expanded phylogeny of the Acidobacteria phylum consisting of 26 subgroups.

Fine-scale genetic diversity among Burkholderia pseudomallei soil isolates in northeast Thailand

Article Abstract:

Burkholderia pseudomallei soil isolates from northeast Thailand are genotyped using multiple-locus variable number tandem repeat analysis (MLVA) and multilocus sequence typing (MLST). MLVA identified 19 genotypes within three clades, while MLST revealed two genotypes.
