Genetic diversity and phylogeny of rhizobia isolated from Caragana microphylla growing in desert soil in Ningxia, China

J. Dai, Liu, X., and Wang, Y., Genetic diversity and phylogeny of rhizobia isolated from Caragana microphylla growing in desert soil in Ningxia, China, vol. 11, pp. 2683-2693, 2012.

Rhizobia are soil bacteria with the capacity to induce nitrogen-fixing nodules on the roots or stems of legume plants. A total of 40 bacterial isolates from the root nodules of Caragana microphylla growing in desert soil in Ningxia, China, were analyzed for genetic diversity and phylogenetic position. These isolates were classified into 7 types of 16S ribosomal DNA (rDNA) using polymerase chain reaction-restriction fragment length polymorphism analysis.

Genetic diversity of Burkholderia (Proteobacteria) species from the Caatinga and Atlantic rainforest biomes in Bahia, Brazil

A. C. Santini, Santos, H. R. M., Gross, E., and Corrêa, R. X., Genetic diversity of Burkholderia (Proteobacteria) species from the Caatinga and Atlantic rainforest biomes in Bahia, Brazil, vol. 12, pp. 655-664, 2013.

The genus Burkholderia (β-Proteobacteria) currently comprises more than 60 species, including parasites, symbionts and free-living organisms. Several new species of Burkholderia have recently been described showing a great diversity of phenotypes. We examined the diversity of Burkholderia spp in environmental samples collected from Caatinga and Atlantic rainforest biomes of Bahia, Brazil. Legume nodules were collected from five locations, and 16S rDNA and recA genes of the isolated microorganisms were analyzed.

A description of genes of Corynebacterium pseudotuberculosis useful in diagnostics and vaccine applications

V. D’Afonseca, Moraes, P. M., Dorella, F. A., Pacheco, L. G. C., Meyer, R., Portela, R. W., Miyoshi, A., and Azevedo, V., A description of genes of Corynebacterium pseudotuberculosis useful in diagnostics and vaccine applications, vol. 7. pp. 252-260, 2008.

Corynebacterium pseudotuberculosis, a Gram-positive intracellular pathogen, is the etiological agent of caseous lymphadenitis or CLA. This bacterium infects goats and sheep and causes great economic losses worldwide annually, mainly for goat producers. Despite its importance, CLA is still poorly characterized. However, with advances in the genomic field, many C. pseudotuberculosis genes have already been characterized, mainly those related to virulence such as phospholipase D. Here, we examined the use of the several available genes of C.
