(Submitter supplied) Background: Lactococcus garvieae is a bacterial pathogen that affects different animal species and human. Despite the widespread distribution and emerging clinical significance of L. garvieae in both veterinary and human medicine, there is almost a complete lack of knowledge about the genetic content of this microorganism. In the present study the genomic content of L. garvieae CECT 4531 was analyzed by bioinformatic tools and microarray-based comparative genomic hybridizations (CGH) experiments, using Lactococcus lactis subsp. more...

(Submitter supplied) Background Array-based comparative genome hybridization (aCGH) is commonly used to determine the genomic content of bacterial strains. In aCGH data, systematic errors are comparable to those occurring in transcriptome data. However, especially for microbes, an additional source of variation exists: differences in hybridization due to gene sequence divergence between the strains hybridized. Current normalization methods do not take this source of variation into consideration. more...

(Submitter supplied) Streptococcus uberis is one of the principal causative agents of bovine mastitis. The organism is typically considered an environmental pathogen, however, recent studies also suggest possible host adaptation. In this study, two multilocus sequence typing (MLST) schemes and whole genome DNA microarrays were used to evaluate the degree and nature of genome flexibility between S. uberis strains. The 21 isolates examined in this study arise from a collection of 232 international isolates for which previous epidemiological and preliminary genotyping data existed. more...

(Submitter supplied) Pangenome arrays contain DNA oligomers targeting several sequenced reference genomes from the same species. In microbiology these can be employed to investigate the often high genetic variability within a species by comparative genome hybridization (CGH). The biological interpretation of pangenome CGH data depends on the ability to compare strains at a functional level, particularly by comparing the presence or absence of orthologous genes. more...

(Submitter supplied) Lactococcus garvieae has a biopreservative potential against Staphylococcus aureus through its growth inhibition in dairy products. This inhibition involves the production of hydrogen peroxyde by L. garvieae under a high aeration level but little is known about the underlying metabolism. It has already been suggested that this inhibition involves another effector, still unidentified. In this experiment, we aimed to determine the changes in L. more...
