Pseudoxanthomonas
Description and Significance
Pseudoxanthomonas winnipegensis is a gram negative bacteria. This species obtains the bacillus shape and has a yellowish pigment. Pseudoxanthomonas winnipegensis was derived water, plants or contaminated soils. Recent studies recovered the bacteria from human clinical materials and was recently recovered from cystic fibrosis patients. Until recently, Pseudoxanthomonas species were only identifiable at the genus level. New gene sequencing improvements have allowed for the identification of species within the genus.
Genome Structure
Describe the size and content of the genome. How many chromosomes? Circular or linear? Other interesting features? What is known about its sequence?
Specific strains of this bacteria were studied by whole genome sequencing which used average nucleotide identity, DNA-DNA hybridization, amino acid identity, core genome and nucleotide analyses, biochemical and cellular fatty acid analysis and antimicrobial susceptibility testing. Pseudoxanthomonas winnipegenesis structure was investigated using scanning microscopes and transmission electron microscopes. The bacteria was found to be a gram-negative bacilli.
Bacteria were studied by whole genome sequencing using average nucleotide identity by Blastn, digital DNA-DNA hybridization, average amino acid identity, core genome and single nucleotide variant analyses, MALDI-TOF, biochemical and cellular fatty acid analyses, and by antimicrobial susceptibility testing. Bacterial structures were assessed using scanning and transmission electron microscopy. Strains were strict aerobes, yellowish-pigmented, oxidative, non-motile, Gram-stain-negative bacilli and generally unable to reduce nitrate. Strains were susceptible to most of the antibiotics tested; some resistance was observed towards carbapenems, several cephems and uniformly to nitrofurantoin. The single taxon group observed by 16S rRNA gene sequencing was supported by whole genome sequencing; genomes ranged in size from 4.36 to 4.73 Mb and had an average G+C content of 69.12 mol%
