Genomic diversity in Staphylococcus xylosus.
Staphylococcus xylosus is a commensal of the skin of humans and animals and a ubiquitous bacterium naturally present in food. It is one of the major starter cultures used for meat fermentation, but a few strains could potentially be hazardous and are related to animal opportunistic infections. To better understand the genetic diversity of S. xylosus intraspecies, suppressive and subtractive hyb...
متن کاملAcute pyelonephritis caused by Staphylococcus xylosus.
Staphylococcus xylosus was recovered from the urine of a patient with pyelonephritis. Antibodies against the teichoic acid of the microorganism were demonstrated in the patient's serum by the agar gel diffusion technique.
متن کاملGlucose kinase-dependent catabolite repression in Staphylococcus xylosus.
By transposon Tn917 mutagenesis, 16 mutants of Staphylococcus xylosus were isolated that showed higher levels of beta-galactosidase activity in the presence of glucose than the wild-type strain. The transposons were found to reside in three adjacent locations in the genome of S. xylosus. The nucleotide sequence of the chromosomal fragment affected by the Tn917 insertions yielded an open reading...
متن کاملAnalysis of catabolite control protein A-dependent repression in Staphylococcus xylosus by a genomic reporter gene system.
A single-copy reporter system for Staphylococcus xylosus has been developed, that uses a promoterless version of the endogenous beta-galactosidase gene lacH as a reporter gene and that allows integration of promoters cloned in front of lacH into the lactose utilization gene cluster by homologous recombination. The system was applied to analyze carbon catabolite repression of S. xylosus promoter...
متن کاملA Staphylococcus xylosus isolate with a new mecC allotype.
Recently, a novel variant of mecA known as mecC (mecA(LGA251)) was identified in Staphylococcus aureus isolates from both humans and animals. In this study, we identified a Staphylococcus xylosus isolate that harbors a new allotype of the mecC gene, mecC1. Whole-genome sequencing revealed that mecC1 forms part of a class E mec complex (mecI-mecR1-mecC1-blaZ) located at the orfX locus as part of...
