Acinetobacter baumannii is a nosocomial pathogen of increasing importance due to its multiple resistance antibiotics and ability survive in the hospital environment linked capacity form biofilms. To fully characterize contribution AdeABC, AdeFGH, AdeIJK resistance-nodulation-cell division (RND)-type efflux systems acquired intrinsic resistance, we constructed, from an entirely sequenced susceptible A. strain, set isogenic mutants overexpressing each system following introduction point...
The molecular mechanisms at the origin of eating disorders (EDs), including anorexia nervosa (AN), bulimia and binge-eating disorder (BED), are currently unknown. Previous data indicated that immunoglobulins (Igs) or autoantibodies (auto-Abs) reactive with α-melanocyte-stimulating hormone (α-MSH) involved in regulation feeding emotion; however, such auto-Abs is Here, using proteomics, we identified ClpB heat-shock disaggregation chaperone protein commensal gut bacteria Escherichia coli as a...
The clinical importance of Acinetobacter baumannii is partly due to its natural ability survive in the hospital environment. This persistence may be explained by capacity form biofilms and, interestingly, A. can pellicles at air-liquid interface more readily than other less pathogenic species. Pellicles from twenty-six strains were morphologically classified into three groups: I) egg-shaped (27%); II) ball-shaped (50%); and III) irregular (23%). One strain representative each group was...
Two colistin-susceptible/colistin-resistant (Col(s)/Col(r)) pairs of Acinetobacter baumannii strains assigned to international clone 2, which is prevalent worldwide, were sequentially recovered from two patients after prolonged colistin administration. Compared with the respective Col(s) isolates (Ab248 and Ab299, both having a MIC 0.5 μg/ml), Col(r) (Ab249 Ab347, MICs 128 32 μg/ml, respectively) significantly overexpressed pmrCAB genes, had single-amino-acid shifts in PmrB protein,...
Acinetobacter baumannii has emerged as an opportunistic nosocomial pathogen causing infections worldwide. One reason for this emergence is due to its natural ability survive in the hospital environment, which may be explained by capacity form biofilms. Cell surface appendages are important determinants of A. biofilm formation and such constitute interesting targets prevent development biofilm-related infections. A chemical agent called virstatin was recently described impair virulence Vibrio...
Background Interestingly, Acinetobacter baumannii presents an enhanced capacity to form biofilms (also named pellicles) at the air-liquid interface as compared other species. This characteristic questions contribution of this phenotype increased risk clinical infections by pathogen. Methodology/Principal Findings By a proteomic approach using 2-D gel electrophoresis-LC-MS/MS mass spectrometry, we membrane protein patterns A. 77, pellicle-forming isolate, grown in planktonic and sessile...
The aim of this study was to isolate and characterize new Lactobacillus strains in order check their β-galactosidase activity. A total 28 were isolated from camel goat milks collected the Algerian Sahara. These identified with method Polymerase Chain Reaction (PCR) 16S rRNA gene. Their ability hydrolyze O-nitrophenyl-β-D ga-lactopyranoside (ONPG) determined. Cell lysis involving soni-cation lysozyme treatment used for release strains. Analysis gene sequences revealed that clustered genus, 17...
Bacillus amyloliquefaciens L-17 strain was isolated from a sample of chicken feathers. Here, we report complete genome sequence data B. L-17. The size the is 3,933,788 bp which harbours 4001 coding Sequences. BioProject has been deposited at NCBI GenBank. GenBank accession numbers are PRJNA727793 for BioProject, CP074391.1 chromosome, GCA_018363035.1 assembly and SAMN19035411 BioSample.
