Peripherally-restricted recurrent infection by engineered E. coli strain modulates hippocampal proteome promoting memory impairments in a rat model.

Commensal bacteria that breach endothelial barrier has been reported to induce low grade chronic inflammation producing disease symptoms in major peripheral tissues. In this study, we investigated the role of genetically modified cellular invasive form of commensal E. coli K12 (SK3842) in cognitive impairment.

Functional Amyloids in Pseudomonas aeruginosa Are Essential for the Proteome Modulation That Leads to Pathoadaptation in Pulmonary Niches.

Persistence and survival of Pseudomonas aeruginosa in chronic lung infections is closely linked to the biofilm lifestyle. One biofilm component, functional amyloid of P. aeruginosa (Fap), imparts structural adaptations for biofilms; however, the role of Fap in pathogenesis is still unclear.

Designing multi-epitope vaccine candidates against functional amyloids in Pseudomonas aeruginosa through immunoinformatic and structural bioinformatics approach.

Pseudomonas aeruginosa (P. aeruginosa) displays high drug resistance and biofilm-mediated adaptability, which makes its infections difficult to treat. Alternative intervention methods and targets have made such infections treatment manageable.

Motifs and interface amino acid-mediated regulation of amyloid biogenesis in microbes to humans: potential targets for intervention.

Amyloids are linked to many debilitating diseases in mammals. Some organisms produce amyloids that have a functional role in the maintenance of their biological processes. Microbes utilize functional bacterial amyloids (FuBA) for pathogenicity and infections.

Exploring bacterial resistome and resistance dessemination: an approach of whole genome sequencing.

For several decades antibiotics are used to combat against pathogenic bacteria, but their misuse and overuse have caused the emergence of resistant bacteria. The scarcities of effective antibiotics along with unavailability of alternative solutions have exacerbated bacterial infections and mortality rate. This review provides the concept of bacterial resistome and mechanisms of resistance.

Genome analyses of carrying ST 315 isolate from sewage water of one of the Indian hospitals.

Background: Emergence of carbapenem resistant pathovars and their environmental dissemination are alarming problems. isolated from sewage water of hospital setting conferred a high resistance towards β-lactams, particularly towards carbapenem. This prompted us to perform whole genome sequence analysis to investigate the antimicrobial determinants, pathogenicity status and mobile genetic elements associated with resistance genes.

Draft Genome Sequence of the First NDM-4-Producing Strain (AK1), Isolated from Sewage Water of a North Indian Hospital.

We report here the draft genome sequence of the first isolated NDM-4-producing strain, isolated from sewage water at a North Indian hospital. The genome has an assembly size of 5,076,053 bp, arranged in 129 contigs, with 5,271 genes and a G+C content of 50.47%.

Ascorbic acid inhibits human insulin aggregation and protects against amyloid induced cytotoxicity.

Protein aggregation into oligomers and fibrils are associated with many human pathophysiologies. Compounds that modulate protein aggregation and interact with preformed fibrils and convert them to less toxic species, expect to serve as promising drug candidates and aid to the drug development efforts against aggregation diseases. In present study, the kinetics of amyloid fibril formation by human insulin (HI) and the anti-amyloidogenic activity of ascorbic acid (AA) were investigated by employing various spectroscopic, imaging and computational approaches.
