Pneumococcus morphogenesis and resistance to beta-lactams

, 2014
Streptococcus pneumoniae, le pneumocoque, est une bactérie pathogène qui entraîne le décès de plus d'un million et demi de personnes dans le monde chaque année. Les β-lactamines sont très utilisées pour traiter les infections à pneumocoques. Ces antibiotiques inhibent la synthèse du peptidoglycane, une molécule géante constituant un réseau de chaînes ...

The Burden of Antimicrobial‐Resistant Pseudomonas aeruginosa Isolates in Children With Cystic Fibrosis: Molecular Characterization and Genotyping Analysis

MicrobiologyOpen, Volume 15, Issue 1, February 2026.
This study highlights the prevalence of multidrug‐ and carbapenem‐resistant Pseudomonas aeruginosa in pediatric cystic fibrosis patients, along with the presence of carbapenemase‐encoding genes and genetic profiles, suggesting clonal spread. These findings underscore the urgent need for surveillance and strategies to combat resistant strains and ...

Antibiotic Resistance, Biofilm Genes, and smeDEF Efflux Pump in Clinical Stenotrophomonas maltophilia Isolates From Iran

MicrobiologyOpen, Volume 15, Issue 1, February 2026.
Iranian clinical Stenotrophomonas maltophilia isolates showed high susceptibility to trimethoprim/sulfamethoxazole, minocycline, and levofloxacin, but marked resistance to ceftazidime and ticarcillin‐clavulanate, alongside widespread biofilm production and resistance genes.

The Role of the Gut Microbiome in the Complex Network of Frailty Syndrome and Associated Comorbidities in Aging

Aging Cell, Volume 25, Issue 2, February 2026.
This study analyzed gut microbiota in older adults with and without Frailty Syndrome by 16S rRNA gene sequencing and metagenomics. Frailty was associated with altered microbial composition, metabolic functions, and increased antimicrobial resistance, whereas non‐frail individuals showed healthier profiles.
