The SulA protein of Escherichia coli and related bacteria interacts directly with FtsZ, blocking cell division by disrupting Z-ring formation, yet the precise mechanism remains not fully understood. Previous demonstrations of Pseudomonas aeruginosa SulA's dimerization capability were confined to X-ray crystallography and lacked confirmation under in vivo conditions. Additionally, uncertainty persisted regarding the dimerization potential of E. coli's SulA protein. This paper employs a bacterial two-hybrid system to establish that both P. aeruginosa and E. coli SulA proteins indeed possess the capacity for dimerization.

Background: A wound must progress through serial steps of healing to achieve structural and functional stability. This process is hampered in chronic wounds and wounds with delayed healing. Wound cover through skin grafting or a flap, or spontaneous healing through epithelization, requires healthy granulation tissue.

Cellular senescence, a complex biological process resulting in permanent cell-cycle arrest, is central to aging and age-related diseases. A key concept in understanding cellular senescence is the Hayflick Limit, which refers to the limited capacity of normal human cells to divide, after which they become senescent. Senescent cells (SC) accumulate with age, releasing pro-inflammatory and tissue-remodeling factors collectively known as the senescence-associated secretory phenotype (SASP).

Purpose: Preclinical studies have confirmed the safety and efficacy of narrowband low-intensity ultraviolet C light (UVC) in managing bacterial corneal infection. To further consolidate these findings, the present study aimed to explore in vitro anti-biofilm efficacy of low-intensity UVC light for its potential use in biofilm-related infections.
Methods: Pseudomonas aeruginosa biofilm was grown in chamber well slides for 48 h and exposed to one of the following challenges: UVC (265 nm wavelength, intensity 1.

Pseudomonas aeruginosa is an opportunistic pathogen belonging to the γ-proteobacteria family, known to cause pneumonia linked with ventilator use and nosocomial infections. With the increasing prevalence of antibiotic-resistant bacteria, there is a pressing need to identify alternatives to conventional antibiotics. Plant-derived substances (PDSs) offer potential not only as antibacterial agents but also as modulators of antibiotic resistance.

Objectives: To evaluate the in vitro susceptibility of recent Gram-negative pathogens collected from pediatric patients to imipenem/relebactam (IMI/REL) and comparator agents.
Methods: From 2018 to 2022, 254 hospitals in 62 countries collected Enterobacterales or P. aeruginosa isolates from patients <18 years old as part of the SMART global surveillance program.
