Infections caused by respiratory pathogens such as Burkholderia cepacia and Pseudomonas aeruginosa are associated with an increased morbidity and mortality in people affected by cystic fibrosis, the most common lethal genetic disease in Caucasian populations. Preventing the acquisition of these pathogens is paramount for these patients. The goal of this survey was to assess the distribution and the prevalence of the measures adopted for the prevention and control of infections caused by respiratory pathogens in the 28 italian centres for cystic fibrosis. 21 questionnaires were returned and some important differences can be observed in the adoption of segregation measures. Although results may be influenced by other factors, specific segregation policies appear to be more directly associated than other measures (e.g., intensive disinfection; behavioural rules to minimise patient' contacts) with lower prevalence of Pseudomonas aeruginosa (OR 0.36 CI95% 0.31-0.42), of multidrug-resistant Pseudomonas aeruginosa (OR 0.30 CI95% 0.22-0.40), and of methicillin-resistant Staphylococcus aureus (OR 0.67 CI95% 0.48-0.94).

A strain positive for the metallo-beta-lactamase gene and resistant to trimethoprim-sulfamethoxazole was unexpectedly isolated from a surveillance rectal swab. The characterization of the strain revealed carriage of a 91 kb integrative and conjugative element (ICE) harboring several resistance determinants [, , , , ∆, , and ], closely related with a group of -type ICEs widespread among and other pseudomonads. Results highlighted the possible spreading of similar elements to , mediating the acquisition of relevant resistances.

Unlabelled: Type IV pili (T4P) are important virulence factors that allow bacteria to adhere to and rapidly colonize their hosts. T4P are primarily composed of major pilins that undergo cycles of extension and retraction and minor pilins that initiate pilus assembly. Bacteriophages use T4P as receptors and exploit pilus dynamics to infect their hosts.

Crystal Violet (CV) is a vibrant and harmful dye known for its toxicity to aquatic life and potential carcinogenic effects on humans. This study explores the removal of CV through photocatalysis driven by visible light, as well as examining the antibacterial and antibiofilm characteristics of zinc oxide nanoparticles (ZnO NPs) synthesized from the aerial roots of Ficus benghalensis. Various characterization techniques were employed to confirm the optical properties, crystal lattices, and morphology of ZnO NPs.

Objectives: To evaluate the antimicrobial susceptibilities of Gram-positive and Gram-negative isolates from patients in Jordan between 2010 and 2021, through the Antimicrobial Testing Leadership and Surveillance (ATLAS) programme.
Methods: Medical centres in Jordan collected bacterial isolates from hospitalised patients with defined infection sources between 2010 and 2021 (no isolates collected in 2014). Antimicrobial susceptibility was interpreted using CLSI standards.
