The present investigation has revealed the possibility of using different kinds of monodispersed polystyrene latex, produced in the USSR, as carriers in the process of the preparation of antibody diagnosticums intended for the detection of water-soluble slime antigens of Pseudomonas aeruginosa strains belonging to the most widespread serological types. The optimum conditions for the preparation of latex reagents and for making the latex-agglutination test have been experimentally established. The new diagnosticums+ have been shown to be highly species- and type-specific, which permits making judgment on the presence or absence of slime antigens of P. aeruginosa strains belonging to definite serovars in the clinical material under study. The preparations thus obtained have been found to retain their sensitivity for 16 months (the term of observation).

Lipases, enzymes that perform the hydrolysis of triglycerides into fatty acids and glycerol, present a potential paradigm shift in the realms of food and detergent industries. Their enhanced efficiency, energy conservation and environmentally friendly attributes make them promising substitutes for chemical catalysts. Motivated by this prospect, this present study was targeted on the heterologous expression of a lipase gene, employing E.

Objectives: In Pseudomonas aeruginosa isolates, emerging meropenem resistance beyond imipenem resistance has become a problem. In this study, we aimed to investigate the relationship between the in vivo acquisition of antimicrobial resistance in fluoroquinolone- and carbapenem-resistant P. aeruginosa clinical isolates, the underlying molecular mechanisms, and exposure to antimicrobial agents.

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.
