P. aeruginosa wound infection was induced in white mice to test new preparations against P. aeruginosa. This model ensures the nearest approximation to the course of P. aeruginosa chronic infection, i.e. it reproduces the focus of inflammation and the prolonged course of the disease (the positive decision on application No. 4, 324, 555 of November 2, 1987, has been obtained). The essence of the method consists in obtaining the model of P. aeruginosa wound infection by a combined trauma of the skin (burn and incision): P. aeruginosa is introduced in a dose of 6 X 10(9)-8 X 10(9) microbial cells into the burn blister through the incision made 3 hours after the burn and then 20-24 hours later in a dose of 10(9)-2 X 10(9) microbial cells, introduced under the crust formed by that time.

Recurrent Bacteremia in the Setting of Pseudomonas Endocarditis of the Tricuspid Valve and Indwelling Medical Devices.
Cureus
December 2024
Internal Medicine, Cooper University Hospital, Camden, USA.
This case report presents a complex and challenging scenario of recurrent () bacteremia and tricuspid valve endocarditis in a 77-year-old male patient with multiple comorbidities and indwelling medical devices. The patient's medical history was significant for T4 paraplegia, neurogenic bladder requiring a chronic indwelling suprapubic catheter, heart block status post-permanent pacemaker placement, type 2 diabetes mellitus, chronic kidney disease, and chronic sacral wounds. The case highlights the difficulties in managing antibiotic-resistant infections, particularly in patients with implantable devices and chronic wounds.

Wound healing is a complex physiological process, with scarring and infection caused by and being the most common complications. The reutilization of known medications has received increased attention for their role in cell function as small molecules. Examples of these include lovastatin, a cholesterol-lowering agent, and resveratrol, which have multiple biological properties.

: Chronic wounds, including hidradenitis suppurativa (HS) and venous ulcers (VU), are commonly associated with complex microbial communities that may influence wound healing and treatment outcomes. Understanding microbial diversity and antibiotic resistance patterns is essential in order to optimize therapeutic strategies. This study aimed to investigate the microbial populations and antibiotic resistance profiles in HS and VU patients, comparing the prevalence of common pathogens and their antimicrobial resistance profiles.

Background/objectives: rapidly acquires antibiotic resistance and demonstrates increasing tolerance to antiseptics. This study evaluated the activity of eight antiseptics against , assessed its ability to develop adaptation to these antiseptics, and, for the first time, determined the Karpinski Adaptation Index (KAI) for this bacterium.
Methods: The minimal inhibitory concentration (MIC), susceptibility to antibiotics, bactericidal time according to EN 1040:2005, adaptation potential, and KAI of strains were evaluated.
Exploring Methacrylated Gellan Gum 3D Bioprinted Patches Loaded with Tannic Acid or L-Ascorbic Acid as Potential Platform for Wound Dressing Application.

Institute of Polymers, Composites and Biomaterials (IPCB), National Research Council (CNR), 80125 Naples, Italy.
To improve wound healing, advanced biofabrication techniques are proposed here to develop customized wound patches to release bioactive agents targeting cell function in a controlled manner. Three-dimensional (3D) bioprinted "smart" patches, based on methacrylated gellan gum (GGMA), loaded with tannic acid (TA) or L-ascorbic acid (AA) have been manufactured. To improve stability and degradation time, gellan gum (GG) was chemically modified by grafting methacrylic moieties on the polysaccharide backbone.
