Particle delivery via small-scale morphology materials for antibacterial applications

Disclosed herein is a particle delivery system comprising electrospun nanofiber comprised of coaxial fiber with a microfluidic core. Iron-doped apatite nanoparticles (IDANPs) have demonstrated a unique influence over phage killing of bacteria, whereby, IDANP-exposed bacterial cultures experience 2× the bacterial death as controls. IDANPs consist of hydroxyapatite (HA) doped with iron. HA is a mineral known to be biocompatible and analogous to the inorganic constituent of mammalian bone and teeth and has been approved by the Food and Drug Administration (FDA) for many applications in medicine and dentistry. Previous work has shown that for IDANPs to enhance antibacterial activity of phage to the greatest extent, bacterial cultures should be exposed to IDANPs for 1 hr prior to phage introduction. Biocompatible polymer materials which encase IDANPs and/or phage can be used to disseminate IDANPs and/or phage in a controlled manner into a physiological system for treatment of bacterial infection. When components of said materials contain micro- or nano-scale components, high surface-to-volume ratio for treatment delivery is garnered.

METHODS FOR USING ANTIMICROBIAL COMPOSITIONS
20210368788 · 2021-12-02 ·

A composition that can be used to treat a wide spectrum of gram positive and gram negative bacteria, including but not limited to those in biofilm form, and other microbes can be used in cilia-containing areas such as the sinus cavities and middle/inner ear, while resulting in no, or very minimal amounts of, deciliation. Where such a targeted treatment area includes a biofilm, the composition often can detach and assist in removing the biofilm from affected tissue. Many embodiments of the composition are biocompatible.

Methods of treating <i>Pseudomonas aeruginosa </i>respiratory infections

Pseudomonas aeruginosa (PA) leads to chronic respiratory infections especially in patients with cystic fibrosis patients and chronic obstructive pulmonary disease (COPD), characterized by a high morbidity. After screening Lactobacilli coming from CF expectoration, on their capacity to inhibit two Pseudomonas aeruginosa (PA) virulence factors (elastase, pyocyanin), the inventors evaluated the effect of intranasal administration of Lactobacilli on PA murine pneumonia. The primary outcome was the bacterial lung load 24 hours after PA induced pneumonia. To understand the role of Lactobacillus, the chemokines, the pro and anti-inflammatory BAL rates were also measured. The administration of Lactobacilli cocktail 18 h prior the PA lung infection decreases significantly the lung bacterial load at 24 h post-infection. Although the mechanisms need to be deeply explored, an immunomodulation effect may be involved, notably through the recruitment of neutrophils. Thus the present relates to a method of treating a Pseudomonas aeruginosa respiratory tract infection in a patient in need thereof comprising administering to the patient's respiratory tract a therapeutically effective amount of at least one Lactobacillus strain.
