  • Patent number: 11957750
    Abstract: An optimized protein-free tripartite vaccine that protects against lethal blood and lung infections caused by a variety of nosocomial pathogens across taxonomic kingdoms, including Gram-positive bacteria, Gram-negative bacteria, and fungi.
    Type: Grant
    Filed: June 22, 2023
    Date of Patent: April 16, 2024

  • Publication number: 20230381157
    Abstract: To identify novel agents to treat carbapenem-resistant Acinetobacter baumannii. the Inventors used a nutrient-depleted medium with serum to mimic the in vivo environment. In RPMI with serum, the screen identified rifabutin (RBT) as being 133-fold more potent than rifampin (RIF) against A. baumannii, with MICs of 0.031 ?g/ml and 4 ?g/ml respectively. No difference in RBT vs. RIF activity was observed when MHII was used as the culture media. RBT possesses markedly superior in efficacy to RIF in murine models of lethal iv and pneumonia models of infection with a hyper-virulent, clinical lung and blood isolate of extreme-drug resistant (XDR) A. baumannii. In both models, RBT significantly improved survival and lowered bacterial burden compared to RIF. RBT is a promising, novel therapeutic option for A. baumannii infections.

  • Publication number: 20230355751
    Abstract: This disclosure provides a new vaccine composition and methods for its use. The composition contains an effective amount of each of: an aluminum hydroxide, a mono-phosphoryl lipid (MPL), and a whole glucan particles (WGP) but no an antigen that raises an immune response against a bacterial or fungal infection.
