  • Patent number: 8936782
    Abstract: The present invention describes method of treating bacterial infections, including MRSA. In various embodiments, the methods can use interferon beta, which is found to have antimicrobial activity. In certain embodiments, the interferon beta can be human interferon beta. In other embodiments, the interferon beta can be mouse interferon beta. In further embodiments, the interferon beta can be human interferon beta containing amino acid substitutions to make the human interferon beta more cationic in neutral pH.

  • Publication number: 20140205654
    Abstract: The present invention discloses formulations of liposomal vancomycin that are highly effective in the treatment of bacterial infections, and particularly MRSA infections. The present invention further teaches methods of using the formulations disclosed herein for the treatment of bacterial infections. The inventors determined that certain formulations disclosed herein are likely to result in lower toxicity than what is normally associated with vancomycin treatment.

  • Publication number: 20130052162
    Abstract: The present invention demonstrates the important role of C/EBP? in innate immune response against pathogens. Specifically, the inventors showed that in the absence of functional C/EBP?, mice are severely impaired in their ability to clear S. aureus infection. Neutrophils are particularly affected, and susceptibility to S. aureus can be rectified by treatment with interferon-gamma (IFN-?). Importantly, increased activity of C/EBP?, either by induced overexpression of C/EBPE or by application of nicotinamide or an analog, derivative or salt thereof, dramatically enhances immune killing of S. aureus and leads to amelioration of infection.

  • Publication number: 20110251162
    Abstract: The present subject matter relates to pathogenesis of MRSA. Specifically, the present disclosures identifies the pro-inflammatory properties of PVL as the cause of MRSA. Viewed from this new perspective, the present subject matter achieves novel methods and apparatus for treating MRSA infection in a subject involving the administration of an anti-inflammatory drug to the subject. Furthermore the present subject matter teaches methods and apparatus for treating a Panton-Valetine leukocidin associated infection in a subject involving the administration of an anti-inflammatory drug to the subject.

  • Publication number: 20110008303
    Abstract: Described herein are methods for treating and preventing MRSA/MSSA. The present subject matter deviates from current treatment methods by introducing a controlled decolonization/recolonization method, which eradicates the host surface area of MRSA/MSSA, and colonizes the newly cleared surface area with a nonpathogenic or pathogenic bacteria capable of out-competing MRSA/MSSA.
