COMPOSITIONS AND METHODS FOR MITIGATING DRUG RESISTANT BACTERIA
The current invention is a broad-based remediation mechanism against MRFs and includes nanotechnology formulations and methodologies that may be used to develop novel mitigation strategies against certain drug resistant bacterial strains. In an embodiment, the current invention relates to mitigation of drug resistant bacteria from nosocomial infections, for example in hospitals and in food animals. The invention uses hybrid nanomaterials comprising oligo-chitosan and zinc oxide formulated as nanoparticles and micelles. The inventors unexpectedly found unique properties of very small oligomers of chitosan that effectively mitigate MRFs- and Vancomycin-Resistant Enterococcus (VRE)-induced illnesses without compromising the balance of the beneficial flora in the abdomen. Also, the combination of chitosan with zinc oxide demonstrated synergistic and unexpected effects in remediation of important food-borne bacteria including the resistant types.
