MDROs, or Multidrug-Resistant Organisms, are pathogens that have acquired resistance to multiple antimicrobial drugs. These organisms are capable of causing various infections that are difficult to treat due to their resistance to standard treatments. Common examples of MDROs include Methicillin-Resistant Staphylococcus aureus (MRSA), Vancomycin-Resistant Enterococci (VRE), and certain strains of Klebsiella pneumoniae.
