The present invention relates to quaternary ammonium disinfecting cleaner compositions comprising a quaternary ammonium compound, an antimicrobial amine, and an anionic scale inhibitor. Beneficially, the compositions provide sanitizing efficacy without diminished performance and without scale formation when diluted with hard water. The compositions are suitable for inactivating and/or reducing infectious agents, particularly Norovirus, Adenovirus, and Polyomavirus.

Compositions of β-lactam antibiotics and branched poly(ethylenimine) (BPEI), and β-lactam antibiotics and potentiating compounds of polyethylene glycol (PEG)-BPEI conjugates, and methods of their use to treat infections and to remove bacterial biofilms from surfaces of devices and wounds. The BPEI and PEG-BPEI conjugates potentiate the activity of the β-lactam antibiotics so the compositions have synergistic effects against various Gram-positive bacteria. For example, the compositions can be used to treat Gram-positive bacteria, such as Methicillin-resistant Staphylococcus aureus (MRSA) and Methicillin-resistant Staphylococcus epidermidis (MRSE), that have developed resistance against most β-lactam antibiotics. The BPEI and PEG-BPEI conjugates result in the resensitization of such resistant bacterial strains to traditional antibiotic therapies such as β-lactam antibiotics.
