Disclosed herein include methods, compositions, and kits suitable for use in dynamic non-destructive imaging. The non-destructive imaging can be nonlinear ultrasound imaging. There are provided, in some embodiments, nucleic acid compositions encoding gas vesicles (GVs) capable of producing nonlinear ultrasound contrast upon expression in a prokaryotic cell (e.g., a probiotic bacterial cell) or a eukaryotic cell (e.g., a therapeutic mammalian cell).

Methods of and compositions for breaking down a biofilm or inhibiting, preventing or treating a microbial infection that produces a biofilm are disclosed, which involves administration of an interfering agent capable of specifically competing, titrating, or inhibiting the binding of an HU protein to a microbial DNA. By competing with HU proteins that bind to DNA scaffold in the biofilm, these interfering agents destabilize the biofilm leading to destruction and removal of the biofilm by the immune system. Further method and composition aspects are contemplated in relation to infections caused by bacteria that export an HU protein.
