Osteomyelitis remains difficult to treat, typically requiring a prolonged course of intravenous (IV) antibiotics. The optimal route and duration of antibiotics remains ill-defined due to limited prospective clinical trials. Oritavancin is a long acting, semisynthetic, lipoglycopeptide antibiotic with rapid, concentration-dependent bactericidal activity against many Gram-positive organisms. Read More

Urban Norway rat (Rattus norvegicus) populations can carry the bacteria methicillin-resistant Staphylococcus aureus (MRSA). There are numerous knowledge gaps in the epidemiology of MRSA in these populations that limit understanding of its ecology in urban environments. For example, fecal shedding of MRSA, which may increase environmental contamination, has been reported in other species; however, it is unknown whether Norway rats carry the bacteria rectally.

We have recently shown that a wide range of different inorganic salts can potentiate antimicrobial photodynamic inactivation (aPDI) and TiO2-mediated antimicrobial photocatalysis. Potentiation has been shown with azide, bromide, thiocyanate, selenocyanate, and most strongly, with iodide. Here we show that sodium nitrite can also potentiate broad-spectrum aPDI killing of Gram-positive MRSA and Gram-negative Escherichia coli bacteria. Read More

The development of new ligands that have comparable or enhanced therapeutic efficacy relative to current drugs is vital to the health of the global community in the short and long term. One strategy to accomplish this goal is to functionalize sites on current antimicrobials to enhance specificity and affinity while abating resistance mechanisms of infectious organisms. Herein, we report the synthesis of a series of pyrene-neomycin B (PYR-NEO) conjugates, their binding affinity to A-site RNA targets, resistance to aminoglycoside-modifying enzymes (AMEs), and antibacterial activity against a wide variety of bacterial strains of clinical relevance.
