Experimental TherapeuticsIdentification of Antibiotics That Diminish Disease in a Murine Model of Enterohemorrhagic Escherichia coli InfectionInfections with enterohemorrhagic Escherichia coli (EHEC) cause disease ranging from mild diarrhea to hemolytic-uremic syndrome (HUS) and are the most common cause of renal failure in children in high-income countries. The severity of the disease derives from the release of Shiga toxins (Stx). The use of antibiotics to treat EHEC infections is generally avoided, as it...
Editor's Pick Experimental TherapeuticsMechanistic Modeling of Mycobacterium tuberculosis Infection in Murine Models for Drug and Vaccine Efficacy StudiesTuberculosis (TB) drug, regimen, and vaccine development rely heavily on preclinical animal experiments, and quantification of bacterial and immune response dynamics is essential for understanding drug and vaccine efficacy. A mechanism-based model was built to describe Mycobacterium tuberculosis H37Rv infection over time in BALB/c and athymic nude mice, which...
Editor's Pick Experimental TherapeuticsRifabutin Is Active against Mycobacterium abscessus in MiceThere is no reliable cure for Mycobacterium abscessus lung disease. Rifampin is not used clinically due to poor in vitro potency. In contrast, we have shown that rifabutin, another approved rifamycin used to treat tuberculosis, is potent in vitro against M. abscessus. Here, we...
Experimental TherapeuticsAdvancing the Therapeutic Potential of Indoleamides for TuberculosisIndole-2-carboxamide derivatives are inhibitors of MmpL3, the cell wall-associated mycolic acid transporter of Mycobacterium tuberculosis. In the present study, we characterized indoleamide effects on bacterial cell morphology and reevaluated pharmacokinetics and in vivo efficacy using an optimized oral formulation.
PharmacologyPharmacokinetic Data Are Predictive of In Vivo Efficacy for Cefixime and Ceftriaxone against Susceptible and Resistant Neisseria gonorrhoeae Strains in the Gonorrhea Mouse ModelThere is a pressing need for drug development for gonorrhea. Here we describe a pharmacokinetic (PK)/pharmacodynamic (PD) analysis of extended-spectrum cephalosporins (ESC) against drug-susceptible and drug-resistant gonococcal strains in a murine genital tract infection model.
Experimental TherapeuticsEffective Treatment of Mycobacterium avium subsp. hominissuis and Mycobacterium abscessus Species Infections in Macrophages, Biofilm, and Mice by Using Liposomal CiprofloxacinNontuberculous mycobacteria (NTM) affect an increasing number of individuals worldwide. Infection with these organisms is more common in patients with chronic lung conditions, and treatment is challenging.
