Recreational Facilities as Reservoirs for Multidrug-Resistant Staphylococcus aureus.

Antibiotic-resistant pathogens in public settings present a growing risk to human health. Staphylococcus aureus often asymptomatically colonizes human skin, while virulent strains cause soft tissue infections, osteomyelitis, endocarditis, and are associated with cystic fibrosis. Here we investigated the presence and distribution of multidrug-resistant S.

activity of gepotidacin and comparator antimicrobials against isolates of nontuberculous mycobacteria (NTM).

Novel antimicrobials are needed to treat rising nontuberculous mycobacteria (NTM) infections. Using standard broth microdilution methods, 68 NTM isolates were tested against gepotidacin, a new, first-in-class, oral triazaacenaphthylene bacterial topoisomerase inhibitor. MICs varied (0.

In vitro activity of gepotidacin against urine isolates of Escherichia coli from outpatient departments in Germany.

Background: Escherichia coli is the leading pathogen of community-acquired urinary tract infections. Gepotidacin is a novel, bactericidal, first-in-class triazaacenaphthylene oral antibiotic that inhibits bacterial DNA replication by a distinct mechanism of action that confers activity against most strains of target pathogens, such as E. coli, Staphylococcus saprophyticus and Neisseria gonorrhoeae, including those resistant to other antibiotics.

Augmented antibacterial activity of ampicillin with silver nanoparticles against methicillin-resistant Staphylococcus aureus (MRSA).

At present, including failed attempts, it takes about 15 years and costs totaling up to $2.6 billion to take a promising new compound from laboratory to the market. Increasing drug resistance among microbial pathogens has led to a growing interest in exploring novel methods to enhance the efficacy of existing drugs.

Prediction of fathead minnow acute toxicity of organic compounds from molecular structure.

Interest in the prediction of toxicity without the use of experimental data is growing, and quantitative structure-activity relationship (QSAR) methods are valuable for such predictions. A QSAR study of acute aqueous toxicity of 375 diverse organic compounds has been developed using only calculated structural features as independent variables. Toxicity is expressed as -log(LD(50)) with the units -log(millimoles per liter) and ranges from -3 to 6.
