BACKGROUND: Dog bites are a frequent injury, but the incidence and type of lesions vary across countries. Although only few patients develop complications, the treatment of advanced injuries has a considerable medical, social and economic impact. A frequently isolated pathogen in dog bite wounds is Capnocytophaga canimorsus, a bacterium that can cause sepsis or meningitis. Hyperbaric oxygen (HBO₂) therapy has been shown to be useful in treating anaerobic infections, most likely because it creates an inhospitable environment for the bacterium and enhances the patient's immune response...

Meticillin-resistant Staphylococcus aureus (MRSA) continues to be a major public health problem. Vancomycin and teicoplanin have been in clinical use for several decades but their drawbacks are well described. In the last 10 years several antibiotics have been made available for clinical use. Daptomycin and linezolid have been extensively used during this period. Other agents such as ceftaroline, ceftobiprole, dalbavancin, oritavancin, tedizolid, and telavancin have been approved by regulatory agencies since 2009...

We evaluated trends in Staphylococcus aureus antimicrobial susceptibility in United States hospitals in the 2010-2016 period. A total of 21,056 clinical isolates from 42 medical centers were tested for susceptibility by broth microdilution methods. MRSA rates decreased from 50.0% (2010) to 42.2% (2016). Susceptibility to erythromycin, levofloxacin, and clindamycin increased slightly, whereas susceptibility to ceftaroline, trimethoprim-sulfamethoxazole, and tetracycline remained stable. Ceftaroline retained potent activity against MSSA and MRSA (97...

Certain Staphylococcus aureus strains exhibit an inoculum effect (InE) with cefazolin (CFZ) that has been associated with therapeutic failures in high-inoculum infections. We assessed the in vitro activities of ceftaroline (CPT), CFZ, and nafcillin (NAF) against 17 type A β-lactamase (βla)-producing, methicillin-susceptible S. aureus (MSSA) strains, including the previously reported TX0117, which exhibits the CFZ InE, and its βla-cured derivative, TX0117c. Additionally, we determined the pharmacokinetics of CPT in rats after single intramuscular doses of 20 and 40 mg/kg of body weight and evaluated the activities of CPT (40 mg/kg every 8 h [q8h]), CFZ, and NAF against TX0117 and TX0117c in a rat model of infective endocarditis...

Objectives: Among viridans group streptococcal infective endocarditis (IE), the Streptococcus mitis group is the most common aetiological organism. Treatment of IE caused by the S. mitis group is challenging due to the high frequency of β-lactam resistance, drug allergy and intolerability of mainstay antimicrobial agents such as vancomycin or gentamicin. Daptomycin has been suggested as an alternative therapeutic option in these scenarios based on its excellent susceptibility profile against S...

Background.: A second-sign prospective restriction of select broad-spectrum antimicrobials was fully implemented in January 2015 as a pediatric antimicrobial stewardship program (ASP) initiative to help ensure the most appropriate empiric use of ceftaroline, cefepime, fidaxomicin, linezolid, and vancomycin (intravenous). The objective of this evaluation is to assess the effectiveness of a forced second-sign process in the electronic medical record as a pediatric ASP strategy. We anticipated that the second-sign process for antibiotics would increase the appropriateness of empiric antibiotic use, as defined by preapproved criteria, clinical pathways, national guidelines, and pediatric-specific infectious diseases reference texts, while not causing significant delay in the initial administration of antibiotic therapy...
