We evaluated trends in Streptococcus pneumoniae antimicrobial susceptibility in United States hospitals in the 2010--2016 period. A total of 8,768 clinical isolates from 47 medical centers were tested for susceptibility by broth microdilution methods. Multidrug-resistant (MDR) and extensively drug-resistant (XDR) rates decreased from 25.7/12.4% (MDR/XDR) in 2010 to 17.7%/3.6% in 2016. Susceptibility to most comparator antimicrobial agents increased, whereas susceptibility to ceftaroline, levofloxacin, linezolid, and tigecycline remained stable...

Spontaneous bacterial peritonitis (SBP) is the most common infection in end-stage liver disease patients. SBP is defined as an ascitic fluid infection with a polymorphonuclear leucocyte count ≥ 250/mm(3) without an evident intra-abdominal surgically treatable source. Several mechanisms contribute to SBP occurrence, including translocation of gut bacteria and their products, reduced intestinal motility provoking bacterial overgrowth, alteration of the gut's barrier function and local immune responses. Historically, Gram-negative enteric bacteria have been the main causative agents of SBP, thereby guiding the empirical therapeutic choice...

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...
