Introduction : When treating periprosthetic joint infection with a two-stage procedure, antibiotic-impregnated spacers can be used in the interval between prosthetic removal and reimplantation. In our experience, cultures of sonicated spacers are most often negative. The objective of the study was to assess whether that sonication causes an elution of antibiotics, leading to elevated antibiotic concentrations in the sonication fluid inhibiting bacterial growth and thus causing false-negative cultures. Methods : A prospective monocentric study was performed from September 2014 to March 2016...

Exposure to environmental geogenic (or earth-derived) dust can lead to more frequent and severe infections in the human airway. Particulate matter < 10 µm (PM10 ) is the component of air pollution that is commonly associated with the exacerbation of respiratory diseases. We have previously demonstrated that mice exposed to geogenic dust PM10 experienced an exacerbation of inflammatory responses to influenza A virus. Whether geogenic dust PM10 also exacerbates respiratory bacterial infection is not yet known, nor are the components of the dust that drive these responses...

BACKGROUND: Infected joint replacements can be treated with gentamicin-containing materials for implantation. This may lead to side effects, especially in patients with impaired renal function. CASE DESCRIPTION: A 74-year-old woman underwent two surgeries for an acutely infected hip replacement. Gentamicin sponges (Garacol) were implanted during both interventions. The day after the second operation, her serum gentamicin levels had risen to toxic values. This confirmed the suspicion that she had a kidney impairment which was probably caused by the implanted gentamicin-containing sponges...

The aminoglycoside antibiotics, discovered as natural products in the 1940s, demonstrate a broad anti-microbial spectrum. Due to their nephrotoxic and ototoxic side effects, however, their widespread clinical usage has typically been limited to the treatment of serious infections. Neomycin B, first isolated from strains of Streptomyces in 1948, is one such drug that was approved for human use by the U. S. Food and Drug Administration in 1964. Only within the last 11 years has the biochemical pathway for its production been elaborated, however...

BACKGROUND: Bacterial contamination of cord blood (CB) represents a safety risk for transplantation patients. CB sterility testing at Canadian Blood Services' Cord Blood Bank is performed using a 1:1 mix of CB-derived plasma and red blood cells (RBCs). Culture bottles of an automated culture system, which lack antimicrobial neutralization properties, are used for bacterial screening of CB. This process is unsuitable for CB-containing antibiotics, potentially resulting in false-negative results...
