Although Brucella species is known to affect almost all organs in humans, renal involvement presenting as acute pyelonephritis remains a rare entity in brucellosis. We report the case of a female patient who presented with symptoms of fever with chills, right loin pain and dysuria in the emergency room. Blood cultures drawn at the time of admission grew Brucella spp., but no organisms were isolated from urine culture although urinalysis data was indicative of urinary tract infection. Empiric therapy with piperacillin/tazobactam plus gentamicin relieved her symptoms...

The prevalence of fungi in the respiratory tract of cystic fibrosis (CF) patients has risen. However, fungal surveillance is not routinely performed in most clinical centers in the United States, which may lead to an underestimation of the true prevalence of the problem. We conducted a prospective study comparing fungal detection rates for clinically important fungi (CIF) defined as Aspergillus species, Scedosporium species, Trichosporon species, and Exophiala dermatitidis in CF sputum using standard bacterial culture media and selective-fungal culture media, including Sabouraud dextrose agar with gentamicin (SDA), inhibitory mold agar (IMA), and brain-heart infusion agar (BHI) with chloramphenicol and gentamicin...

The Rapid Aminoglycoside NP (Nordmann/Poirel) test was developed to rapidly identify multiple aminoglycoside (AG) resistance in Enterobacteriaceae It is based on the detection of the glucose metabolism related to enterobacterial growth in presence of a defined concentration of amikacin plus gentamicin. Formation of acid metabolites was evidenced by a color change (orange to yellow) of the red phenol pH indicator. The Rapid Aminoglycoside NP test was evaluated by using bacterial colonies of 18 AG-resistant isolates producing 16S rRNA methylases, 20 AG-resistant isolates expressing AG-modifying enzymes (acetyl, adenyl and phospho transferases), and 10 isolates susceptible to AG...

A major factor in the resilience of Listeria monocytogenes is the alternative sigma factor B (σ(B)). Type II Toxin/Antitoxin (TA) systems are also known to have a role in the bacterial stress response upon activation via the ClpP or Lon proteases. Directly upstream of the σ(B) operon in L. monocytogenes is the TA system mazEF, which can cleave mRNA at UACMU sites. In this study, we showed that the mazEF TA locus does not affect the level of persister formation during treatment with antibiotics in lethal doses, but exerts different effects according to the sub-inhibitory stress added...

OBJECTIVES: Published nomograms to monitor extended-interval dosing (EID) gentamicin therapy were based on a fixed dose of 5 or 7 mg/kg. However, the average dose used for EID gentamicin regimen in our setting was about 3 mg/kg per day. We developed a new method of monitoring based on the duration of drug-free period (DFP) in a 24-h dosing interval. METHODS: Hospitalised adult patients on EID gentamicin were selected. We considered a DFP of between 2 and 8 h as appropriate...

♦ Background: Peritonitis is a major cause of morbidity, mortality, and technique failure in peritoneal dialysis (PD) patients, especially when caused by enteric microorganisms (EM). We have implemented a treatment protocol specifically aimed at improving the outcome in EM peritonitis. The adapted protocol was applied in all PD patients 50 years and older presenting with peritonitis who were considered to be at risk of EM peritonitis and involves 3 interventions: 1) temporary discontinuation of PD without removing the catheter (peritoneal rest), 2) intravenous meropenem, and 3) meropenem intracatheter as lock (Mero-PerRest protocol)...

Commonly used antimicrobials show poor cellular uptake and often have limited access to intracellular targets, resulting in low antimicrobial activity against intracellular pathogens. An efficient delivery system to transport these drugs to the intracellular site of action is needed. Cell-penetrating peptides (CPPs) mediate the internalization of biologically active molecules into the cytoplasm. Here we characterized two CPPs, α1H and α2H, derived from the Y. enterocolitica YopM effector protein. These CPPs, as well as Tat(Trans-activator of transcription) from HIV-1 virus, were used to deliver the antibiotic gentamicin to target intracellular bacteria...

REVIEW
Volker Alt
Implant-associated infections remain a major issue in orthopaedics and antimicrobial functionalization of the implant surface by antibiotics or other anti-infective agents have gained interest. The goal of this article is to identify antimicrobial coatings, for which clinical data are available and to review their clinical need, safety profile, and their efficacy to reduce infection rates. PubMed database of the National Library of Medicine was searched for clinical studies on antimicrobial coated implants for internal fracture fixation devices and endoprostheses for bone surgery, for which study design, level of evidence, biocompatibility, development of resistance, and effectiveness to reduce infection rates were analyzed...

Although single-drug therapy may prove insufficient in treating bacterial infections or inflammation after orthopaedic surgeries, complex therapy (using both an antibiotic and an anti-inflammatory drug) is thought to address the problem. Among drug delivery systems (DDSs) with prolonged drug release profiles, nanoporous anodic titanium dioxide (ATO) layers on Ti foil are very promising. In the discussed research, ATO samples were synthesized via a three-step anodization process in an ethylene glycol-based electrolyte with fluoride ions...

Klebsiella pneumoniae is a bacterium that can be in relation with free living amoebae like Acanthamoeba castellanii in natural environments such as soil and water. This pathogen, which is responsible for community-acquired pneumonia and for nosocomial infections, also has interactions with host defense mechanisms like macrophages. As it has been shown that A. castellanii shares some traits with macrophages, in particular the ability to phagocyte bacteria, we have studied the uptake and the fate of the bacteria after contact with the two phagocytic cells...
