BACKGROUND: Bloodstream infections (BSI) represent an important source of morbidity and mortality, as well as an increasing therapeutic challenge, among solid organ transplant recipients. Understanding the epidemiological and microbiological characteristics of BSI following renal transplantation is paramount to the implementation of appropriate preventative and therapeutic measures. METHODS: We conducted a retrospective review of all BSI episodes occurring between July 2009 and April 2016 in adult patients, who received a renal transplant at Royal Free London hospital...

Discovered in swine manure relatively recently, Robsinoniella peoriensis is a gram-positive anaerobic bacilli that has been reported to cause human infections. Its antimicrobial susceptibility, epidemiology and overall pathogenicity are still not fully understood. We report a case of a hardware related soft tissue infection in the right femur caused by Robinsoneilla peoriensis following an open reduction internal fixation in a 67 year old immunocompetent woman. The patient was successfully treated with six weeks of ertapenem...

Carbapenem-resistant Enterobacteriaceae are an urgent threat to global human health. These organisms produce β-lactamases with carbapenemase activity, such as the metallo-β-lactamase NDM-1, which is notable due to its association with mobile genetic elements and the lack of a clinically useful inhibitor. Here we examined the ability of copper to inhibit the activity of NDM-1 and explored the potential of a copper coordination complex as a mechanism to efficiently deliver copper as an adjuvant in clinical therapeutics...

We present an isolate of Klebsiella pneumoniae OXA-48 isolated in a 68-year-old man who underwent radical prostatectomy due to prostate cancer. The antibiotic susceptibility testing to a wide range of antibiotics was performed by disk diffusion method and determination of minimal inhibitory concentrations. The isolate was classified as multidrug-resistant. It showed intermediate susceptibility to imipenem and meropenem, resistance to ertapenem, and sensitivity only to colistin, amikacin, and trimethoprim-sulfamethoxazole...

Limited available data for dosing in obesity of the medicines used in this case are discussed, with the emphasis on ertapenem. The case illustrates the difficulties in dosing medicines to morbidly overweight patients. The number of such patients is increasing but data on adequate doses of medicines are scarce. We demonstrate that ertapenem 1,5 g i.v. once daily provided adequate drug exposure for susceptible bacteria in a 250 kg patient with normal renal function. The case suggests the usefulness of therapeutic drug monitoring of antibiotics, especially in critically ill patients...

Fluoroquinolones (FQ) are potential treatments to treat infections from extended-spectrum β-lactamase producing-Enterobacteriaceae susceptible to FQ. Due to increasing non-susceptibility to carbapenems among Enterobacteriaceae, we characterized FQ resistance mechanisms in 36 Klebsiella pneumoniae isolates that are non-susceptible to ertapenem in North-Eastern France in 2012 and described the population structure by pulsed field gel electrophoresis (PFGE) and multi-locus sequence typing (MLST). Among them, 36% (13/36) carried a carbapenemase encoding-gene...

Background: Broad-spectrum antibiotics are often used to treat urinary tract infections (UTIs) due to drug-resistant species of Enterobacteriaceae and Enterococcus (e.g., organisms producing extended-spectrum β-lactamase [ESBL] or AmpC β-lactamase, as well as vancomycin-resistant enterococci [VRE]). However, this type of therapy can promote selection of resistant organisms and may necessitate venous access. Fosfomycin is an orally administered, single-dose antibiotic for the treatment of uncomplicated UTI...

In most bacteria, the essential targets of β-lactam antibiotics are the D,D-transpeptidases that catalyze the last step of peptidoglycan polymerization by forming 4→3 cross-links. The peptidoglycan of Clostridium difficile is unusual since it mainly contains 3→3 cross-links generated by L,D-transpeptidases. To gain insight into the characteristics of C. difficile peptidoglycan cross-linking enzymes, we have purified the three putative C. difficile L,D-transpeptidases paralogues, LdtCd1, LdtCd2, and LdtCd3, which have been previously identified by sequence analysis...

RELEVANCE: Acute pyelonephritis is known to be the most complicated and severe urinary tract infection occurring in all age groups and accounting for 14% of all kidney diseases. The generally recognized standard antibiotic therapy cannot completely prevent the progression of the disease to its chronic form after relief of its acute manifestations thus leading to a high incidence of relapses. The aim of our study was to investigate the spectrum of uropathogens and their antibiotic sensitivity in acute obstructive pyelonephritis...
