Infection by polyomavirus BK (BKV) is an emerging problem in the clinical management of renal transplant patients because it is responsible for nephropathy and consequently can cause loss of the transplanted organ (BKV associated nephropathy, BKVAN). Aim of this study was to evaluate the use of blood viral load measurement as a screening tool for diagnosis(More)
Although in decline after successful anti-HIV therapy, B-cell lymphomas are still elevated in HIV-1-seropositive (HIV+) persons, and the mechanisms are obscure. The HIV-1 matrix protein p17 persists in germinal centers long after HIV-1 drug suppression, and some p17 variants (vp17s) activate Akt signaling and promote growth of transformed B cells. Here we(More)
Of 901 group B streptococcus strains analyzed, 13 (1.4%) were resistant to levofloxacin (MICs of >32 μg/ml for seven isolates, 2 μg/ml for four isolates, and 1.5 μg/ml for four isolates). Mutations in the quinolone resistance-determining regions (QRDRs) of gyrase and topoisomerase IV were identified. A double mutation involving the Ser-81 change to Leu for(More)
BACKGROUND The pandemic influenza A (H1N1) 2009 (H1N1pdm09) virus infection caused illness and death among people worldwide, particularly in hematologic/oncologic patients because influenza infected individuals can shed virus for prolonged periods, thus increasing the chances for the development of drug-resistant strains such as oseltamivir-resistant(More)
Pidotimod (3-L-pyroglutamyl-L-thiaziolidine-4-carboxylic acid) (PDT) is a synthetic dipeptide with in vitro and in vivo immunomodulatory properties that is largely used for treatment and prevention of infections in paediatric and disease-prone patients. However, the effects of PDT on cellular immune responses are still poorly characterized and there is(More)
Carbapenem-resistant K. pneumoniae has recently been reported as a new multidrug-resistant nosocomial pathogen. This study reports the emergence of carbapenem-resistant K. pneumoniae strains in Brescia Civic Hospital, Italy. Different samples, collected from April 2012 to February 2013, showed that 29 patients presented infections from multidrug-resistant(More)
The purpose of this study is to analyze isolates of Clostridium difficile from patients with nosocomial acquired infection in respect to their molecular type and antimicrobial susceptibility. Fifty-nine randomly selected clinical isolates were characterized. Molecular typing was performed by rep-PCR (DiversiLab). Isolates were tested by disk diffusion(More)
