OBJECTIVES The aim of this study was to evaluate the dissemination of metallo-beta-lactamase (MBL)-encoding genes among multidrug-resistant (MDR) Pseudomonas aeruginosa isolates recovered from major hospitals in the Hiroshima region. METHODS During July to December from 2004 to 2006, a surveillance of eight major hospitals in the Hiroshima region(More)
OBJECTIVE Invasive Trichosporon infection has been increasingly recognized in patients with hematologic malignancies. Our study aims to clarify the clinical characteristics of this disease and factors influencing patient prognosis. PATIENTS AND METHODS We retrospectively analyzed 33 cases of Trichosporon fungemia (TF) in patients with hematologic(More)
BACKGROUND Invasive oral aspergillosis is a rare complication and only little information on the epidemiology of Aspergillus flavus infection is available. We present here the molecular analysis of the epidemiology of invasive stomatitis due to Aspergillus flavus in patients with acute leukemia. METHODS During a 5-year period (1992-1996), six isolates of(More)
Two actinomycete strains isolated from two patients with lung nocardiosis between 1995 and 1997 in Japan were assigned to novel species of the genus Nocardia based on morphological and chemical criteria. Comparative 16S rRNA gene sequence analysis of the two strains revealed that they belong to the genus Nocardia and are most closely related to the species(More)
Pseudomonas aeruginosa showing resistance to imipenem were found in 100 of 1,058 strains (9.5%) from six hospitals (a-f) in Hiroshima City, Japan. Of the 100 strains, 14 (14%) were double disk synergy test positive using sodium mercaptoacetic acid disks, and 18 (18%) were bla(IMP-1) or bla(VIM-2) allele positive by polymerase chain reaction (PCR). Among 100(More)
The detection of serum 1,3-β-d-glucan (BDG) has been reported to be useful for the diagnosis and therapeutic monitoring of various invasive fungal infections. Although Trichosporon fungemia is increasingly recognized as a fatal mycosis in immunocompromised patients, the utility of this assay for Trichosporon fungemia is still unknown. In our experience (28(More)
