Molecular typing of Klebsiella species has become important for monitoring dissemination of β-lactamase-producers in hospital environments. The present study was designed to evaluate poly-trinucleotide (GTG)(5)- and rDNA intergenic transcribed spacer (ITS)-PCR fingerprint analysis for typing of Klebsiella pneumoniae and Klebsiella oxytoca isolates. Multiple displacement amplified DNA derived fr...

The 5' non-coding region of the genomes of 11 isolates of Murray Valley encephalitis virus from Australia and Papua New Guinea were examined by primer extension sequencing. Although the 5' non-coding region of all isolates was found to be highly conserved, three isolates were significantly different in that they contained extra uridine residues. Two of these isolates from Papua New Guinea conta...

Endovascular infections caused by Staphylococcus aureus involve interactions with fibronectin present as extracellular matrix or surface ligand on host cells. We examined the expression, structure, and binding activity of the two major S. aureus fibronectin-binding proteins (FnBPA, FnBPB) in 10 distinct, methicillin-resistant clinical isolates from patients with either persistent or resolving b...

We report on the isolation of Candida nivariensis from a renal transplant patient with persistent candiduria. Biochemical profiling misidentified isolates as Candida glabrata (3/5) and Candida inconspicua (2/5). All isolates produced white colonies on CHROMagar(™) Candida medium. Internal transcribed spacer (ITS) ribosomal gene sequence analysis and MALDI-TOF-MS analysis (Bruker Biotyper(™) 2.0...

We have determined the nucleotide sequence of the 5'-terminal region of the hepatitis G virus (HGV) genome in 11 hepatitis patients from three cities in China. Phylogenetic analyses revealed that the Chinese isolates were genetically distinct from previously described West African isolates (type 1) and American, European and East African isolates (type 2), with a mean sequence divergence of app...

We investigated the molecular basis of resistance of the obligate biotrophic grape powdery mildew fungus Uncinula necator to sterol demethylation-inhibiting fungicides (DMIs). The sensitivity of 91 single-spore field isolates of U. necator to triadimenol was assessed by using a leaf disc assay. Resistance factors (RF) ranged from 1.8 to 26.0. The gene encoding the target of DMIs (eburicol 14 al...

BACKGROUND AND PURPOSE Surveillance data of colonization by Haemophilus influenzae in Taiwan are lacking. This study aimed to define the nasopharyngeal carriage rate of H. influenzae among children younger than 5 years in northern Taiwan, and to determine the antibiotic susceptibility, serotype and the clonal relationship of these isolates. METHODS Nasopharyngeal specimens were obtained from ...

BACKGROUND Clostridium difficile infection (CDI) is major growing problem in hospitals and its high incidence has been reported in recent years. OBJECTIVES The aim of this study was to investigate the antimicrobial susceptibility patterns of C. difficile clinical isolates against antibiotics commonly used for treatment CDI in hospitalized patients. MATERIAL AND METHODS During a 12 month stu...
