Two carbapenem-resistant Raoultella planticola clinical isolates were isolated from patients with pneumonia and Port-A catheter-related bacteremia, respectively, in Taiwan. These isolates remained susceptible to fluoroquinolone, aminoglycoside, and colistin. Though the two isolates had the same antibiogram, plasmidic carbapenemase blaIMP-8, class 1 integron(More)
To investigate the efficacy of fosfomycin against extended-spectrum β-lactamases (ESBL) producing Escherichia coli in Taiwan and the resistance mechanisms and characterization of human and pig isolates, we analyzed 145 ESBL-producing isolates collected from two hospitals (n = 123) and five farms (n = 22) in Taiwan from February to May, 2013. Antimicrobial(More)
A total of 71 fusidic acid-resistant Staphylococcus aureus (45 methicillin-resistant and 26 methicillin-susceptible) isolates were examined for the presence of resistance determinants. Among 45 fusidic acid-resistant methicillin-resistant S. aureus (MRSA), isolates, 38 (84%) had fusA mutations conferring high-level resistance to fusidic acid (the MIC was(More)
We evaluated the disk susceptibility data of 671 nontyphoid Salmonella isolates collected from different parts of Taiwan from March 2001 to August 2001 and 1,261 nontyphoid Salmonella isolates from the National Taiwan University Hospital from 1996 to 2001. Overall, ciprofloxacin resistance was found in 2.7% (18/671) of all nontyphoid Salmonella isolates, in(More)
Nucleotide sequencing of the fusB-flanking regions in two fusidic acid-resistant Staphylococcus epidermidis isolates with the type IV aj1-leader peptide (LP)-fusB structure (lacking aj1) revealed that their fusB gene was located on novel phage-related islands inserted downstream of smpB and are here referred to as SeRIfusB-3692 and SePIfusB-857. The novel(More)
Due to the limited information of the contribution of various antibiotic resistance mechanisms in clinical Burkholderia cepacia complex isolates, Antibiotic resistance mechanisms, including integron analysis, identification of quinolone resistance-determining region mutations, measurement of efflux pump activity, and sequence analysis of efflux pump(More)
We describe the structure of a transposon-like element named Tn6001, which contains a bla(VIM-3)-harboring integron In450, which was derived from a multidrug-resistant Pseudomonas aeruginosa clinical isolate in Taiwan. The transposon backbone structure is most closely related to those of Tn1404* and Tn1403. Tn6001 was inserted into the chromosome of the(More)
Dear Editor, The World Health Organization (WHO) has recently raised a warning that many countries have dengue epidemics or outbreaks. Major dengue fever (DF) cases were reported in Southeast Asia.1 DF is a vector-borne disease caused by dengue virus that belongs to the genus Flavivirus in the family Flaviviridae. Dengue viruses are geographically(More)
