The notification of "Gram-positive cocci, possibly staphylococcus" in a blood culture drawn from a seriously ill patient is responsible for a large amount of vancomycin prescribing in institutions where methicillin-resistant Staphylococcus aureus (MRSA) is an important cause of bacteraemia. A duplex real-time TaqMan polymerase chain reaction targeting the(More)
BACKGROUND Antibiotic homogeneity is thought to drive resistance but in vivo data are lacking. In this study, we determined the impact of antibiotic homogeneity per se, and of cefepime versus antipseudomonal penicillin/β-lactamase inhibitor combinations (APP-β), on the likelihood of infection or colonisation with antibiotic resistant bacteria and/or two(More)
We describe the success of adjunctive bacteriophage therapy for refractory Pseudomonas aeruginosa urinary tract infection in the context of bilateral ureteric stents and bladder ulceration, after repeated failure of antibiotics alone. No bacteriophage-resistant bacteria arose, and the kinetics of bacteriophage and bacteria in urine suggest self-sustaining(More)
blaNDM genes, encoding metallo-β-lactamases providing resistance to carbapenems, have been reported in many locations since the initial report in 2008, including in several Enterobacteriaceae isolates in Australia/New Zealand. Here, we compare 4 additional carbapenem-resistant Klebsiella pneumoniae carrying blaNDM-1 isolated in Australia. Two are sequence(More)
Complete sequencing of pEl1573, a representative IncL/M plasmid carrying bla(IMP-4) from Sydney, Australia, revealed an ∼60-kb backbone almost identical to those of IncL/M plasmids pCTX-M3, from Poland, and pCTX-M360, from China, and less closely related to pNDM-HK, pOXA-48a, and pEL60, suggesting different lineages. The ∼28-kb Tn2-derived multiresistance(More)
We describe a conjugative plasmid appearing in a bacteremic clone of Escherichia coli immediately upon exposure to the antibiotics for which it encoded resistance. Effective antibiotic choice was made possible by prior screening for this plasmid. Surveillance for transmissible resistance plasmids may be clinically important.
An assay to detect Strongyloides stercoralis in stool specimens was developed using the loop-mediated isothermal amplification (LAMP) method. Primers were based on the 28S ribosomal subunit gene. The reaction conditions were optimized and SYTO-82 fluorescent dye was used to allow real-time and visual detection of the product. The product identity was(More)
BACKGROUND Many questions remain concerning the burden, risk factors and impact of bacterial and viral co-infection in patients with pandemic influenza admitted to the intensive care unit (ICU). OBJECTIVES To examine the burden, risk factors and impact of bacterial and viral co-infection in Australian patients with severe influenza. PATIENTS/METHODS A(More)
OBJECTIVES Bartonella henselae is a fastidious slow growing pathogen which is seldom cultured in the laboratory. Previous descriptions of antimicrobial susceptibility have been largely limited to feline isolates and/or laboratory reference strains, with no accounting for genotypic or phenotypic diversity. METHODS An optimal method of antimicrobial(More)
blaKPC genes encoding resistance to carbapenems are increasingly widely reported and are now endemic in parts of several countries, but only one Klebsiella pneumoniae isolate carrying blaKPC-2 had previously been reported in Australia, in 2010. Here we characterised this isolate, six additional K. pneumoniae and one Escherichia coli carrying blaKPC and(More)
