BACKGROUND There are concerns about reduced efficacy of vancomycin in patients with Staphylococcus aureus bacteremia (SAB), especially when the minimum inhibitory concentration (MIC) nears the upper limit of the susceptible range. METHODS We examined the relationship between antibiotic treatment, 30-day mortality, and microbiologic parameters in a large(More)
A ratio of the vancomycin area under the concentration-time curve to the MIC (AUC/MIC) of ≥ 400 has been associated with clinical success when treating Staphylococcus aureus pneumonia, and this target was recommended by recently published vancomycin therapeutic monitoring consensus guidelines for treating all serious S. aureus infections. Here, vancomycin(More)
OBJECTIVES To investigate the incidence and epidemiology of non-multiresistant methicillin-resistant Staphylococcus aureus (nmMRSA) infection in south-east Queensland, Australia. STUDY DESIGN A retrospective survey was done of hospital records of all patients who had non-multiresistant MRSA isolated at Ipswich Hospital (a 250-bed general hospital, 40 km(More)
OBJECTIVE To document the types of, and mortality from, Staphylococcus aureus bacteraemia in Australia and New Zealand, and determine factors associated with mortality. DESIGN AND SETTING Prospective observational study in 27 independent or hospital pathology laboratories in Australia (24) and New Zealand (3), employing a web-based database to(More)
One approach to microbial genotyping is to make use of sets of single-nucleotide polymorphisms (SNPs) in combination with binary markers. Here we report the modification and automation of a SNP-plus-binary-marker-based approach to the genotyping of Staphylococcus aureus and its application to 391 S. aureus isolates from southeast Queensland, Australia. The(More)
Community-acquired methicillin-resistant Staphylococcus aureus (CA-MRSA) infection in children is increasingly common and can be associated with dissemination and life-threatening complications. Empiric therapy for presumed severe Staphylococcus aureus infection should be reviewed. Four children with severe invasive CA-MRSA infection causing osteomyelitis(More)
Community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) infections are emerging in southeast Queensland, Australia, but the incidence of carriage of CA-MRSA strains is unknown. The aim of this study was to assess the nasal carriage rate of S. aureus, including CA-MRSA strains, in the general adult population of southeast Queensland. 396(More)
Non-multiresistant methicillin-resistant Staphylococcus aureus (nmMRSA) infections are emerging worldwide and are often community-associated. This prospective case–cohort study compares features of 96 nmMRSA clinical isolates with 96 matched multiresistant MRSA (mMRSA) and 192 matched methicillin-susceptible S. aureus (MSSA) clinical isolates. Seventy-four(More)
Septic cavernous sinus thrombosis is an uncommon clinical syndrome with a high morbidity and mortality. The commonest bacterial pathogen is Staphylococcus aureus. We describe the study of a patient with cavernous sinus thrombosis and meningitis caused by community-acquired methicillin-resistant S. aureus (CA-MRSA) infection. The isolate was genotyped as the(More)
We performed a meta-analysis of randomised clinical studies in which the efficacy and toxicity of the same total daily dose of aminoglycosides administered once-daily was compared with multiple divided daily dosing for treating human infections. Of twenty-eight publications identified from a literature search using Medline 19 publications of 20 study(More)
