Rapid, accurate discrimination between methicillin-sensitive Staphylococcus aureus (MSSA) and methicillin-resistant S. aureus (MRSA) strains is essential for appropriate therapeutic management and timely intervention for infection control. A rapid method involving intact cell mass spectrometry (ICMS) is presented that shows promise for identification,(More)
Intact cell mass spectrometry (ICMS) rapidly analyses the surface composition of microorganisms providing rapid, discriminatory fingerprints for identification and subtyping of important nosocomial pathogens such as methicillin resistant Staphylocccus aureus (MRSA). In this study, ICMS using matrix-assisted laser desorption ionisation time-of-flight mass(More)
In a comparative study, isolates of methicillin-resistant Staphylococcus aureus (MRSA) with known pulsed-field gel electrophoresis (PFGE) and bacteriophage type were analysed by polymerase chain reaction (PCR) and restriction fragment length polymorphisms (RFLP) for additional discriminatory subtyping information. PFGE was previously performed using(More)
BACKGROUND Noroviruses are a leading cause of gastrointestinal disease and are of particular concern in healthcare settings such as hospitals. As the virus is reported to be environmentally stable, effective decontamination following an outbreak is required to prevent recurrent outbreaks. AIM To investigate the use of hydrogen peroxide vapour to(More)
A range of opportunistic pathogens have been associated with dental unit water systems (DUWS), particularly in the biofilms that can line the tubing. This study therefore aimed to assess the microbiology of DUWS and biofilms in general dental practices across seven European countries, including the United Kingdom (UK), Ireland (IRL), Greece (GR), Spain(More)
A gas chromatographic-mass spectrometric method was used to detect Legionella pneumophila in biofilms in potable water containing a complex microbial consortium. The unique 3-hydroxy and 2,3-dihydroxy fatty acids of the L. pneumophila lipopolysaccharides (LPS) were detected in both the planktonic phase of the continuous culture model and in the biofilms(More)
Pseudomonas aeruginosa is one of many micro-organisms that can act as an opportunistic pathogen and colonize and infect vulnerable patients. Hospital water is a recognized source P. aeruginosa. Several outbreaks, including the incidents involving babies in Northern Ireland in 2011/12, have been attributed to contaminated water systems. As a direct result of(More)
A pilot Integrated Fruit Production (IFP) programme for pest and disease management was evaluated on approximately 88 apple orchards throughout New Zealand. Insect control was based on increased use of biological control, monitoring and threshold-based applications of insecticides. The insect growth regulator tebufenozide was used for control of codling(More)
BACKGROUND Pseudomonas aeruginosa is an opportunistic pathogen with a particular propensity to cause disease in the immunocompromised. Water systems have been reported to contribute to P. aeruginosa transmission in healthcare settings. AIM To systematically assess the evidence that healthcare water systems are associated with P. aeruginosa infection; to(More)
