The International Pseudomonas aeruginosa Consortium is sequencing over 1000 genomes and building an analysis pipeline for the study of Pseudomonas genome evolution, antibiotic resistance and virulence genes. Metadata, including genomic and phenotypic data for each isolate of the collection, are available through the International Pseudomonas Consortium(More)
OBJECTIVES The whole genomes of two Acinetobacter baumannii isolates recovered from a single patient were sequenced to gain insight into the nature and extent of genomic plasticity in this important nosocomial pathogen over the course of a short infection. The first, AB210, was recovered before tigecycline therapy and was susceptible to this agent; the(More)
Genetic robustness, or fragility, is defined as the ability, or lack thereof, of a biological entity to maintain function in the face of mutations. Viruses that replicate via RNA intermediates exhibit high mutation rates, and robustness should be particularly advantageous to them. The capsid (CA) domain of the HIV-1 Gag protein is under strong pressure to(More)
Periodontal disease is the most widespread oral disease in dogs which if left untreated results in significant pain to the pet and loss of dentition. The objective of this study was to identify bacterial species in canine plaque that are significantly associated with health, gingivitis and mild periodontitis (<25% attachment loss). In this survey(More)
Chronic bacterial infections are a key feature of a variety of lung conditions. The opportunistic bacterium, Pseudomonas aeruginosa, is extremely skilled at both colonizing and persisting in the airways of patients with lung damage. It has been suggested that the upper airways (including the paranasal sinuses and nasopharynx) play an important role as a(More)
OBJECTIVES Exploring associations between the gut microbiota and colonic inflammation and assessing sequential changes during exclusive enteral nutrition (EEN) may offer clues into the microbial origins of Crohn's disease (CD). METHODS Fecal samples (n=117) were collected from 23 CD and 21 healthy children. From CD children fecal samples were collected(More)
Two computational biologists give advice when starting out on computational projects. T he term 'computational biologist' can encompass several roles, including data analyst, data curator, database developer, stat-istician, mathematical modeler, bioinforma-tician, software developer, ontologist—and many more. What's clear is that computers are now essential(More)
Variable number tandem repeat (VNTR) analysis at nine loci of isolates of Pseudomonas aeruginosa submitted to the national reference laboratory from UK hospitals, from over 2000 patients, between June 2010 and June 2012 revealed four widely found types that collectively were received from approximately a fifth of patients, including from those with cystic(More)
OBJECTIVES Biocides are widely used to prevent infection. We aimed to determine whether exposure of Salmonella to various biocides could act as a driver of antibiotic resistance. METHODS Salmonella enterica serovar Typhimurium was exposed to four biocides with differing modes of action. Antibiotic-resistant mutants were selected during exposure to all(More)
