High stringency evaluation of the inactivation / exclusion efficacy of a MALDI-TOF MS chemical extraction method, with filtration of extract through 0.1 µm filters, on Bacillus anthracis Vollum vegetative cells and spores.

A previous report indicated that a formic acid chemical extraction method for the preparation of protein extracts for matrix-assisted laser desorption time-of-flight mass spectrometry (MALDI-TOF MS) identification, with filtration of extracts through 0.2 μm regenerated cellulose (RC) filters, would not reliably inactivate or exclude Bacillus anthracis Vollum cells or spores when tested under high stringency conditions.

Novel genotypes of Coxiella burnetii identified in isolates from Australian Q fever patients.

Coxiella burnetii, the causative agent of Q fever, was first discovered in Australia in 1937. However, little is known about the strains of C. burnetii present in this country.

Whole Genome Analysis of Injectional Anthrax Identifies Two Disease Clusters Spanning More Than 13 Years.

Background: Anthrax is a rare disease in humans but elicits great public fear because of its past use as an agent of bioterrorism. Injectional anthrax has been occurring sporadically for more than ten years in heroin consumers across multiple European countries and this outbreak has been difficult to trace back to a source.

Methods: We took a molecular epidemiological approach in understanding this disease outbreak, including whole genome sequencing of Bacillus anthracis isolates from the anthrax victims.

Whole-genome sequencing investigation of animal-skin-drum-associated UK anthrax cases reveals evidence of mixed populations and relatedness to a US case.

There have been two anthrax cases affecting people that played and/or made animal-skin drums in the UK during the last 10 years, with single fatal occurrences in Scotland in 2006 and London in 2008. Investigations by the Health Protection Agency (now Public Health England) employing multi-locus-variable number tandem repeat analysis had previously linked the clinical cases to spores associated with animal skins and drums the patients had been in contact with. In this study, whole-genome sequencing of 23 isolates harvested during the investigations was performed.

A non-fatal case of hantavirus cardiopulmonary syndrome imported into the UK (ex Panama), July 2014.

• Detection of hantavirus cardiopulmonary syndrome imported into Europe. • Additional evidence that is currently circulating and causing human disease in Panama. • Novel diagnostic and sequencing assays for identifying cases of infection.

Genome Sequence of Ex-Afghanistan Crimean-Congo Hemorrhagic Fever Virus SCT Strain, from an Imported United Kingdom Case in October 2012.

Crimean-Congo hemorrhagic fever (CCHF) virus is a serious human pathogen causing severe hemorrhagic disease with a fatality rate of up to approximately 30%. We have determined the viral genomic sequence from an isolate that caused a fatal case of imported CCHF in the United Kingdom in October 2012.

Molecular epidemiologic investigation of an anthrax outbreak among heroin users, Europe.

In December 2009, two unusual cases of anthrax were diagnosed in heroin users in Scotland. A subsequent anthrax outbreak in heroin users emerged throughout Scotland and expanded into England and Germany, sparking concern of nefarious introduction of anthrax spores into the heroin supply. To better understand the outbreak origin, we used established genetic signatures that provided insights about strain origin.
