Intersection of CBRN, military forensic science, and counterterrorism.

The wars in Iraq and Afghanistan required that forensic science was used beyond the traditional law enforcement and criminal justice goals and applied to military operations. The 9/11 terror attacks in the United States (US) inspired further attacks in the Western World and highlighted the importance of national and international intelligence sharing for counterterrorism operations. Following the 9/11 attacks, anthrax was disseminated in the US mail system, demonstrating a successful modern use of biological agents.

Kafka's beautiful eyes: Forensic intelligence utilisation of phenotypic information.

Franz Kafka had beautiful eyes. So striking, that many of the famous author's friends and peers commented on them - but quite variously ('dark', 'brown', 'grey' & 'blue'). Eye colour as perceived by an observer is subjective, being influenced by physiological, environmental, and even sociocultural factors.

The secret hidden in dust: Assessing the potential to use biological and chemical properties of the airborne fraction of soil for provenance assignment and forensic casework.

The airborne fraction of soil (dust) is both ubiquitous in nature and contains localised biological and chemical signatures, making it a potential medium for forensic intelligence. Metabarcoding of dust can yield biological communities unique to the site of interest, similarly, geochemical analyses can uncover elements and minerals within dust that can be matched to a geographic location. Combining these analyses presents multiple lines of evidence as to the origin of dust collected from items of interest.

The utility of dust for forensic intelligence: Exploring collection methods and detection limits for environmental DNA, elemental and mineralogical analyses of dust samples.

Environmental DNA (eDNA), elemental and mineralogical analyses of soil have been shown to be specific to their source material, prompting consideration of using the airborne fraction of soil (dust) for forensic intelligence work. Dust is ubiquitous in the environment and is easily transferred to items belonging to a person of interest, making dust analysis an ideal tool in forensic casework. The advent of Massive Parallel Sequencing technologies means metabarcoding of eDNA can uncover bacterial, fungal, and even plant genetic fingerprints in dust particles.

Evaluation of commercial forensic DNA extraction kits for decontamination and extraction of DNA from biological samples contaminated with radionuclides.

In preparing to respond to security incidents involving radioactive material, States should consider how they might address the unique challenge of analysing forensic evidence contaminated with these materials. In the case of DNA evidence, previous research has suggested that commercial forensic DNA extraction kits may be able to remove radioactive contamination from biological samples. If viable, this would allow the extraction and decontamination of biological samples to be undertaken in a laboratory equipped to handle radioactive material, with the subsequent quantification and profiling of extracted DNA performed in a conventional forensics laboratory.

Comparison between magnetic bead and qPCR library normalisation methods for forensic MPS genotyping.

Massively parallel sequencing (MPS) is fast approaching operational use in forensic science, with the capability to analyse hundreds of DNA identity and DNA intelligence markers in multiple samples simultaneously. The ForenSeq™ DNA Signature Kit on MiSeq FGx™ (Illumina) workflow can provide profiles for autosomal short tandem repeats (STRs), X chromosome and Y chromosome STRs, identity single nucleotide polymorphisms (SNPs), biogeographical ancestry SNPs and phenotype (eye and hair colour) SNPs from a sample. The library preparation procedure involves a series of steps including target amplification, library purification and library normalisation.

Characterization of Yersinia species by protein profiling using automated microfluidic capillary electrophoresis.

Yersinia pestis is a biological agent of high risk to national security due to its ability to be easily disseminated and transmitted among humans. If Y. pestis was to be utilized in a deliberate disease outbreak it would be essential to rapidly and accurately identify the agent.

Background frequency of Bacillus species at the Canberra Airport: A 12 month study.

Anthrax, caused by Bacillus anthracis, is a naturally occurring disease in Australia. Whilst mainly limited to livestock in grazing regions of Victoria and New South Wales, movement of people, stock and vehicles means B. anthracis could be present outside this region.

Characterization of Bacillus strains and hoax agents by protein profiling using automated microfluidic capillary electrophoresis.

Purpose: In recent times, but especially since 2001, bioterrorism has been of increasing concern. In addition to the use of biological agents, including Bacillus anthracis (anthrax), there have been numerous hoax white powder "scares." It is imperative to rapidly and accurately identify any suspicious powder as hazardous or hoax.

Recovery and identification of bacterial DNA from illicit drugs.

Bacterial infections, including Bacillus anthracis (anthrax), are a common risk associated with illicit drug use, particularly among injecting drug users. There is, therefore, an urgent need to survey illicit drugs used for injection for the presence of bacteria and provide valuable information to health and forensic authorities. The objectives of this study were to develop a method for the extraction of bacterial DNA from illicit drugs and conduct a metagenomic survey of heroin and methamphetamine seized in the Australian Capital Territory during 2002-2011 for the presence of pathogens.

Diagnosis of Queensland tick typhus and African tick bite fever by PCR of lesion swabs.

We report 3 cases of Queensland tick typhus (QTT) and 1 case of African tick bite fever in which the causative rickettsiae were detected by PCR of eschar and skin lesions in all cases. An oral mucosal lesion in 1 QTT case was also positive.

Diagnosing Smith-Magenis syndrome and duplication 17p11.2 syndrome by RAI1 gene copy number variation using quantitative real-time PCR.

Smith-Magenis syndrome (SMS) and duplication 17p11.2 (dup17p11.2) syndrome are multiple congenital anomalies/mental retardation disorders resulting from either a deletion or duplication of the 17p11.

The detection of Chlamydia pneumoniae in atherosclerotic plaques of Australian subjects.

Aim: To determine whether the common respiratory pathogen, Chlamydia pneumoniae, was associated with atherosclerotic plaques in Australian subjects.

Methods: A total of 29 coronary atherosclerotic lesions and 18 normal coronary arterial samples were tested for the presence of C. pneumoniae by PCR and immunofluorescence methods.
