Imported biological products are ubiquitous necessities of modern life that can pose significant biosecurity risks to Australia. Products produced using animal material are used everywhere from enzymes in cleaning products, to cell lines and bacterial cultures used to produce vaccines and medicines. This article highlights adventitious agents of biologicals and provides an overview of the considerations

The rapid testing for Security Sensitive Biological Agents is carried out by Public Health laboratories. The commercial platforms for performing such tasks in Australia are described.

Biosecurity is a term broadly applied to the protection, control and accountability of biological agents and toxins to minimise the risk of their introduction through natural, unintentional (accidents) or deliberate processes. Biosecurity protection involves the engagement of all stakeholders including government, public health networks, industry, and scientific community. While the Commonwealth Government

As Australia’s national law enforcement agency the Australia Federal Police (AFP) plays a number of roles, broadly grouped under intelligence and investigation, in supporting a whole of government approach to responding to, and mitigating, risks from Security Sensitive Biological Agents (SSBA). The AFP is responsible for coordinating the investigation of national and transnational crimes, which includes

The novel betacoronavirus, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has caused a global pandemic unprecedented in modern times. Understanding the key features that have enabled this virus to propagate so widely in the global community is critical to current and future clinical and public health efforts. High proportions of mild disease and peak viral loads at, and likely prior

Bioterrorism is the deliberate misuse of a pathogen (virus, bacterium or other disease-causing microorganisms) or biotoxin (poisonous substance produced by an organism) to cause illness and death amongst the population. Bioterrorism and biological warfare (biowarfare) are terms often used interchangeably. However, bioterrorism is typically attributed to the politically motivated use of biological weapons

Exotic and emerging infectious diseases are emerging more frequently, and impacting more profoundly, all of humanity. Disasters risk reduction efforts over the preceding decades, culminating in the Hyogo and Sendai frameworks, have provided a roadmap for all countries to address emerging disaster related risks. Sudden onset or surprise epidemics of exotic or emerging diseases have the potential to

The aim of Australia’s Security Sensitive Biological Agents (SSBAs) Regulatory Scheme is to limit opportunities for acts of bioterrorism or criminal acts using harmful biological agents. The scheme is based on a two-tiered list of agents, of which many can cause disease in animals and thereby have the potential to significantly impact Australian agricultural industries and the economy. Laboratories

The Royal College of Pathologists (RCPA) and then RCPA Quality Assurance Programs Pty Ltd (RCPAQAP), a company independent from but aligned with the RCPA, have been producing proficiency testing programs (PTP) for infectious diseases for 52 years. This involves sending infectious disease material in surveys to over 80 countries worldwide throughout any year. The PTP panels are developed depending on

I will begin this Vertical Transmission by hoping that you and your families are all healthy and well, and coping during this very confused and frightening time. Microbiology and public health are certainly at the forefront of community and government attention at this time, and rapid solutions are being sought to deal with the SARS-CoV-2 pandemic. Unfortunately, funding for discovery research that

This issue of Microbiology Australia is on the topic of probiotics. The word ‘probiotic’ meaning ‘for life’ is derived from Latin ‘pro’ and Greek ‘bios’. According to the World Health Organization and the Food and Agriculture Organization of the United Nations, probiotics are defined as ‘live microorganisms which when administered in adequate amounts confer a health benefit on the host’1, while a very

The SARS-Cov2 has presented the world with a novel pandemic challenge requiring a rapid response. This article provides a May 2020 snapshot from Professor Paul Young, who is part of a group working with urgency on Australia’s leading COVID-19 candidate vaccine.

There is growing interest in the use of probiotics in neonates. In particular, Lactobacillus rhamnosus, L. acidophilus, Bifidobacterium breve and B. longum have been well studied. Caesarean-section (CS)-born infants often lack Lactobacillus spp. and Bifidobacterium spp., which showed increasing evidence in establishing the neonatal immune system. Furthermore, CS increases the difficulties for mothers

Faecal microbiota transplantation (FMT) is the transfer of human faeces from a healthy donor to a recipient with a disease associated with gut dysbiosis. Here we review faecal microbiota transplantation as a treatment for Clostridioides difficile infection (CDI) and other conditions including decolonisation of multiresistant organisms. Donor selection and screening, adverse events, processing, administration

The gut microbiome is made up of hundreds of trillions of microorganisms that reside in a state of homeostatic balance within the healthy individual. Next generation sequencing has provided insight into the diversity of these microorganisms that reside within our gastrointestinal tract; despite developments in metabolomics and culturing techniques, the functions of many of these bacteria remain largely

The concept of probiotics is well known and has developed into a high value commodity in recent times. Despite the ever-expanding number of probiotic products on our pharmacy, health food and supermarket shelves, the probiotic culture active ingredient has always been imported until now. In 2019, Probiotics Australia Pty Ltd opened Australia’s first and only Therapeutic Goods Administration/current

Coral reefs are found in warm, oligotrophic, euphotic marine waters and occupy <0.1% of the sea floor, yet support ~25% of earth’s marine species. They provide critical ecosystem services to human populations including coastal protection, food (e.g. fish) and personal income by way of fishing and tourism. However, recent pan-tropical coral ‘bleaching’ (the paling of corals due to the separation of

Staphylococcus aureus (S. aureus) is a Gram-positive bacterium. When pathogenic S. aureus colonises onto a skin wound or diabetic ulcer, it can cause a serious infection and lead to amputation or death. The current solutions (e.g. antibiotics and probiotics) are not sufficient enough to be a cure for this infection. To worsen the situation, the S. aureus bacteria continue to develop greater resistance

Probiotics are genetically identifiable, live microorganisms that when administered in adequate amounts, confer appropriately sized health benefit (e.g. correcting dysbiosis, immunomodulatory effect) on a target host. In cattle, probiotics have shown promising results and long-term benefits in productivity when used on animals under stress. The health and production benefits of probiotics were attributed

Piglet mortality is a major issue for the pork industry globally and until recently, the main method for improving growth performance and reducing disease in commercial practice is centred on anti-microbial use. Antibiotic resistance is a global concern and, as such, animal production industries are seeking alternatives to antibiotics. Different approaches under investigation include but are not limited

As agriculture and food security face unprecedented challenges, emerging agricultural innovations and existing practices require ongoing examination in the context of sustainability. In this review, we focus on the use of probiotic microorganisms for improved plant production. As plants are enormously diverse, emphasis is placed on the fundamental sites of plant-microbe interactions regarding benefits

Probiotic products are viewed as an alternative to the use of antibiotics in freshwater fishes farming. Probiotic organisms include bacteria, yeast, and filamentous fungi offering different benefits to fish including growth promotion, inhibition of pathogen colonisation, and improvement of nutrient digestion, water quality, and stress tolerance, as well as enhancement of reproduction. For these reasons

Foods containing edible probiotic bacteria, most commonly Lactobacillus and Bifidobacterium species, form a multi-billion-dollar industry worldwide. Currently marketed foods containing probiotics are mostly dairy based with yoghurts and fermented milks dominating the industry. Alternative foods as carriers of probiotics are being examined to reduce or eliminate lactose intolerance issues. Food categories

As we begin 2020, Microbiology is dominating the news with the emergence and rapid dissemination of the novel coronavirus COVID-19. The impact of COVID-19 on public health, with significant financial, logistical and social repercussions, has quickly become apparent. As microbiologists we have an important role to play during this time because we can use our knowledge, expertise and experience to educate

The selection of papers included in this issue of Microbiology Australia present a broad brush of zoonotic diseases, from those known or described in ancient times such as rabies, first described in the Eshnunna cuneiform law tablets from ancient Mesopotamia dating back to the 18th–19th centuries BC, and glanders, thought to be first described in donkeys by Aristotle in Ancient Greece in 420–450 BC

Leila Valerie James was born at Rupanyup in western Victoria in 1927. She attended local schools and continued her education despite significant family hardship. After matriculating from Ballarat High School she achieved her dream of going to The University of Melbourne and in 1944 commenced her BSc while living in nearby Brunswick. At Easter she fell ill with pleurisy. After a local GP drained 3 pints

At the end of December, 2019, a new disease of unknown aetiology appeared in Wuhan, China. It was quickly identified as a novel betacoronavirus, and related to SARS-CoV and a number of other bat-borne SARS-like coronaviruses. The virus rapidly spread to all provinces in China, as well as a number of countries overseas, and was declared a Public Health Emergency of International Concern by the Director-General

Rift Valley fever (RVF) is a mosquito-borne viral disease, principally of ruminants, that is endemic to Africa. The causative Phlebovirus, Rift Valley fever virus (RVFV), has a broad host range and, as such, also infects humans to cause primarily a self-limiting febrile illness. A small number of human cases will also develop severe complications, including haemorrhagic fever, encephalitis and visual

Seafood is an increasingly popular source of healthy protein. Since 1961, the average annual increase in global food fish consumption has been twice as high as population growth and exceeds the consumption of meat from all terrestrial animals combined1. The following overview of seafood safety concerns is intended to help readers to understand potential risks associated with parasites in seafood products

Glanders, although known to be endemic in certain regions/countries of the Old and New Worlds for centuries, had been largely overlooked as a threat to equine and human health until the disease re-emerged in the Middle East in 2004. The exponential growth in international horse movements, both legal and illegal, mainly for performance purposes, has enhanced the risk of global spread of glanders in

It is unacceptable that as we advance into the 21st century rabies is still a threat to humans and animals alike. Given public health interventions that focus solely on disease prevention in humans have no effect on the reduction of infection in the reservoir hosts, the most effective way to combat human rabies infection is to control the disease transmission by mass vaccination of the animal source
