Australian Health Journal spoke to Associate Professor Sam Forster, Research Group Head, Microbiota and Systems Biology, Hudson Institute of Medical Research, Team Leader, Australian Microbiome Culture Collection & Chief Scientific Officer, BiomeBank and Dr Sam Costello, Co-Founder and CEO of BiomeBank about the microbiome, partnering and some of the breakthroughs in recent years.
Assoc Prof Forster describes the role of the microbiome, “Every one of us carries thousands of bacteria. Millions of individual cells, and they’re intimately associated with all sorts of sites on our bodies. So our gut is the most common place we think about, but our lungs, our skin, everywhere. Where there’s an interface, the external environment, there’s bacteria and other microbes that actually enable us to interface with the external world. They detect changes and they regulate our immune response.”
This can be really important from a health perspective because they indicate when things are going well, we should have a healthy state or something’s gone wrong, and there is an inflammatory response. This can then be detrimental, or it can help clear a particular condition.
“The microbes we carry are intimately associated with our health.”, says Assoc Prof Forster. He was the founder of the Australian Microbiome Culture Collection at Hudson that now contains over 40,000 bacterial isolates. This provides a resource for further research.
“All of these opportunities are available because we have this vast collection of microbes where we can say this particular combination for you is relevant for this experiment. Taking clinical samples, we then can replicate the host environment using microfluidic organ on-a-chip systems”, says Assoc Prof Forster.
Microbiome therapies involve modifying the body’s microbial communities to improve health. These treatments aim to restore balance to the microbiome, potentially alleviating conditions like inflammatory bowel disease, liver disorders, autoimmune diseases, and certain cancers.
The Hudson Institute of Medical Research and BiomeBank have partnered to advance microbiome-based therapeutics. Their collaboration focuses on identifying key bacteria involved in disease onset and resolution, particularly associated with the gut. By combining their expertise, they aim to develop targeted microbial therapies to treat and prevent diseases by restoring gut microbial ecology.
BiomeBank develops and delivers microbiome therapies. In 2022 BiomeBank was successful in introducing the world’s first approved donor derived microbiome therapy approved in Australia for the treatment of C. Difficile infection.
Through this collaboration, the Hudson Institute and BiomeBank are at the forefront of microbiome research, striving to translate scientific discoveries into effective therapies that can improve patient outcomes.
As Dr Costello states, “We see microbiome therapies evolving in the next few years from predominantly donor derived therapies that are harvested from screened healthy stool donors, towards cultured therapies that can be grown in bioreactors and produced under controlled conditions.”
Assoc Prof Forster has been involved in a number of breakthroughs in culturing previously thought to be unculturable organisms.

Child Dental Benefits Schedule needing greater awareness
Since its launch in 2014, the Child Dental Benefits Schedule has seen a gradual increase in participation year on year. The impact of COVID-19 and related shutdowns saw participation fall sharply in 2020. Though it increased 2021, the national target of 41% participation was not reached in 2021-2022, with the total (35.4%) more than three percent below 2018 participation rates.
In an opinion segment, Australian Health Journal spoke with Abano Healthcare Group Clinical Director, Dr Fred Calavassy, with over 30 years of clinical experience, about his observations of the Child Dental Benefits Scheme ways to increasing participation rates.

Medicinal cannabis in Australia Update
According to the Australian Journal of General Practice, published by the Royal Australian College of General Practitioners, more than 130,000 medicinal cannabis approvals have been issued in Australia to date, mostly by general practitioners, with approximately 65% of these to treat chronic non-cancer pain. Despite robust supportive data from animal models, current clinical trial evidence for THC and CBD efficacy in chronic pain is incomplete. In their prescribing decisions, doctors must balance patient demand and curiosity with caution regarding potential risks and limited efficacy (Source: https://www1.racgp.org.au/ajgp/2021/october/medicinal-cannabis)
Australian Health Journal met with 3 speakers at the recent @arcsaustralia ARCS22 Conference providing an update on medicinal cannabis. The discussion with the speakers now centres on affordability and access.

The Case for Embedded Pharmacy in Residential Aged Care
Embedded pharmacy in residential aged care has been successful in South Australia at the Tanunda Lutheran Home in the Barossa Valley. Julian Soriano talks about his pharmacy role in medication management and medication safety to deliver the best clinical care for residents.
In this segment, Julian talks about the traditional pharmacy model serving residential aged care and the limitations of the imprest process for dispensing medication. Soon into the project he saw the collaboration required with GPs and onsite nurses in dispensing medication for residents in end-of-life or palliative care. Julian sees the imprest process unable to support end-of-life residents, even being able to check the availability of medication.
But what most may not be aware of, is his rapid growth since starting the business in 2013 having just been in health care a few years earlier. Being part of a 2nd generation health care family, Shawn learnt from his father on site and at trade show visits overseas. Prior to HPA, he spent 2 years working in fit-outs of operating theatres, neo-natal and general population ICU, throughout being more fascinated with what he saw.
