pharmacy banners. September 2019 was a record-breaking month for Australian revenue, with sales before rebates growing to $185K*

AUD. This is the highest monthly revenue figure on record in one market, exceeding the $182K* AUD record milestone that the USA

over 500 General Practitioners.

"The sales momentum for Travelan

which was already evident in fiscal year 2019 has continued strongly into the first quarter of fiscal year 2020 as consumer awareness

of Travelan continues to grow," said Dr. Gary S. Jacob, CEO of Immuron Ltd. "During the quarter we also made two

ground-breaking announcements regarding our research collaboration with the US Department of Defense. This included the results

from a US DoD study that showed Travelan was cross-reactive against 71 clinical isolates of Vibrio cholera. In addition,

we recently announced a $5.5M AUD grant with the Naval Medical Research Center to develop a combined Campylobacter and enterotoxigenic

E. coli (ETEC)-specific anti-microbial preventative for clinical evaluation."

Infectious diarrhea is the most common

illness reported by travelers visiting developing countries and among US troops deployed overseas. Diarrhea morbidity decreases

daily performance, affects judgment, decreases morale and declines operational readiness. First line treatment for infectious diarrhea

has typically been the prescription of antibiotics. Unfortunately, in the last decade, several enteric pathogens have shown an

increased resistance to commonly prescribed antibiotics. In addition, travelers' diarrhea is now recognized by the medical community

to result in post-infectious sequelae, including post-infectious irritable bowel syndrome and several post-infectious autoimmune

global burden of diarrheal diseases outweighs any of the more complex diseases seen in gastroenterology clinics. Every year, there

are an estimated 1.5 billion episodes of diarrhea worldwide. These episodes result in the deaths of approximately 2.2 million people,

mostly children in developing countries (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2699001/). A preventative treatment

that protects against enteric diseases, specifically shigellosis, is a high priority objective for the US Army. Shigella

spp are estimated to cause 80 -165 million cases of disease worldwide, resulting in 600,000 deaths annually and is particularly

prevalent in both sub-Saharan Africa and South Asia.

About Travelers' Diarrhea

diarrhea is a gastrointestinal infection with symptoms that include loose, watery (and occasionally bloody) stools, abdominal cramping,

bloating, and fever, Enteropathogenic bacteria are responsible for most cases, with enterotoxigenic Escherichia coli (ETEC)

playing a dominant causative role. Campylobacter spp. are also responsible for a significant proportion of cases. The more serious

infections with Salmonella spp., the bacillary dysentery organisms belonging to Shigella spp. and Vibrio spp. (the causative agent

of cholera) are often confused with travelers' diarrhea as they may be contracted while travelling and initial symptoms are

often indistinguishable.
