Koalas get Chlamydia too!
WE NEED A NEW TREATMENT FOR CHLAMYDIA

KOALA DRUGS ARE TRICKY!
Gut microbiome essential Extreme hepatic metabolism Delivery and Efficacy tricky

Not toxic against Koala cells Works on Koala Chlamydia isolates grown in Koala cells
JO146 OR DERIVATIVES AS A KOALA THERAPY???
Yes 3-5 year plan or faster

Summary : Drug development for the Koala Chlamydial diseases
A national icon under major threat
An urgent priority
A challenging scenario for drug discovery
Core capabilities for research:
Chlamydia culture
Biochemistry
Toxicity
Primary Koala tissue work
