This first vaccine consisted of a combination of three recombinant chlamydial antigens fused to the expression carrier protein, maltose binding protein. Antibiotics are the current treatment for chlamydial infection and disease in koalas, however, they can be detrimental for the koala’s gastrointestinal tract microbiota and in severe cases, can lead to dysbiosis and death. Healthy koalas spend their days in the treetops, but the bacteria and accompanying maladies sap them of the strength they need to climb.

In the PmpG vaccine cohort, 3 koalas (P8, P9 and P11) showed an increase in Chlamydia load post-vaccination (3/21 koalas; 2 ocular sites, 2 UGT sites), corresponding to 3 new infections (Table 3). Conclusions: Koalas vaccinated with a prototype Chlamydia vaccine may live longer than unvaccinated ones. This study demonstrates that the use of a vaccine can have a positive effect in koalas already with clinical signs of ocular disease, suggesting a possible therapeutic effect and an alternative to antibiotic therapy. Treating koalas for chlamydia alters gut microbes. (The government was supposed to complete a koala recovery plan in 2014, but it remains unfinished.)
