After last week’s news that koalas with chlamydia might help us develop a chlamydia vaccine for humans, we started digging into more animal health research that’s helping humans, too.
Chlamydia is bad. One of the most common sexually transmitted infections, chlamydia can cause scarring and inflammation that leads to “infertility, ectopic pregnancy, or pelvic inflammatory disease,” as well as male infertility and birth abnormalities, explains The New York Times.
It affects koalas, too—causing severe pain and inflammation, cysts, and scarring of the reproductive tract.
Scientists have made progress on a vaccine—for koalas. Trials in Australia show it’s safe and triggers a lifetime immune response in the animals.
This research could help us discover a vaccine for humans, too. “The koala represents a perfect clinical model, because it’s an animal for which you can do some experimentation that’s a little more than what you can do in humans,” said immunologist Paola Massari, who is working on the vaccine. “And at the same time, if you get results, you are curing a disease (in koalas).”
Meanwhile, pigs are helping scientists make more lungs available for transplants,reports STAT News.
By connecting a damaged donated human lung to a pig’s liver, kidney, and circulatory system, it can remain viable for much longer than they can on perfusion machines, because “the pig performs as a natural bioreactor to allow repair of the donated lungs.”
In addition to organ transplants, this technology could be used when studying stem cells, drugs to regenerate organs, or repairing other injured organs.
Bringing it back to COVID-19, one of the most interesting innovations in treating and preventing the coronavirus is coming from cows—specifically, SAB Biotherapeutics’ biotech cows, which can produce fully human antibodies at the numbers needed for therapeutics and vaccines.
This is why policy matters.One Health policies can support research into links between the health of humans, animals, and the environment, while modern animal biotech regulations can ensure eventual innovations can get to patients.
