At wildlife hospitals across eastern Australia, many koalas brought in have distinctive brown patches on their bottoms – a sign of urinary incontinence(失禁) and a painful inflamed(发炎的) bladder. Others have red, weeping(流泪的) eyes, pointing to(表明，指向) a bacterial disease that can cause blindness in the endangered marsupials(有袋类动物).
在澳大利亚东部各地的野生动物医院里，许多被送来的考拉臀部都有明显的棕色斑块——这是尿失禁和膀胱疼痛发炎的迹象。另一些考拉眼睛发红、流泪，这表明它们感染了一种细菌性疾病，这种疾病可能导致这种濒危有袋类动物失明。
Chlamydia infection, also known as chlamydiosis(衣原体病), is the most significant disease affecting the animals. The culprit(罪魁祸首) is most commonly the bacterium(细菌（单数）) Chlamydia pecorum, which is spread via(通过……传播) mating or close contact.
衣原体感染，也称为衣原体病，是影响这些动物最严重的疾病。罪魁祸首最常见的是鹦鹉热衣原体，它通过交配或密切接触传播。
“Relatively inevitably(不可避免地), infected females will become infertile(不育的), and quite rapidly,” says Mark Krockenberger, a professor of veterinary(兽医的) pathology at the University of Sydney.
“相对而言不可避免的是，受感染的雌性会变得不育，而且相当迅速，”悉尼大学兽医病理学教授马克·克罗肯伯格说。
