It\u2019s just ridiculous,\u201d Tabart said on Friday.<\/p>\n<p class=\"mb-4 text-lg md:leading-8 break-words\">Tabart\u2019s foundation estimates there are fewer than 100,000 koalas in the wild. The government-backed National Koala Monitoring Program estimated last year that there were between 224,000 and 524,000 koalas.<\/p>\n<p class=\"mb-4 text-lg md:leading-8 break-words\">\u201cI accept that chlamydia is an issue for koalas, but I also want people to understand that they\u2019re sick because they haven\u2019t got any habitat,\u201d Tabart said.<\/p>\n<p class=\"mb-4 text-lg md:leading-8 break-words\">The Queensland Conservation Council, an umbrella organisation for more than 50 environmental groups across the state, welcomed the vaccine. But the council&#8217;s director, Dave Copeman, echoed Tabart\u2019s focus on preserving koala habitat.<\/p>\n<p class=\"mb-4 text-lg md:leading-8 break-words\">\u201cIt\u2019s really good news.

Chlamydia can cause urinary tract infections, infertility, blindness and death.<\/p>\n<p class=\"mb-4 text-lg md:leading-8 break-words\">Treatment with antibiotics can disrupt an infected koala\u2019s ability to digest eucalyptus leaves, its sole food source, leading to starvation, the university said in a statement.<\/p>\n<p class=\"mb-4 text-lg md:leading-8 break-words\">Related<\/p>\n<p class=\"mb-4 text-lg md:leading-8 break-words\">The research has been supported by the federal, New South Wales and Queensland governments.<\/p>\n<p class=\"mb-4 text-lg md:leading-8 break-words\">Federal Environment Minister Murray Watt said his government had contributed to the vaccine\u2019s development through a 76 million Australian dollar (\u20ac43 million) Saving Koalas Fund.<\/p>\n<p><img alt=\"A Koala is seen being treated for chlamydia at the Endeavour Veterinary Ecology at Toorbul, north of Brisbane, Australia.\" loading=\"lazy\" width=\"808\" height=\"539\" decoding=\"async\" data-nimg=\"1\" class=\"rounded-lg\" style=\"color:transparent\" src=\"https:\/\/www.newsbeep.com\/ca\/wp-content\/uploads\/2025\/09\/562af6b53eea460e44fbfcf5c2e487af.jpeg\"\/><\/p>\n<p> A Koala is seen being treated for chlamydia at the Endeavour Veterinary Ecology at Toorbul, north of Brisbane, Australia.   &#8211; Darren England\/AAP Image via AP <\/p>\n<p class=\"mb-4 text-lg md:leading-8 break-words\">\u201cWe know that koalas need help to fight diseases like chlamydia. It\u2019s a widespread threat impacting their reproductive health and causing infertility,\u201d Watt said in a statement.<\/p>\n<p class=\"mb-4 text-lg md:leading-8 break-words\">Koalas are iconic Australian marsupials, like wombats and kangaroos. They spend most of their time eating and sleeping in eucalyptus trees, and their paws have two opposing thumbs to help them grasp and climb up tree trunks.<\/p>\n<p class=\"mb-4 text-lg md:leading-8 break-words\">Australia\u2019s wild koala populations have declined steeply in the past two decades.<\/p>\n<p class=\"mb-4 text-lg md:leading-8 break-words\">Facing compounded threats from disease, habitat loss, climate change and road collisions, koalas could become extinct by 2050, according to a 2020 assessment from the New South Wales government.<\/p>\n","protected":false},"excerpt":{"rendered":"A regulator has approved a world-first vaccine to protect koalas from chlamydia infections, which are causing infertility and&hellip;\n","protected":false},"author":2,"featured_media":138165,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[10],"tags":[2840,49,48,72107,74751,84,52057,72106],"class_list":["post-138164","post","type-post","status-publish","format-standard","has-post-thumbnail","category-health","tag-australia","tag-ca","tag-canada","tag-chlamydia","tag-deborah-tabart","tag-health","tag-koalas","tag-peter-timms"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/posts\/138164","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/comments?post=138164"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/posts\/138164\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/media\/138165"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/media?parent=138164"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/categories?post=138164"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/tags?post=138164"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
