In contrast, the stony creek frog did not noticeably decline at any elevation.<\/p>\n<p>&#8220;The reasons for these differences among species and populations are not entirely clear, but variations in microbiomes\u2014the bacteria, fungi, and other microorganisms on the frogs\u2014may play a key role,&#8221; said Dr. McKnight.<\/p>\n<p>Scientists examined both the bacterial and fungal microbiomes of four Australian frog species from the same area which had different responses to chytridiomycosis.<\/p>\n<p>They found microbiomes were different for each frog species and that they may have played a role in patterns of declines and recoveries.<\/p>\n<p>&#8220;The species that has shown the lowest ability to recover, lace-lids, was also the species with the fewest types of bacteria and fungi present on it. That matches what some other studies have found and suggests that diverse microbiomes may be important.<\/p>\n<p>&#8220;What was really surprising, however, was that lace-lids also had high levels of anti-fungal bacteria that are thought to play a protective role against chytridiomycosis. In fact, the individuals with the highest levels of chytridiomycosis also tended to be the individuals with the highest levels of anti-fungal bacteria,&#8221; said Dr. McKnight.<\/p>\n<p>He said the relative abundance of what had been thought of as protective, anti-fungal bacteria was highest in the Australian lace-lid frog and lowest in the waterfall frog despite the fact that lace-lid populations have not recovered but waterfall frogs largely have.<\/p>\n<p>Dr. McKnight said the findings present scientists with more questions and a variety of possible answers.<\/p>\n<p>&#8220;For instance, it may be that the presence of the fungus that causes chytridiomycosis actually causes anti-fungal bacteria to thrive, or there may be some other factor in the frogs&#8217; environment that favours both the bacteria and the pathogen. Or possibly only frogs with high levels of anti-fungal bacteria can survive high infection loads,&#8221; said Dr. McKnight.<\/p>\n<p>He said the research has important conservation implications.<\/p>\n<p>&#8220;In laboratory trials, seeding amphibians with anti-fungal bacteria (probiotics) often reduces mortality and allows frogs to clear infections or reduce infection intensity.<\/p>\n<p>&#8220;So, probiotics are widely considered a promising strategy for mitigating the disease in wild populations and assisting population recoveries. Unfortunately, our results suggest that this strategy may not work unless probiotics use a diverse range of bacteria, and they may need to be specifically tailored for each frog species,&#8221; said Dr. McKnight.<\/p>\n<hr\/>\n<div class=\"article-main__explore my-4 d-print-none\">\n<p>                                            Bacteria in frog skin may help fight fungal infections in humans\n                                        <\/p><\/div>\n<hr class=\"mb-4\"\/>\n<div class=\"article-main__more p-4\">\n                                                                                                <strong>More information:<\/strong><br \/>\n                                                Donald T.
