The trials that were conducted were a treatment, not a cure. A cure insinuates the organism is no longer susceptible to the disease, which is not the case with these treatments. A better article, that represents our research and treatments, and quotes us better, is the MNN article below.
I expect their cure to be temporary.
Fungus, if it's stopped by bacteria is due to living space and biological niche being filled.
Just like someone on lots of antibiotics is at higher risk of thrush infections (fungus) and can be helped by consuming "probiotic" foods, the inoculation will depend on the bacteria PERSISTING on the bat and staying there.
For whatever reason, bacteria that used to fulfill the role for bats is gone and the niche was exploited by the fungus.
Finding something more effective than the usual anti-fungal drugs is a breakthrough, but they might still have to make this bacteria persistent or re-spray bat housing to keep the bats healthy.
