A new study has found that a single spore of the fungus Aspergillus fumigatus can cause a deadly infection in mice. The study, published in the journal Nature, suggests that the fungus is more dangerous than previously thought and could be responsible for more cases of aspergillosis, a serious lung disease. The researchers exposed mice to a single spore of A. fumigatus and found that the animals developed aspergillosis within a few weeks. The spores were also able to spread to other parts of the body, including the brain and liver. The study's findings could have implications for the diagnosis and treatment of aspergillosis. Doctors may need to be more vigilant in looking for signs of the disease in patients who have been exposed to A. fumigatus, and new treatments may be needed to prevent the disease from spreading.
