Researchers in Uganda identified where dangerous fungal organisms that cause meningitis live in the environment. They tested droppings from birds and chickens, and bark from eucalyptus trees. They found that a harmful fungus called Cryptococcus neoformans was present in marabou stork droppings and eucalyptus tree bark, but not in chicken droppings or another related fungus species called C. gattii. This helps explain why some people in Uganda get cryptococcal meningitis, a serious brain infection.
