Usually, these fungal spores might be inhaled via mud when soil is disturbed and can settle inside the lungs the place they then remodel into bigger, multicellular buildings known as spherules. Spherules leech off the vitamins within the lungs and develop till they burst, releasing extra spores. These spores repeat the method, inflicting the fungus to vastly multiply inside the lungs. This multiplication might result in spreading of the spores outdoors of the lungs and all through the pores and skin, bones and the membranes surrounding the mind, inflicting meningitis.
