Caused by f ungus found in soil in the eastern and central US. Infection occurs by inhalation of spores. Once inhaled, fungus grows and may disseminate through blood to other organs. Incubation period 30 to 100 days, although infection can be asymptomatic. Pulmonary Blastidiomycosis Resolves on its own in most people. In immune compromised can cause respiratory failure. Disseminated Blastidiomycosis If disseminates from lungs, can result in wart-like or recessed skin lesions (cutaneous blastidiomycosis) or damage to bones (osteoarticular blastidiomycosis). AIDS patients are prone to develop meningitis from infection. Images: Public Health Image Library ( PHIL ) #3768, #492 & #5801 From the Virtual Microbiology Classroom on ScienceProfOnline.com

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
