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

You are my host ! I am burrowing up through your feet, to your throat, where you’ll swallow me. I live and grow, with my teeth hooked into the lining of your intestine! Ancylostoma duodenale From the Virtual Microbiology Classroom on ScienceProfOnline.com

Parasitic nematode worm (helminth) that lives in small intestine of host. Helminths belong to Kingdom Animalia. Two species commonly infect humans: Ancylostoma duodenale and Necator americanus . Infect > 600 million worldwide. Eggs in fecally-contaminated soil mature into larvae. Larvae penetrate skin of foot (sometimes causing “ground itch”), ride the lymph system to the right side of heart, and pumped into lungs, are coughed up , and are then swallowed.
