What’s the difference between a true pathogen and an opportunist?
true pathogens cause disease in immunologically normal people
opportunist - causes disease in immunologically compromised people; may even be part of normal flora
Which fungus is found in the Ohio River and Mississippi River valleys?

Rhizopus causes what?
mucormycosis
S. Central & Midwestern U.S.
blastomycosis
opportunistic pathogen that commonly causes esophageal disease
C. albicans
most common cause of fungal meningitis
cryptococcosis
bird droppings
histoplasmosis
invasive disease of sinus, orbits, lungs
mucormycosis
causes chronic pulmonary infection; if disseminated, affects skin, bones, and urogenital system
blastomycosis
can cause disease of vulvovaginal area in 75% of women during their lives
C. albicans
Normally this is an opportunistic pathogen that impacts immunocompromised people, but there is a species that is particular to the Pacific NW that can cause disease in immunocompetent people
in immunocompromised: Cryptococcus neoformans
in PNW/immunocompetent people: C. gattii
This disease has a very poor prognosis in diabetic/immunocompromised, and is pretty bad even in immunocompetent people
mucormycosis
skin involvement is raised, verrucous lesions
blastomycosis
