NOTE: Test Monday LHA 7:30. Study Handouts and Notes

Audio for today's lecture is available here.

• Zoonoses – diseases of animals transmitted to humans
• Ex. Anthrax, rabies, avian flu
• Trichophyton rubrum (red mold)– ringworm of the foot, athletes foot. Get it from shower floors.
• Sporothrix schenkii – causes rose gardner’s disease. Soil organism. Get it by being pricked by a thorn. Looks like a red train track from original puncture towards the center of your body.
• Systemic diseases
• Coccidiodes immitis – causes valley fever. Breath it in and it spreads. Primarily in southwest US (California, Arizona).
• Treated with Amphotericin B.
• Histoplasma capsulatum – causes histoplasmosis. Grows well in soil in which bird feces are present.
• Found right down the middle of the United States. Sometimes called Mississippi valley fever
• Breath it in through the lung and then it spreads.
• Also treated with Amphotericin B.
• Aspergillus fumigatus – Fungal ball disease.
• AIDS patients will breath this in and get a fungal ball in their lungs that shows up on x-rays.
• Pneumocystis jiroveci – causes Pneumocystis Pneumonea – PCP.
• Amphotericin B (p 466) – used to treat systemic fungal infections
• Ringworm called derma(skin)tophytes(fungus) – goes after skin, hair and even nails – p498
• Coccidiodomycosis – valley fever – p 547
• Dimorphic (two forms) – ex. Histo and cocci. Grow some in blood agar it will become yeast. Grow the same stuff in sab-dex you will get a white mold.
• Mycotoxins
• Aflotoxin – caused by aspergillus flavus. Cause by rotting grains. We can come in contact with it by rotting peanut butter.
• It is a primary carcinogen – causes cancer

• PROTOZOANS – much of this information is directly from the handout he gave us today (Sep-21). I wrote down the things that stuck out to me.
• PAM - Primary amoebic meningio insephilitis
• Cryptosporidium – causes diarrhea in cows, causes cryptosporidiosis in AIDS patients. Sometimes called slims disease
