1. + Other Infectious Microbes

2. + Fungi Out of thousands of species of fungus only about 50 cause disease. Diseases caused by fungi are called mycoses. Usually unicellular eukaryotes (i.e.mold)

3. + Fungus Example: Ringworm Infects the middle skin layers. Caused by the fungi: DermatophytosisDermatophytosis Transferred by skin to skin contact. Highly contagious! Symptoms: Itchy, a round rash Treatment: Antifungal creams

4. + Fungus Example: Candidiasis A.K.A. Yeast infection Caused by Candida albicans- a naturally occurring fungus. Usually controlled by bacteria in your body. Symptoms show when there is a lack of bacteria in the body. (When you are on antibiotics) Symptoms show in the GI tract or vaginal area. A yeast infection of the mouth is called thrush- usually occurs in infants. Treated by an antifungal cream

5. + Protozoans Unicellular eukaryotes Less than 20 species cause disease Usually use the body to reproduce like a bacteria. Some varieties can do photosynthesis and some behave more like animal cells

6. + Protozoan Example: Amoebiasis A parasite that survives in warm climates- especially in places with poor sanitation. 3,000-5,000 cases per year in the US Enters through food or unsanitary practices—enters through the mouth Divides in the intestine Produces ulcers, diarrhea, vomiting Spread through feces

7. + Protozoan Example: Malaria Caused by plasmodium- a parasite Carried by female mosquitoes Infects liver cells Uses erythrocytes to reproduce Erythrocytes lyse causing infectious agent to spread through the blood stream. Taken up by mosquitoes again
