Unit 6

Objectives

In this unit we will study the pathogenic fungi that cause disease, parasites that use humans as their definitive hosts and viruses that afflict.

Mycology

1. Compare/contrast the fungi with other organisms.
2. Classify fungi based on reproduction and pathological properties.
3. Describe the conditions that promote growth of fungi.
4. Compare/contrast the agent, location, symptoms, treatment, and unique characteristics of the following systemic mycoses:
   • North American Blastomycosis
   • Coccidioidomycosis
   • Histoplasmosis
   • South American Blastomycosis
   • Candidiasis
   • Cryptococcosis
5. Compare/contrast the agent, location, symptoms, treatment, and unique characteristics of the following subcutaneous mycoses:
   • Sporothrix schenckii
   • Chromoblastomycosis
   • Mycetoma
6. Identify the spread, symptoms and treatment of the following cutaneous mycoses (Trichophyton, Microsporum, and Epidermophyton):
   • Tinea capitis
   • Tinea cruris
   • Tinea barbae
   • Tinea pedis
   • Tinea corporis
   • Tinea unguium
7. Identify the spread, symptoms and treatment of the following superficial mycoses:
   • Tinea versicolor
   • Piedras
8. Identify the spread, symptoms and treatment of the following opportunistic mycoses:
   • Pneumocystis pneumonia
   • Zygomycosis

Parasitology

1. Distinguish between Protozoans and Metazoans.
2. Characterize the Protozoans based on motility. List the identifying Phylum characteristics of the protists that are parasites of man.
3. Explain the significance of both the cyst and trophozoite stages of protozoans.
4. Distinguish intermediate host from definitive host and ova (egg) from larva.
5. For each of the protozoan and metazoan diseases discussed:
   • Match both scientific and common names of the parasite.
   • List distinguishing characteristics of the etiological agent.
   • Explain ways in which the disease is transmitted and how transmission can be prevented.
   • Indicate any reservoirs of infection.
   • List key symptoms of the disease.
   • Indicate classes of chemotherapeutics suitable for treatment.
     

Virology

1. For the viral diseases discussed identify the:
   • Causative agent
   • Disease caused
   • Portal of entry
   • Symptoms
   • Transmission/prevention
   • Reservoirs
   • Predisposing conditions
   • Status of vaccines/treatments
