Flashcards in Microbiology Final Deck (91)
ability to exist in more than one form
originally placed in the plant family. Smallest form of animal life - not plant life. A group of diverse and wide spread unicellular and multicellular organism (dimorphism). That lack chlorophyll and usually bear spores and appear filamentous.
(study of fungi) to include yeast or mole.
superficial fungal infections seen on the skin.
Dermatomycosis causes what superficial infections of the skin?
ringworm (scalp) jock itch (genitalia)athlete’s foot (toes). most common
All of these 3 can cause these 3 fungal infections (jock itch, ringworm, athlete's foot):
1. Microsporum species2. Trichophyton species3. Epidermophyton species
Super infection (can be found within the body). You look at the genus name to determine the infection that it causes.
Systemic fungal infection
List the 5 Systemic fungal infections
1. Coccidioides immitis 2. Histoplasma capsulatum3. Candida albicans4. Cryptococcus neoformans5. Pneumocystis jiroveci
causes coccidioidomycosis found in the lungs - a systemic fungal infection in man, transmitted through the air spots on the lungs, not to confuse with TB.
cause histoplasmosis (respiratory fungal infection).
causes candidiasis (thrush) vaginal thrush - a yeast infection
causes crytococcosis, caused by pigeon droppings.
causes pneumocystis pneumonia (pcp).
the smallest form of animal life
4 types of Protozoa
1. Entamoeba histolytica 2. Plasmodium malariae 3. Toxoplasma gondii 4. Giardia lamblia
causes amoebiasis (amebic dysentery in the intestine).
causes malaria which causes red blood cells destruction. Primary host is the monkey being bitten by the anopheles mosquito and the mosquito infecting man. Mode of transmission- indirect animal to person.
causes toxoplasmosis and affects the central nervous system. This can be transmitted by cats. (CNS)
causes giardiasis (traveler’s diarrhea)
study of viruses
Characteristics of viruses
1. Smallest microorganism known to man that cannot be seen with the ordinary compound light microscope.2. Reproduce by replication.3. Contains either a SINGLE STRAND of DNA or RNA genetic structure, not both.4. Strict intracellular parasites and must obtain their food from living organic matter.5. Cannot be grown in a laboratory setting.6. Antibiotics have NO effect on them.
Important viral diseases by anatomical site
DermatropicPneumotropicNeurotropic central nervous system ViscerotropicImmunological viruses
characterized by the presence of a skin Rash
8 Types of Dermatropic viruses
1. Smallpox (Variola)2. Measles (Rubeola)3. German measles (Rubella)4. Chicken pox (Varicella)5. Shingles (Varicella zoster)6. Herpes simplex I7. Herpes simplex II8. HPV (Human Papilloma Virus)
most infectious and highest mortality rate (100% death) only historically significant and has been eliminated.
10 day (regular), childhood infection. Koplik spots lesions inside the cheeks used to detect it.
Measles (Rubeola) (Also known as hard measles)
3 day measles not as severe for adults; however, can be spread placentally, leading to birth defects in the child or still birth. It has teratogen – the virus affinity for developing fetal tissue.
German measles (Rubella)
