Microbiology Intro

Question 1

Subsets of Microbiology

Answer 1

Virology, Mycology, bacteriology, parasitology, molecular biology, immunology, gentics and biotechnology, diagnostic microbiology (ID microorganisms from samples), eitology (what pathogen causes symptoms) and environmental (aseptic lab techniques)

Question 2

Pathogenesis of Infection

Answer 2

Interactions between a microoorganism and the hosts’ responses

Question 3

Antimicrobial

Answer 3

Groups of mediciones used to treat bacteria (antibiotics), viruses (antivirals) and fungi (antifungal)

Question 4

Prokaryotes Def

Answer 4

Simple organisms with no true nucleus, no membrane enclosed organelles (only ribosomes), with a cell wall

Question 5

Gram Positive Bacteria

Answer 5

Thick glycopeptin cell wall. Harder for penicillin to permeate due to concentration

Question 6

Gram Negative bacteria

Answer 6

Thin glycopeptin cell wall with thin outer level

Question 7

Eukaryotes Def

Answer 7

Complex organisms with a true nucleus and membrane enclosed organelles. No cell walls

Question 8

Types of Fungi

Answer 8

Branched filaments (mold), unicellular (yeast) and dimorphic (branched filaments and unicellular)

Question 9

Viruses Rough Outline

Answer 9

Intracellular parasites (dependent on host to reproduce). Can contain DNA or RNA (not both)

Question 10

Prions Def

Answer 10

Proteins formed incorrectly in body become pathogenic. Don’t contain nucleic acid. Lead to plaques and spongiform

Question 11

Parasite Examples

Answer 11

protozoa, helminths (worm) and arthropods (insects)
