PATH 1016 Pathology and Therapeutics I - Infection (Part 1)
With Complete Solutions!!
infection - ANSWER invasion of the body by a pathogen (microorganism that causes
disease)
localized infection - ANSWER an infection that is limited to a small area
systemic infection - ANSWER an infection throughout the body; effects multiple
systems;
How is a systemic infection spread? - ANSWER through the blood
Infectious agents (pathogens) - ANSWER a pathogen with potential to cause disease
(ex. bacteria, virus, fungus, parasite)
Agents of infectious disease differ by... - ANSWER 1. structure of pathogen
2. contraction of pathogen
3. type of harm caused
4. treatment of pathogen
Prions - ANSWER infectious protein particles that do not have a genome (ie. RNA or
DNA)
Virus - ANSWER nonliving particle that invades and reproduces inside a living cell
("gene in a box")
What is a capsid? - ANSWER Outer protein coat of a virus
, Bacteria - ANSWER a unicellular prokaryotes that self replicates without a host; some
cause disease, others are benign or beneficial
Aerobes - ANSWER Bacteria that require oxygen to grow (found mostly in respiratory
tract)
Anarobes - ANSWER can't survive in oxygen (found mostly in gut)
What are the three types of bacteria shapes? - ANSWER 1. cocci
2. bacilli
3. spiral
Cocci (coccus) - ANSWER Spherical bacteria (sometimes occur in chains called
streptococci)
Bacilli (bacillus) - ANSWER Rod shaped bacteria (also threadlike or filamentous)
Spiral (spirillum) - ANSWER spiral or corkscrew-shaped prokaryote
- short ones called sprillia
- longer ones called spirochetes
What is a Gram stain? - ANSWER Stain test that measures the thickness of cell walls in
bacteria. It determines if a bacteria is gram-positive or gram negative.
Gram-negative bacteria - ANSWER Less peptidoglycan; more cell walls and more likely
to cause disease (stain red)
What kind of bacteria is more susceptible to antibiotics? - ANSWER Gram-postive
