Opthalmia neonatorum prevention - THE CORRECT ANSWER -
Neomycin ointment applied to newborn's eyes
Staphylokinase - THE CORRECT ANSWER -lyses blood clots, releases
staph from wounds
Hyaluronidase - THE CORRECT ANSWER -lyses connective tissues
Lipase - THE CORRECT ANSWER -breaks down lipids
Staph virulence factors - THE CORRECT ANSWER -Coagulase,
catalase, pyrogenic, hyaluronidase, lipase
Mycolic acids - THE CORRECT ANSWER -chains of 60-90 carbon
atoms producing a waxy lipid
Virulence factors of mycolic acids - THE CORRECT ANSWER -- slow
growth (ab resistance)
- protection from lysis after phagocytosis
- intracellular growth
- protection from dessication
- resistance to gram stain, detergents, antibiotics
,TB prevalance - THE CORRECT ANSWER -Estimated 1/3 of population
is infected; 5% of infections develop disease; disease is fatal to 50%.
1,000,000 new cases per year; 4th leading cause of death by infection
Mycobacterium TB morphology - THE CORRECT ANSWER -bacillus
(rod)
Mycobacterium TB motility - THE CORRECT ANSWER -non-motile
Mycobacterium TB gram status - THE CORRECT ANSWER -gram-
positive (barely)
Mycobacterium TB catalase status - THE CORRECT ANSWER -
catalase positive (aerobic)
Mycobacterium TB DNA base pairs - THE CORRECT ANSWER -High
G+C
Observations for pathogen identification - THE CORRECT ANSWER -
Morphological (size and shape) and motility
Differential testing for pathogen identification - THE CORRECT
ANSWER -- Gram status
- chemical reactions
- plating observations, selective or differential
5 Steps to infection - THE CORRECT ANSWER -1. Entry
2. Attachment
3. Invasion
4. Evasion
, 5. Exit and transmission
Pathogen methods of immune evasion - THE CORRECT ANSWER -
Becoming intracellular and hiding through antigen masking, mimicry, or
variation
Direct methods of infection - THE CORRECT ANSWER -Person to
person, animal, environment, vertical
Indirect methods of infection - THE CORRECT ANSWER -Airborne,
mechanical (contaminated objects), vector biological, vector mechanical
Pathogenicity - THE CORRECT ANSWER -ability of a microbe to cause
disease
Virulence - THE CORRECT ANSWER -ease of a pathogen to infect host
and cause disease
Paraenteral entry - THE CORRECT ANSWER -Does not involve GI
tract, needles most common
AIIR facility - THE CORRECT ANSWER -airborne infection isolation
room; pressurized room to keep air from escaping
Strep gram status - THE CORRECT ANSWER -Gram-positive
Strep motility status - THE CORRECT ANSWER -non-motile
Strep morphology - THE CORRECT ANSWER -cocci in pairs or chains
