(46 cards)
A person who harbors the etiologic agent but no apparent signs/symptoms of disease
Carrier
The origin of the etiologic agent/location
Reservoir
A living entity that transmits the etiologic agent
Vector
A non-living entity that is contaminated with the etiologic agent
Vehicle (Fomite)
A larger than normal number of diseased or infected individuals that occurs over a relatively short period
Outbreak
A larger than normal number of diseased or infected individuals in a particular location
Epidemic
How many components are there in the chain of infection?
(1) Microorganism
(2) Reservoir/Source
(3) Port of Exit
(4) Means of Transport
(5) Port of Entry
(6) Susceptible Host
Major enzyme of EMP glycolytic pathway
Pyruvate
Major enzyme of Pentose Phosphate Pathway
G6PD
Primary physical barrier
Skin
Laboratory-based characterization of etiologic agents esp for VIRUSES
Strain Typing
Measurable indications or physical observations (objective)
Signs
Indicators as described by the patient (subjective)
Symptoms
Asymptomatic; time from acquiring infection to having the first signa & symptoms
Incubation period
The relative ability of a microorganism to cause disease/the degree of pathogenicity
Virulence
Other names of Hyaluronidase
Spreading Factor
Duran-Reynal Factor
Released when gram (-) cell is destroyed & the effect is uniform
Endotoxin (Lipid A)
Toxin (acquired through transduction) that is produced & released by LIVING bacteria where the effect is specific
Exotoxin
Most potent toxin
Botulinum toxin
Test that detects gram (-) endotoxin results to clumping
Limulus Lysate Test
Who is responsible for the exposure control plan?
Microbiology supervisor & Laboratory director
Responsible for the post-exposure investigation
Microbiology supervisor & Laboratory safety officer

Sterilization & avoid over inoculation
What type of filter will give you 100% bacterial sterility?
Millipore (0.22 um) membrane filter
