(they are ways of distributing pathogens) - What do septicemia, viremia, and toxemia have in
common and I think the answer is none of the above
100 pathogens is enough to cause disease in 50% of the host population
ID50 - measurement that is determined by the # of microbes required to give 50% of a population the
disease - Pathogen X has an ID50 of 100, what does that mean
Acquisition of resistance - Spontaneous mutation - occurs when a mutation causes a bacteria to
become resistant to a particular antibiotic
Gene transfer → bacteria can exchange plasmids that contain resistance genes (R plasmids)
What are these examples of?
Antibody- dependent cellular - binding of several IgG antibodies signals the binding of a NK
(natural killer) cell
are all leukocytes - Neutrophil, basophil, eosinophil, macrophage
Artificially acquired immunity - same process except for the antigen is deliberately introduced by
injection, orally, or nasally (immunization)
Attenuated vaccines - weakened form of a microo or virus, can still replicate in the host
Robust I.R. due to the replication of the infectious agent-answe
attractant - chemical is desirable and the bacteria moves towards it
autoclave - uses wet heat/heated steam to kill pathogens
Autoimmune disease - when I.S. responds to self generated antigens
, Auxotroph - mutant cell that requires an additional growth factor
B memory cells - What cells are responsible for the secondary response of the adaptive immune
system
Bone marrow - where are B cells made?
chemotaxis - movement towards or away from a particular chemical
chronic infection - a sickness that lasts for months or years
cold - What is caused by a rhinovirus
DNA-mediated transformation - gets naked/section of DNA from environment
Domagk - German non-nazi that discovered sulfonamides
first line of defense - Epidermis of the skin
The normal flora of bacteria that are found on your body
Mucus membrane
Antimicrobial secretions produced by cells of the mucus membrane
All of the above
Fleming - discovered penicillin
frameshift mutation - when a nucleotide is inserted or removed from the DNA sequence all of the
codons after that point are shifted (moving the reading frame)
