|
majority of a parasite species can be found within just a few or a minority of the host species individuals |
aggregated or overdispersed |
|
|
host behavior modification |
ants consume flatworm larva, goes to brain, move to higher grass to be eaten by cows |
|
|
taxa |
group of organisms based off of shared characteristics |
|
|
phylogenetic characteristics |
molecular,structural, ecological, or geographical |
|
|
PRR & PAMP |
PAMP stimulate PRR to secret peptides, which stimulate phagocytosis or compliment |
|
|
TLR |
recognizecarbohydrate, polynucleotides, and protein PAMPs |
|
|
ELISA |
Well coated with antigen, test serum added, removed, and washed. Antibodies conjugated to enzyme added. Add substrate for enzyme, and measure color reactions |
|
|
Parasite eluding immune system |
Malaria, molecular mimmicry |
|
|
Parasitoid |
Typical parasite in beginning of development, finally kills host during/at completion |
|
|
Difinitive Host |
Host for parasite while reproduction takes place |
|
|
Night soil |
hookworm |
|
|
incomplete immunity |
host can prevent reinfection or superinfection, but cant get rid of all parasites |
|
|
APC |
Antigen Preventing cell, such as macrophage or dendritic cell that partially digests antigen |
|
|
Cytokines |
Protein hormones produced by one cell used to modify physiological conditions of cells that produce it and/or other cells |
|
|
T Cells |
lymphocytes used for communication between cells during immune response, regulate response |
|
|
Antibodies |
immunoglobulins produced by plasma B cells that bind to specific antigen |
|
|
memory cells |
long lived lmphocytes with specific antibodies or receptors on their surface |
|
|
skin test |
schistosomiasis |
|
|
3 plasma membrane |
Pellicle, gregarine parasites may have with supporting pellicular microtubules |
|
|
Snail, fish, bird |
Parasites exploiting trophic relationships between various host species |
|
|
Dipstick Sandwich ELISA |
antibody to antigen absorbed onto a stick, specific antigen placed above antibody, strips dripped into hemolyzed blood, antibody bound to a color reagent used |
|
|
Pathogenic effects of parasites |
1) Trauma- hookworm damaging blood vessel 2) Toxin Production- produce hemozoin 3) Nutrition Robbing- tapeworm taking vitamin b12 4) Interactions of host response- schistosome eggs in liver, blocking blood flow |
|
|
Mastigont |
Axoneme of cilium or flagella together with basal fibrils and organelles |
|
|
Pellicle |
This translucent secreted envelope covering most protozoa |
|
|
hydrogenosome |
small organelle in some anaeroboc protozoa that produce molecular hydrogen for energy |
