How do infected individuals “fight” the Trypanosoma parasite?
Homework Answers
Trypanosoma infection causes the release of hemoglobin from from the red blood cells. Hemoglobin supports the innate immune system by binding to a small fraction of high density lipoprotein (HDL) or good cholesterol. The hemoglobin-HDL complex acts as a super toxin and helps in clearing the body of the trypanosoma parasite.

Antibodies to Trypanosoma Glycoprotein Variants Over Time Sleeping sickness is caused by the unicellular Trypanosoma parasite. The surface of this parasite is covered by glycoproteins that are encoded by a gene with more than 1,000 duplications in the trypanosome genome. Each of the gene copies is slightly different and has different molecular structures. The data below show the number of parasites over time (A) and the relative amount of antibodies specific to two trypanosome glycoproteins (B) over 24 days of...

In a certain population of mussels (Mytilus edulis), 80% of the individuals are infected with an intestinal parasite. A marine biologist plans to examine 100 randomly chosen mussels from the population. a) Find the probability that 85% or more of the sampled mussels will be infected using normal approximation to binomial distribution. b) What is the expected number of infected mussels in 50 randomly chosen mussels?

The complex metabolic pathways in the parasite Trypanosoma brucei were elucidated in part by adding radiolabeled metabolites to cultured parasites. In the parasite, glucose is converted t0 phosphoenolpyruvate (PEP) in the cytosol. PEP then enters an organelle called the glycosome and is converted to oxaloacetate (OAA); OAA is then converted to malate, and malate to fumarate. Fumarate reductase catalyzes the conversion of fumarate to succinate; the succinate is then secreted from the glycosome. If C1 of glucose is labeled, what...

If individuals with the sickle-cell hemoglobin are selected against, how is it that the mutated hemoglobin gene persists in the human population? Choose the best answer. Individuals with sickle-cell disease (recessive homozygous) are best able to fight off malaria, so the gene persists in malarious areas. The monkey bread tree is not sensitive to temperature. When a non-sickle cell individual (dominant homozygous) mates with an individual with sickle-cell disease (recessive homozygous) the produce heterozygotes and that is how the mutated...

2. Suppose that you have been assigned to study HIV-infected individuals that exhibit signs of the newly-defined Ascending Neuromuscular Weakness Syndrome (ANWS). You find that there are very many hospitals of this syndrome and that there are no obvious characteristics that suggest different signs of this syndrome. Your resources will permit an experiment with adequate replication of six treatments. How will you select infected individuals?

Imagine an island with a starting population of 100 individuals. 1 of those is infected with a deadly disease. Once infected, this disease will kill an individual in 4 days. Calculate the removal rate (γ), then using the removal rate, calculate what value of a will result in an epidemic.
