"Humans acquire Staphylococcus saprophyticus from direct exposure to animals or inadequately cooked animal food products. Young women are more susceptible to genitourinary colonization than are others, and some people develop infection in association with hormonal influences that occur near or during menstruation. Sexual intercourse promotes colonization and infection. Alterations in the genital flora effected by spermicides or candidal infection favor colonization by S. saprophyticus. Anal intercourse may play a role in infection in homosexual men."

I am having trouble trying to figure out the relation between acquiring Staphylococcus saprophyticus from animals versus sexual intercourse. How are humans infected by Staphylococcus saprophyticus, and what would the symptoms of that be?

Choose correct answers: Which of the following are true of nuclear receptors?

Question 7 options:

Suppose that goats have one gene that codes for color, where A is brown and a is white. The goats also have another gene that codes for height, where B is tall and b is short. If these two genes are unlinked, what is the probability that a cross between Aa Bb × Aa bb parents will produce two out of six offspring that are brown and short? Enter your answer as a decimal, rather than as a percentage.

waht is the Number ? Number:____.

1. In the MIC assay, why did it matter what the E. coli density is? (Why was a diluted culture used to inoculate the broths?)
2. The MIC assay measures inhibition, not killing. If you wanted to conduct a Minimum Lethal Concentration, how could it be done?

Hypothesis 1: Mercury in thimerosal caused neurological damage in children, and is at least partly responsible for
the increase in autism diagnoses.

Hypothesis 2: Te rate of autism incidence is not increasing, only the rate of autism diagnoses, as greater awareness
of the syndrome and increased screening of children yields more positive diagnoses of autism.

What are the observations that led to the generation of the above hypotheses? Do both hypotheses make testable predictions? How could you test them?

Given the viral life cycle pictured, identify 3 stages of the cycle which you might target with a therapeutic molecule in order to both (i) prevent or inhibit spread of the virus, and (ii) avoid affecting human cells. Explain your choice in detail in all cases.

Explain what meat allergy (or alpha-gal syndrome) is and how it develops.
