BIOS242 Week 7 Check In Review

What was the primary objective of the USPHS Untreated Syphilis Study at Tuskegee?

To record the natural progression of untreated syphilis in Black men.

Think: Tuskegee = study untreated disease, not cure it.

Why was the Tuskegee study unethical?

Participants were not fully informed about the study's purpose and risks.

Think: No proper informed consent.

What were participants falsely told instead of being told they had syphilis?

They were told they had 'bad blood.'

Think: Bad blood = deception.

What choice were participants not given in the Tuskegee study?

They were not given the option to withdraw from the study at any time.

Think: Informed consent includes the right to leave.

What happened as a result of the ethical violations in the Tuskegee study?

The study was stopped, and participants were provided medical care.

Think: Public outcry → study stopped + care.

How did the Tuskegee study affect public trust in medical research?

It significantly decreased public trust.

Think: Unethical research → less trust.

What pathogen causes whooping cough?

Bordetella pertussis.

Think: Bordetella = cough.

What pathogen causes cysticercosis?

Taenia solium.

Think: Taenia = tapeworm → cysts.

What pathogen causes Giardia?

Giardia duodenalis.

Think: Giardia = Giardia.

What pathogen causes a vaginal yeast infection?

Candida albicans.

Think: Candida = yeast/fungus.

What type of microorganism causes whooping cough?

Bacterium.

Think: Bordetella pertussis = bacterium.

What type of organism causes cysticercosis?

Helminth.

Think: Taenia solium = parasitic worm.

What type of microorganism causes Giardia?

Protozoan.

Think: Giardia = single-celled eukaryotic parasite.

What type of microorganism causes a vaginal yeast infection?

Fungus.

Think: Yeast = fungus.

Which disease is characterized by flatulence and watery diarrhea?

Giardia.

Think: Giardia = gas + watery diarrhea.

Eggs from which pathogen develop into cysts in tissues such as the brain, muscles, eyes, and skin?

Taenia solium.

Think: Taenia → tissue cysts.

Which disease can cause seizures, headache, dizziness, and altered mental state?

Cysticercosis.

Think: Cysts in the brain → neurological symptoms.

Which disease begins with cold-like symptoms such as runny nose, fever, and mild cough?

Whooping cough.

Think: Whooping cough starts like a cold.

Which disease is treated with azithromycin?

Whooping cough.

Think: Antibiotic → bacterium → Bordetella.

Which pathogen is an intestinal parasite found in the U.S. and globally?

Giardia duodenalis.

Think: Giardia = intestinal parasite.

Which pathogen is transmitted through the oral-fecal route?

Taenia solium.

Think: Taenia eggs → fecal-oral transmission.

Which pathogen is transmitted through the oral-fecal route?

Giardia duodenalis.

Think: Giardia = fecal-oral.

Is Bordetella pertussis eukaryotic?

No — it is prokaryotic (a bacterium).

Think: Bacteria = prokaryotes.

Is Taenia solium eukaryotic?

Yes.

Think: Helminths = eukaryotic.

Is Giardia duodenalis eukaryotic?

Yes.

Think: Protozoa = eukaryotic.

Is Candida albicans eukaryotic?

Yes.

Think: Fungi = eukaryotic.

Which microbe normally lives in small amounts in the human body but can overgrow and cause disease?

Candida albicans.

Think: Candida = normally present → overgrowth → yeast infection.
