Quiz Answer Key and Fun Facts

1. Streptococcus infections can cause all of the following EXCEPT:

Answer: Tetanus

Tetanus is caused by Clostridium tetani. Tetanus can grow in deep wounds and can be prevented by immunization.

2. All of these bacterial diseases are spread by ticks EXCEPT:

Answer: Typhoid Fever

Typhoid Fever is spread by contaminated food or water. Relapsing Fever can be spread by ticks or lice.

3. A PPD skin test is used to diagnose which of the following?

Answer: tuberculosis

About 20% of patients with active TB have negative PPD tests due to suppression of the immune response.

4. All of the following statements about leprosy are true EXCEPT:

Answer: Skin lesions typically spare the eyebrows.

Leprosy typically involves the face, particularly the nose, ears and eyebrows. Eyebrow loss is frequent. Warmer areas of the skin such as the scalp, armpits and between the legs are usually spared.

5. Which of these statements is true about food-borne botulism?

Answer: Antitoxin treatment blocks attachment of toxin to nerves.

Toxin already bound to nerves is unaffected but free toxin can be bound by antitoxin to prevent further paralysis. Antibiotic treatment is unnecessary because the bacteria grew in the food and produced the toxin there. Antibiotics affect bacteria - not toxins. Eye muscles are first affected followed by muscles in the extremities. Mental status is unaffected. Paralysis of respiratory muscles may lead to death.

6. Rocky Mountain Spotted Fever is most common in which state?

Answer: North Carolina

Howard Ricketts first described the disease in the early 1900s in a Montana valley, hence the name. After the disease was named it was found to be more common along the East Coast. In the years 1994-1998 North Carolina had 633 cases. Montana - 17, Colorado - 13, Minnesota - 4, California - 3

7. All of the following statements about endocarditis are true EXCEPT:

Answer: Antibiotic prophylaxis can prevent most cases.

Antibiotics prevent about 10% of cases. A couple of reasons for this are: (1) Only about half of patients have known predisposing lesions and thus aren't given prophylaxis. (2) About a third of organisms causing endocarditis are not affected by the standard drugs given.

8. All of the following statements are true about Legionnaires' Disease EXCEPT:

Answer: It is most commonly diagnosed in underdeveloped countries.

Underdeveloped countries may have little heated water. Or they may lack the means to establish the diagnosis.

9. Which of the following statements about bacillary dysentery caused by Shigella is true?

Answer: Inhabitants of custodial institutions are at highest risk.

Shigella is only found in humans and higher primates. It is most commonly seen in late summer and early fall. Flecks of blood are typically found in the diarrhea.

10. All of the following statements about meningitis are true EXCEPT:

Answer: Escherichia coli is the most common cause of meningitis in newborns.

Group B Streptococcus is the most common cause of meningitis in neonates. H. flu immunization began in the 1990s and has reduced the most common cause of meningitis in adolescents and children by 94%. The median age of meningitis has changed from 15 months to 25 years since immunization began. Neisseria meningitidis is the only bacteria that causes outbreaks of meningitis.

The search for contacts of patients with N. meningitidis periodically makes the news.
