1

Bird handlers are at risk for what Chlamydia disease?

Psittacosis

2

What bacteria causes Psittacosis?

Chlamydia psittaci

3

Give the most common cause of community-acquired typical pneumonia for children and adults

Children=Klebsiella pneumoniae
Adults=Streptococcal pneumoniae

4

What is the most common cause of atypical pneumonia?

Mycoplasma pneumoniae

5

How is Hantavirus transmitted?

Inhalation of rat feces and/or urine

6

List two common treatments for strep throat/laryngitis/bronchitis. These affect the cell wall of the gram positive bacteria.

Penicillin
Amoxicillin

7

Less than __% of patients diagnosed with strep throat actually have it...

50%

8

All of the following are caused by Group __ streptococcus: strep throat, scarlet fever, impetigo, toxic shock syndrome, cellulitis, necrotizing fasciitis

A

9

The bacteria responsible for causing streptococcal pharyngitis (strep throat)?

Streptococcus pyogenes

10

This bacterial disease is associated with sore throat, fever, a thick pseudomembrane in the back of the URT, and a characteristic “barking” cough.

Diphtheria

11

The pathogen for Diphtheria?

Corynebacterium diphtheriae

12

MC pathogen of sinusitis and otitis media?

Streptococcus pneumoniae

13

Other than streptococcus pneumoniae, what other bacteria often causes sinusitis and otitis media?

Haemophilus influenzae

14

List the MCC of common colds

Rhinoviruses

15

Enteroviruses infecting the nose are called?

Rhinoviruses

16

The most common type of pneumonia?

Pneumococcal pneumonia

17

A common thing done to diagnose pneumonia?

Chest X-Ray

18

Called “walking pneumonia” because of it’s more mild symptoms

Atypical pneumonia

19

Legionnaires’ disease is also called?

Legionella pneumonia

20

The unique thing about these bacteria that cause Legionnaires’ disease are that they are the only type to grow on a buffered charcoal yeast extract agar (fluorescent)

Legionella pneumophila

21

Pathogen for tuberculosis?

Mycobacterium tuberculosis

22

Tuberculosis has 3 types. List them:

Primary
Secondary
Disseminated

23

This type of TB involves the formation of small hard nodules (tubercles), and can remain dormant for years

Primary

24

A ruptured tubercle reestablishes active infection. This type of TB occurs in a previously infected patient

Secondary

25

In this type of TB macrophages carry bacterium via lymph nodes and blood to a variety of sites throughout the body (meaning the bacteria can survive and grow in these macrophages).

Disseminated TB

26

Tuberculosis is diagnosed by a tuberculin skin test called ___ for short

PPD

27

In a PPD test for TB, if the area of induration (skin reaction) is __mm in immunocompromised patients, they are positive for TB. __mm in infants, elderly, homeless, recent immigrants, alcoholics, health care workers, and prisoners is considered positive (they are high risk), while __mm in the population not belonging to the other two groups is considered positive.

5, 10, 15

28

What age group is most seriously affected by respiratory syncytial virus (RSV)?

Children <2

29

The infectious agent of Pertussis (whooping cough)

Bordetella pertussis

30

Pathogen for anthrax?

Bacillus anthracis

31

This disease most commonly affects animal handlers. It is characterized by localized itching followed by a raised lesion that forms a painless black eschar within 7-10 days

Anthrax

32

The pathogen contains glycoproteins spikes. Mutations in genes coding for these spikes are responsible for the production of new strains of the virus.

Influenza

33

Aspirin must be avoided when a person is infected with influenza virus due to the possible complication of becoming ___ syndrome

Reye’s

34

SARS stands for?

Severe Acute Respiratory Syndrome

35

The pathogen for SARS?

A Coronavirus

36

The most common pediatric respiratory disease?

Respiratory Syncytial Virus (RSV)

37

__% of Bronchiolitis cases in children are caused by RSV

75%

38

This respiratory disease is characterized by EXPIRATORY wheezing (prolonged expirations). Usually in a child <2 years old

RSV

39

Mycotic diseases are ____ infections

Fungal

40

“Valley fever” is common in the southwest US and Mexico. This lower tract disease is called?

Coccidioidomycosis

41

This is common in the southern central US (Mississippi valley). Flu-like sx. Fungus spreads causing painless lesions in the face and body.

Blastomycosis (Blastomycosis dermatitidis)

42

This is the most common fungal systemic disease. It is common in the eastern US/Ohio river valley. Sever coughing with blood-tinged sputum and skin lesions.

Histoplasmosis

43

Pathogen for histoplasmosis?

Histoplasma capsulatum

44

Where is Histoplasma capsulatum found?

Bird and bat fecal material
