Q

Org?

(broad based budding yeast)

24
Q

Causative agent?

A

Pneumococcus

(this is bulging TM in otitis media)

25
Q

Organism?

A

Francisella tularensis

(oculoglandular tularemia - notice ulcer on inside of eyelid)

26
Q

Which organism transmits this way?

A

Legionella (hot tubs, air conditioning units, etc; inhaled via contaminated vapor/mist = no human-to-human transmission)

27
Q

What disease is described here?

A

Pertussis

(Bordetella pertussis)

28
Q

Org?

MTB

(ghost cells on gram stain = mycolic acid repels stain and forms what looks like outline of cells)

29
Q

Org?

A

Yersinia pestis

(“Chubby safety pin”; Gram - rod)

30
Q

This area is endemic for what org?

A

Coccidioidomycetes

(Valley fever = arid climate of SW US)

31

Pneumococcus pneumonia

(in upper right lobe)

33
Q

Org?

A

Nocardia

(G+ branching)

34
Q

Causative agent?

A

Actinomyces

(causes abscesses in cervico-facial, jaw, pulmonary, and GI regions)

35
Q

Org?

A

Influenza

(Virulence factors = NA, HA, M2, NS1)

36
Q

Organism’s lifecycle?

A

Chlamydia

37
Q

Which organism can cause disease in each of these sites?

A

Acinetobacter baumannii

38
Q

Org?

A

Coccidioidomycetes

(notice the spherule = tissue form)

39
Q

What dis is?

(Francisella tularensis)

41
Q

Org?

Q

Organism?

A

Paramyxovirus = RSV, hMPV, hPIV

(notice the syncytium formation due to fusion protein)

43
Q

These Rx treat what?

A

Influenza

(Amantadine = influenza A; olseltamivir = influenza A&B)

44
Q

Cause?

A

AdV

(if tularemia, would have pus = bacterial vs. viral; also look for ulcer inside eyelid w/ tularemia)
