A

GN, cocci

31
Q

Neisseria - Stain? Structure?

A

GN, cocci

32
Q

Mycobacterium - Stain? Structure?

A

Acid Fast, Bacilli

Why: Mycolic acids prevent gram staining (even though technically GP)

33
Q

Ricketssia - Stain? Structure?

A

NA, Bacilli

Why: GN cell structure, no peptidoglycan - doesn’t stain well

34
Q

Chlamydia - Stain? Structure?

A

NA, Cocci

Why: GN cell structure, no peptidoglycan - doesn’t stain well

35
Q

Chlamydophila - Stain? Structure?

A

NA, Cocci

Why: GN cell structure, no peptidoglycan - doesn’t stain well

36
Q

Mycoplasma - Stain? Structure?

A

NA, Filamentous

Why: No cell wall + very small - microscopy is useless

37
Q

Treponema - Stain? Structure?

A

Dark field microscopy, Spirochete

Why: GN cell structure, peptidoglycan too thin - doesn’t stain well

38
Q

Borrelia - Stain? Structure?

A

Wright/Giesma, Spirochete

Why: GN cell structure, thin peptidoglycan, too thin to be seen with light microscope

39
Q

Leptospira - Stain? Structure?

A

NA, Spirochete

Why: GN cell structure, thin peptidoglycan, too thin to be seen with light microscope
