other Gram negative

Answer 11

Neisseria, Rickettsiae, Chlamydiae, Borrelia, Leptospira, Treponema

Question 12

Gram stain, These Microbes May Lack Real Color

Answer 12

Treponema, (too thin, use dark field microscopy and fluro AB staining)
Mycobacteria(high lipids in cell wall- detected by carbolfuchsin in acid fast stain))
Mycoplasma(no cell wall)
Legionella pneumophila (primarily intracellular use silver stain
Rickettsia (intracellular parasite)
Chlamydia(intracellular parasite, lacks muramic acid in cell wall)

Question 24

Capsule serve as

Answer 24

antiphagocytic virulence factor, if you add protein conjugate it serves as an antigen in faccines

Question 25

encapsulated bacteria are cleared

Answer 25

by spleen and are opsonized,

Question 26

Asplenic encapsulated bacteria have a lower

Answer 26

opsonizing ability and are at risk for sever infections, (S. Pneumoniae, H. Influenzae, N. Meningitidis vaccines.
