b.Bronchogenic pneumonia with abscess formation (e.g., after aspiration)
which organisms

Answer 9

Candida albicans tropicalis

Question 10

the cryptococcosis microscopic appearance

Answer 10

numerous Cryptococcus neoformans organisms that have a large polysaccharide capsule, giving the appearance of a clear zone around a faint, central round nucleus This capsule inhibits inflammatory cell recruitment and macrophage phagocytosis.
The bright red organisms and surrounding capsular clear space are highlighted with the mucicarmine stain.

Answer 13

These 5- to 10-μm yeasts can become disseminated to other organs, particularly the central nervous system, often producing meningitis in immunocompromised individuals.
