Flashcard 9: What factor explains Mycoplasma's inability to Gram stain?

Answer: no cell wall!

Flashcard 10: What is the Gram stain and morphology of Nocardia spp.?

Answer: Gram-positive branching filaments

Extra: Key features of Nocardia: - Aerobe - Weakly acid-fast (modified Ziehl-Neelsen stain) - Found in soil - Clinical: Pneumonia/brain abscess in immunocompromised; cutaneous infections after trauma in immunocompetent. - Treatment: Sulfonamides (e.g., TMP-SMX)
