We are taking bets on this one! This is a gram stain from a pleural aspirate.
Answer the following:
1. What type of organism(s) do you see in this gram stain?
2. Based on this, what organism do you think will grow?
3. Why are you choosing this organism?
1. Gram negative diplococci
2. I’m guessing Moraxella catarrhalis
3. Because it is a common cause of pneumonia in pediatrics and looks like this (I think!)
1. Definitely gram negative diplococci.
2. While I do agree it's most likely M. catarrhalis, I also question if it could be Neisseria meningitidis?
3. Both are found in respiratory infections and both can be found in sputum.
