- wound infections
diarrhea - green, malodorous, liquid stool.
- how do you diagnose aeromonas hydrophila?
- Oxidase Pos reaction - it grows well on enteric media, but all enteric bugs are oxidase neg.

- Wound infections from animal bites.
- What 4 features are used for distinguishing P. multocida?
- 1. GS shows GNBs with bipolar staining - safety pin-like.
2. Penicillin susceptible.
3. Oxidase positive.
4. No growth on MAC agar.
- What pathogenic bacteria is easily transmitted by aerosol?
