Q

What are the two phases of Chlamydia and what are their characteristics?

A

Elementary body- infective and metabolically inactive

Reticulate body- metabolically active and replicates

*When elementary bodies get inside a cell it becomes a reticulate body. The reticulate body is metabolically active and reproduces and evetually transforms again into a series of elementary bodies that are released from the host cell and are free to infect other cells

Q

You have a dog that has a really nasty skin infection or ear infection. You do a gram stain and see a lot of white blood cells. You also see cocci and rods. What organisms come to mind if:

  1. The gram stain shows gram positive cocci
  2. You see gram negative rods
  3. If you see gram negative and gram positive cocci and rods
A
  1. If you see cocci you should be thinking either Staph or Strep
  2. Pseudomonas or E. coli if you see gram negative rods
  3. All these organisms are possiblities if gram negative and gram positive

*If you see rods, they are most likely gram negative because there are not many gram positive rods that you will see in an aerobic situation. When you see gram negative rods in a skin or ear setting Pseudomonas and E. coli should be the first organisms to come to mind. If there is only gram positive cocci, then pseudomonas and E. coli will not be the causative agent.
