Why might it be easier to determine the bacterium that caused pneumonia than one that caused a wound infection?

#Unit 4. Cell Communication and Cell Signaling

  1. There are very few microorganisms that can cause pneumonia, while there are many that can cause wound infections.

  2. Bacteria that cause pneumonia can be identified with few tests. Many bacteria are normally found on the skin and may be in the wound complicationg indentification of the pathogen.

  3. We have much better tests for bacteria in the lungs than we do in wounds.

  4. The techniques of 16S rRNA sequencing are easier to perform on a sample taken from the lungs than a sample taken from a wound.
