His activity presents experimental results obtained when a suspected pathogen was tested and asks you to identify appropriate co
nclusions based on each scenario. A rabbit was found to have floppy ear disease, which causes long-ear infections. Its etiology (cause) is unknown. Unknown Microorganism X from the infected rabbit's right ear is successfully isolated and cultured on laboratory growth media. The ear of a healthy laboratory mouse is then inoculated with isolated microorganism, and after a period of time, no disease is observed. Which of the following statements accurately describe(s) the conclusion(s) that can be drawn from this experiment?
Microorganism X might not be linked to floppy ear disease, because the inoculated mouse remained healthy
A laboratory mouse might not be an appropriate, susceptible host; an experiment with a laboratory rabbit may be needed.
A laboratory mouse might not be an appropriate, susceptible host; an experiment with a laboratory rabbit may be needed.
Explanation:
Pathogens are disease causing organisms and in most of the cases, they are host specific,
In this case, the pathogen (microorganism X) was isolated from an infected rabbit's ear and cultured. Th most suitable host to test the pathogenicity of the microbe would have been a rabbit because that is where it was isolated initially.
<em>A mouse might not be a susceptible host, an experiment with a laboratory rabbit may be needed to affirm the pathogenicity of the isolated organism.</em>
