His activity presents experimental results obtained when a suspected pathogen was tested and asks you to identify appropriate conclusions 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.
