Description and significance

“Rickettsia felis” is an obligate intracellular parasite that was first isolated from cat fleas. It is a gram-negative bacteria that was that differs from Rickettsia typhi by only 32 nucleotide differences3. It was identified in patients clinically diagnosed with murine typhus4. It was originally thought to be a member of the typhus group of rickettsiae, but upon sequencing was found to be closer to the spotted fever group of rickettsiae5.
