“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.

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.
