What Is Rickettsia.

What Is Rickettsia? Rickettsia are bacteria, which are obligate intracellular parasites many disease-causing, that win in vertebrates and are transmitted by bloodsucking epenthetic arthropods such as fleas , lice and chips. Rickettsias are named after their discoverer, the American diagnostician Harold Taylor Ricketts, who died of typhus in Mexico after confirming the infectious booster shot of that rickettsial disease. Rickettsias unlike other bacteria, but like viruses, they pray a living master of ceremonies (a living cell) to survive. Rickettsias from infected vertebrates, usually mammals, live and multiply in the gastrointestinal tract of an arthropod aircraft common carrier but do not cause disease in that location; they are transmitted to some other vertebrate, possibly ch antiophthalmic factorion of another species, by the arthropods mouthparts or faeces. The cells are extremely subtile (0.25 um in diameter) rod-shaped, cocci and often pleomorphic microo rganisms which have characteristic bacterial cell walls, no flagella (except for Rickettsiae prowazekii), are gram-negative and multiply via binary program fission only inside host cells. They occur singly, in pairs, or in strands.
