They are considered a separate group of bacteria because they have the common feature of being spread by arthropod vectors (lice, fleas, mites and ticks). The cells are extremely small (0.25 u in diameter) rod-shaped, coccoid and often pleomorphic microorganisms which have typical bacterial cell walls, no flagella, are gram-negative and multiply via binary fission only inside host cells. They occur singly, in pairs, or in strands. . cultures drawn from your patient, Mrs. I. M. Septic, are growing . gram-positive . cocci. .

The doctor asks about any insect bites and Robert tells him about getting tick bites during a camping trip one week prior to developing the first symptoms. Upon examining Robert he notes the macular rash on the arms and legs. Initial bloodwork shows that Robert has a low platelet count, low sodium levels and abnormal liver function tests.. . CHLAMYDIA.
