R. prowazekii
Boutonneuse Fever is characterized by the presence ofâŚ
taches noires (black spots)
typhus group of Rickettsia
R. prowazekii, and R. typhi
Cause: Human granulocytic anaplasmosis

glucose
Group of organisms once thought to be viruses because of their size
Mycoplasma
Transmitted via the bite of infected Ixodes ticks
Lyme disease
serotype D to K causesâŚ.
vaginitis, nongonococcal urethritis, epididymitis, and prostatitis, inclusion conjunctivitis
caused by R. akari

acridine orange
True or False: Mycoplasma is visible in gram staining
False
True or False: Chlamydia can multiply outside a living cell
False
True or False: Atypical bacteria means it does not color with gram staining and remain colorless
True
formerly known as TWAR strain
