Gram -
A genus rickettsia
-
obligate intra celluar parasite
A rickettsia ricketti
rocky spotted fever tick
can not use glucose as an energy source
-Pathogen avoids digestion in phagosome by escaping from the phagosome
shortly after phagocytosis and moving into the cytoso
-damge to blood vessles
A rickettsia prowazekil

CARBON FINAL ACCEPTOR
Chlamydiae
Gram -
obligate intracellular pathogens
Chlamydophila psittaci
respiratory issues
parrot fever
Zoonotic
Chlamydia trachomatis
Trachoma
STI, urethritis
C.Trachoma Reticulate body
metabolically active form
grows and multiplies inside host cells
C.Trachoma Elementary body
infective form
Smaller
Survives outside the cell
Induces endocytosis to infect a new host cell
Trachoma
inflammation eyelid
Scarring of the conjunctiva and cornea
Purulent discharge causes deformed eyelids

PCR for detection
