there is an immunity for rickettsia prowazekii after an attack. T/F
False
there is no immunity after an attack of rickettsia typhi. T/F
Trachoma
this attacks the cells lining the cornea and conjunctiva
Rickettsia
this invade the reticuloendothelial system, colonizing the endothelial lining of the cells of the wall of the blood vessels - small arteris and capillaries.
Lymphogranuloma Venereum
this is a sexually transmitted disease similar to gonorrhea and is only found in humans.
Chlamydia
this is another genus of bacterial like organisms that are obligate intracellular parasites.
Chlamydia Tachomatis
this is the etiological agent of - trachoma - lymphogranuloma venereum - non-gonococcal urethritis (NGU) or non-specific urethritis (NSU)
Trachoma
this is the worlds leading cause of blindness/visual disability endemic in underprivilaged areas.
Coxiella Burnettii
this organism does NOT fit the profile of other rickettsia. - No insect vector - No fever or rash
Coxiella Burnettii
this organism is a zoonotic agent of: - goats - cattle - sheep
Rickettsia
vasculitis occurs and is spread all over the body, resulting in a skin rash and pathological changes that can be fatal.
