Flashcards in Rickettsia Deck (23):
1

General characteristics: all types

True pathogens and obligate intracellular parasites

2

Penetration of skin

Can quickly reach the blood stream, when this happens, it attacks the cells and brings vascular obstruction leading to ischemia,
Fevers that last several days and skin rash

3

Embalming consideration

Discoloration, dehydration, anemia

4

Ischemia

When part of the body dies, because there is no blood supply

5

Epidemic typhus fever

Rickettsia prowazekii
(World Wide)

6

Pathogenicity

Obligate aerobic
Severe form, commonly found after war (louse borne,lice and fleas)

7

Portals of entry and exit (rickettsia prowazekii)

Skin,death from high fever and myocardial and neurological involvement

8

Modes of transmission
( rickettsia prowazekii)

Bite of body louse( lice)
The lice ingests the microbe and defecates on the skin of the person and can re-infect the host

9

Endemic (murine) typhus fever

Rickettsia Typhi ( world wide)

10

Murine

Mouse or rodents

11

Pathogenicity ( rickettsia typhi)

This is a mild form of flea borne

12

Portals of entry and exit ( rickettsia typhi)

Skin and respiratory system

13

Modes of transmission
( rickettsia typhi)

Bite of a rat flea

14

Rocky Mountain spotted fever

Rickettsia Rickettsii
( Western Hemisphere)

15

Pathogenicity (rickettsia rickettsii)

Tick borne

16

Portals of entry and exit:(rickettsia rickettsii)

Skin
Death to hypotension and cardiac arrest

17

Modes of transmission ( rickettsia rickettsii)

Bite of an American dog tick, line star tick, Rocky Mountain wood tick

18

Fever

Coxiella Burnetti

19

Pathogenicity ( coxiella burnetti)

Can be a spore in soil, and survives many disinfectants, resistant to heat, dryness and sunlight ( air borne animal particles, airborne transmission)

20

Portals of entry and exit ( coxiella burnetti)

Skin and respiratory system

21

Modes of transmission ( coxiella burnetti)

To animal by tick and to humans by direct contact with animal ( goats,sheep, or cattle)
Ingestion of raw contaminated milk, bioterrorism

22

Embalming concerns ( all type)

Skin rash may cause problems of discoloration; ischemia may cause distribution and diffusion problems

23

Other concerns with embalming
( all type)
