zoonotic gram neg rods
their similarities/differences |
1. Yersinia pestis
2. Francisella tularensis 3. Brucella spp 4. Pasteurella multocida 1-3 are facultative INTRACELLULAR organisms & extremely virulent- can penetrate any body area and disseminate. Pasteurella is NOT intracellular. |
|
|
cata/dog bites
- common bugs - where else found |
Pasteurella multocida
....also in birds DO NOT close cat bite/scratches with sutures!! |
|

Bubonic plague
- cause - labs - VF - reservoir/vector - symptoms - tx |
Yersinia pestis
gram neg rod 1. F1 (Fraction 1)- capsular antigen- antiphagocytic 2. V & W antigens (mech unknown!) fuel Injection VW bug reservoir = rats....also squirrels/prairies dogs in SW U.S. vector = fleas invade skin --> reproduce intracellularly --> spread to LN's esp inguinal --> swell, painful (not always though); fever, h/a....invade blood, other organs hemorrhage under skin --> looks blackish --> "black death" tx- gentamicin "boubon"means "groin" |

pt camping in arizona/new mexico with fever, think........
|
....worry about yersinia pestis!
also tularemia |
|
|
Francisella tularensis is very similar to......
|
Bubonic plague (Yersinia pestis)
|
|
|
francisella tularensis
- labs - diseases caused - transmission - closely resembles what? |
gram neg rod
rabbits, ticks, deerflies, other animals (Francis Rabbit in Tulips with Ticks and Deerflies) extremely virulent!! very similar to bubonic plague! invades anywhere in body Tularemia 1. Ulceroglandular- hole in skin w/ black base at site of contact (how to distinguish from plague) --> LNs swell --> spreads to other organs (mortality ~5%--much less than plague) 2. Pneumonic- pneumonia 3. Oculoglandular (eyes) 4. Typhoidal (GI tract) EXTREMELY virulent! labs do not even cx it! just do skin test like PPD and titers! |
|
|
Brucella
- labs - diseases - transmission -dx |
gram neg rod
various spp (ie brucella melitensis, abortus, suis, canis) zoonotic: - animal meat (beef, cow, goat, pigs) - unpasteurized diary penetrates anywhere --> fever, constitutional sx UNDULANT fever! (peaks in evening, returns to normal by morning).....may last months to years! dx- culture, ab's, skin test UNpasteurized dairy --> UNdulant fever |
|
|
undulant fever
|
Brucella spp
- meat/animals - UNpasteurized airy |
