Bacterial Deseases of the Blood
| Question | Answer |
|---|---|
| Bacteremia | bacteria in the blood |
| bubo | bobonic comes from this--intensley painful, swollen lymph node packed with immune cells and dying tissue |
| Bobonic plague | Yersinia pestis, gram-neg rods, first phase bubo--2nd phase bacteria spread through bloodstream- dark purple to black hemorrhages occur--black death-- |
| Endemic typhus | Richettsia typhi prevalent in rodent populations and uncommon to humans |
| Fungemia | fungi in the blood |
| Lyme disease | spirochete bacteria, transmitted by tecks--Borrelia burgdorferi--transmitted by Ixodes tick--mice primary carrier--3 phases-red rash, red ring slowly expands with red spot remaining at bite site--bulls eye rash--may be 15" in diameter--enters bloodstream- |
| Pneumonic plague | extrememly contagious--100% mortality if not tx early--spread via resp aerosols |
| Q fever | caused by Coxiella burnetii--gram-neg coccobacilli, obligate intracellular bacteria, transmitted by insects or fluids--acquired from aerosole/contaminated animal fluids(milk)--flu-like sx may progress to headache fever, pneumonia, and endocarditis |
| Rocky mountain spotted fever | rickettsia rickettsii--gram-neg coccobacilli, obligate intracellular bacteria, transmitted by ticks--begins with headache, muscle/joint pain, fever--pink rash on hands/soles of feet appears in about 1 week, spreads to body--hemorrhagic--leads shock/death |
| Septic shock | agent/toxins cause infected person's blood pressure drop below level required for normal organ functioning |
| Septicemia | agent/toxins in blood cause disease--normally involves active growth of microbes in bloodstream |
| Systemic diseases | diseases spread throughout the body |
| Toxic shock syndrome (TSS) | enterotoxin produced by S. aureus--bacteria grow in and around tampons--enterotoxin cross into bloodstream and affect neural centers cause confusion and shock--ABT necessary--gram-pos--Staphylococci, Aureus |
| Tularemia | gram-neg rods---known as rabbit fever--Francisella tularensis--common via mucous membranes who skin rabbits--ulcer at bite location, swollen lymph nodes, fever, chills, aches,--majority need no tx |
| Typhus | Rickettsia prowazekii--gram-neg coccobacilli, obligate intracellular bacteria, transmitted by lice--bathing and physical removal of lice important measures in disease prevention |
| Viremia | Viruses in the blood |
