Normal Microflora of Cardiovascular and Lymphatic systems
NONE
Transient Bacteremia: What you hope to find
- hobo: original transient AKA bacteria that travel through cardiovascular and lymphatic
system
- Transient because it comes and goes, if not you’re dead
Septicemia AKA lymphangitis: food poisoning; red line of inflammation that moves from site of
injury down or out
- can lead to SEPTIC SHOCK
- Sx: Fever, low BP (blood vessels begin to collapse which leads to necrosis and
gangrene), red streaks
- Mostly nosocomial
- 50-70% death rate
- Onset: 24 hours
- Diagnose: Blood culture
- Trt: Elevate BP so you can give antibiotics (oral or IV)
Bacterial endocarditis: Bacteria start to inflame the heart, heart lining, or valves.
- Occurs in 45 yrs and up
- Acute cases exist: 33% and kills people within days, ⅔ are subacute ; people experience
fever, malaise, and heart murmur
- Heart valves get damaged by bacterial vegetation
Pericarditis: inflammation of lining around heart
- squeezes heart muscle
- 40% of cases are staphylococcus aureus, untreated mortality is 100%
- With treatment: 20-40% mortality rate
Streptococcus pneumoniae: Immunocompromised patients
Streptococcus pyogenes: Group A streptococcus
- Doctor Semmelweis
- Has hemolysins for splitting RBCs
- Described by Rebecca Lancefield
- Born 1895 died 1981, she was the president of the American Society of
Microbiology
- Member of National Academy of Sciences and professor at Rockefeller
University
- Classified 50 types of bacteria
- Focus was on bacteria that were pathogenic and causing infectious disease
- Common as repurial (?) fever
- Fever and chills, site is in pelvis though, bloody discharge
- Trt: Antibiotics and might have to use penicillin
- Takes weeks to recover
