Septicemia |
Human (blood)
-toxins/ pathogens in blood -lymphagitis –inflamed lymph vessels |
|
|
Reservoir? Virulence factors? Symptoms?
Sepsis |
Human
Infection induce inflammatory response -systemic inflammatory response syndrome (SIRS) -lymphagitis –inflamed lymph vessels -septic shock -low blood pressure (organ failure) Symp. -Increase respiratory rate -high WBCs -Trachycardia -fever |
|
|
Reservoir? Virulence factors? Symptoms?
Endocarditis & Pericarditis |
Human
- Painful, red palms Heart impairment -inflammation of lines the heart muscle itself and covers the valves |
|
|
Reservoir? Virulence factors? Symptoms?
Anthrax |
-soil
-large grazing animals (Zoonotic) -polypeptide capsule -exotoxins -endospore-forming -go into vegetative host -sporulate in feces or in carcasses of dead animals *pulmonary= 99% fatal if untreated: -releases exotoxins -cause CV shock through toxemia *gastrointestinal=50% mortality Fever, weakness, heart murmur, damage to heart valves -inflammation of the sac around the heart |
|
|
Reservoir? Virulence factors? Symptoms?
Gas gangrene (myonecrosis) |
Human (intestinal tract)
-necrotic (damage) condition w/ a release of gases (CO2 &H) -ferment carbs in tissue -produce gases(CO2 & H) -collagenase-degrade collagen and proteinaceous tissue -exotoxins -lead to toxemia into systemic -ischemia (wound becomes anaerobic. -ischemia leads to necrosis -black, dying tissue -poor circulation |
|
|
Reservoir? Virulence factors? Symptoms?
Plague |
Animals:
-rats, ground squirrels -prairie dog -ability to survive & multiply inside phagocytic cells Bubonic plague:-bacterial growth in blood and lymph *Septicemia plaque: septic shock *Pneumonic plague: bacteria in the lungs *100% fatal if untreated -enlarged lymph nodes -septic shock -nodes swells to form bubos -lung infection |
|
|
Reservoir? Virulence factors? Symptoms?
Lyme disease |
Deer & mice
-spirochete 1st sym.-Bull’s-eye rash 2nd sym.-irregular heartbeat, encephalitis 3rd sym.-Arthritis |

|
|
Reservoir? Virulence factors? Symptoms?
Toxoplasmosis |
Animal
-cats, mice,cow Oocysts formed sexually in cats intestine. -sporoaoites inside await intermediate hosts(mice & livestock) -sporoaoites invade host cells, reproduce, and rupture cells resulting in inflammation -tissue cysts or tachyzoites are infective -mild disease -infection during pregnancy can damage the fetus (stillbirth, w/ severe brain damage/ vision problems |
|
|
Reservoir? Virulence factors? Symptoms?
Sub-acute endocarditis |
Human (nasopharyxn)
Fever, trap in clots multiply -w/n lesions multiply protest from phagocytes and antibodies Painful, red palms Heart impairment -inflammation of lines the heart muscle itself and covers the valves |
|
|
Reservoir? Virulence factors? Symptoms?
Acute bacterial endocarditis (pericarditis) |
Human (nasopharyxn)
Bacterial endocarditis Fever, weakness, heart murmur, damage to heart valves -inflammation of the sac around the heart |
|
|
Reservoir? Virulence factors? Symptoms?
Rheumatic fever |
-autoimmune compliatoins
-immune rxn strep. M protein damages the valves -arthritis -fever -damage to heart valves (inflammation of the heart valves) -nodules at swollen joints |
|
|
Reservoir? Virulence factors? Symptoms?
Tularemia |
Animal
(rabbit fever) -anti-phagocytic can multiply in macro. -w/o treatment lead to sepsis -penetration of skin at a minor abrasion, creates an ulcer at the site -lymph nodes enlarge (pus) -sepsis -infection of multiple organs |
