CARDIOVASCULAR SYSTEM
(3)
Heart
Blood vessels
Blood
microbiota of CV
CV system normally is sterile
LYMPHATIC SYSTEM
Lymph fluid
Lymphatics (vessels)
Lymph organs
microbiota of lymph system
Lymphatics system normally is sterile
BACTERIAL DISEASES OF THE CV AND LYMPH SYSTEMS(place marker)
many
Bacterial septicemia (sepsis)
GN or GP and why
Life threatening complications
Gram negatives especially implicated (any form of bacteria can cause septicemia, but gram negative are lipid based cell wall, which are much more resistant to the immune system and antibiotics
Endocarditis
CTR
Bacteria lodged in heart valves
May be fatal
Alpha streptococci especially implicated
Pericarditis
CR
Inflammation of the pericardium
Rapid progression
Streptococcus pyogenes especially implicated
Tularemia
CTR
Caused by Francisella tularensis (GNB)
Transmitted by rabbits and squirrels
Results in septicemia
Brucellosis (undulant fever)
CTR
Caused by Brucella sp. (GNB)
Associated with cattle, elk, bison
May spread to liver, spleen, bone marrow
May result in abortion of fetus
Anthrax
CTR
Caused by Bacillus anthracis (GPB)
Associated with grazing mammals
Cause skin lesions and pneumonia
Gangrene
CTR
Caused by Clostridium perfringens (GPB)
Soft tissue death due to ischemia
Creates anaerobic conditions
Bacteria enter wound and grow on nutrients from tissue
Toxins destroy adjacent tissue, as the bacteria feasts on dead tissue it grows and consumes tissue faster
Pasteurella multocida
TR
GNB often associated with dog and cat bites
May result in septicemia
Plague
CTR
When 100% fatal
Caused by Yersina pestis (GNB)
Highly fatal disease transmitted by fleas associated with rodents
Results in swollen lymph nodes and fever
If transmitted to lungs, nearly 100% fatal (pneumonic plague)
Lyme disease (originally found in lyme Connecticut)
CTR
Caused by Borrelia burgdorferi (spirochete)
Transmitted by ticks
May result in cardiac and neurologic conditions
Epidemic typhus
CTR
Caused by Rickettsia prowazekii (rickettsia)
Transmitted by body lice
Results in rash, fever, death
VIRAL DISEASES OF THE CV AND LYMPH SYSTEM (place Marker)

Caused by Epstein-Barr virus
Transmitted by oral secretions
Causes swollen lymph nodes, spleen and weakness
Yellow fever
caused by

symptoms
Caused by a flavivirus
Transmitted by mosquito
Results in fever, headache, jaundice
Ebola
caused by
transmitted
symptoms
Caused by a filovirus
Transmitted by contaminated blood
Results in massive bleeding, death

Leishmaniasis (hemoflagellate)
American trypanosomiasis (Chaga’s disease)
caused by
vector
results in
Caused by Trypanosoma cruzi
Transmitted by reduviid bug
Results in damage to heart and intestines
Weak, lethargic, chronic tiredness, then to a heart condition
Toxoplasmosis
cause
transmission
symptoms (adult and fetal)
Caused by Toxoplasma gondii
Transmitted by undercooked meat and cat excrement
Results in mild disease in adults
May result in severe fetal damage, causing retardation, or spontaneous abortion
Malaria
cause

Caused by Plasmodium sp.
Transmitted by mosquito (Anopheles sp.)
Results in fever, headache, anemia
Causes RBC to lyse
Leishmaniasis (hemoflagellate)
cause
vector
result
Caused by Leishmania sp.
Transmitted by sandfly
May result in disfiguring damage to mucus membrane and systemic disease of deep body organs
HELMINTH DISEASE OF THE CV AND LYMPH SYSTEMS (place marker)
Schistosomiasis
Schistosomiasis
cause
transmission
results
Caused by Schistosoma sp (fluke)
Penetrates skin from contaminated water
Results in inflammation and tissue damage in many organs
