  1. Game Plan Lecture Cardio/ lymphatic systems Bacterial diseases Viral diseases Protozoa diseases Helminthic diseases Lab Major Unknown Water microbiology

  2. Circulatory system Components: • Heart • Blood vessels • Arteries • Veins • Capillaries • Microbes and toxins persisting in blood= septicemia • Systemic inflammatory response syndrome= sepsis

  3. The lymphatic system Components: • Lymph capillaries • Collects plasma/ interstitial fluid/ microbes from tissues • Lymphatics lead to lymph nodes • Macrophage, T and B cells reside here • Swollen lymph nodes are buboes

  4. Lymphangitis and septicemia/ sepsis

  5. Infective endocarditis

  6. Infective subacute endocarditis Symptoms Fever Heart murmur Fibrin platelet vegetations

  7. Bacillus anthracis- anthrax

  8. Yersinia pestis- plague Types Bubonic plague Septicemic plague Pneumonic plague

  9. Human US Plague distribution

  10. World-wide plague distribution

  11. Rickettsia rickettsii- Rocky Mountain spotted fever Symptoms Typhus infects endothelial cells of vascular system Rash similar to measles, but also on hands and feet Fever and headache Kidney and heart failure (3%)

  12. Viral hemorrhagic fevers

  13. Epstein-Barr Virus (herpes virus 4) EB Viral diseases Burkitt’s lymphoma Infectious mononucleosis Possibly: MS Hodgkin’s disease Nasopharyngeal cancer

  14. Leishmaniasis

  15. Leishmaniasis

  16. Malaria

  17. Wuchereria bancrofti- filariasis or elephantiasis Characteristics Round worm transmitted by mosquito Peripheral BV during night, deep vessels during day Blockage of lymph vessels leads to elephantiasis

  18. HIV Figure 19.15
