Correctly match the organism (genus species) with the disease it causes
Why Malaria is hard to prevent with vaccination
Antibody does not have much time to act (cell lysis and reinfection is fast) 2. Red blood cells can not present antigen to signal they are infected 3. T cells can not recognize them and kill infected cells.
Bartonella henselae
Causes: Cat scratch disease Results: Puss at the sites weeks after initial injury, swollen draining lymph node, difficulty to culture, so serology or PCR are used to diagnose
Rickettsia prowazekii
Causes: Epidemic Typhus Results: spread by body lice: rash on trunk
Clostridium perfringens
Causes: Gas Gangrene Results: Anaerobic bacteria that can grow in wounds that have lost blood supply
Borrelia burgdorferi
Causes: Lyme Results: Tic borne; bulls eye rash, chronic stage inflammation can cause arthritis
Plasmodium (apicomplexan protist species of Plasmodium)
Causes: Malaria Results: nearly 1/2 million deaths per year, symptoms: start with malaise, abrupt chills, and fever, rapid and faint pulse, polyuria, headache, myalgia, nausea, and vomiting. After 2 to 6 hrs of these symptoms, the fecer falls, and profuse sweating occurs for 2 to 3 hours, followed by extreme fatigue. Symptoms occue b/c of synchornized rupture from blood cells
Yersina pestis
Causes: Plague Results: -bubonic: starts at skin, bubos in draining lymph SWOLLEN LYMPH -pneumonic: can be spread person to person -septicemic: DIC causes ischemia and necrosis in extremities (50% mortality) BLACK TOES
Rickettsia rickettsia
Causes: Rocky Mountain Spotted Fever Results: Tic borne, petechia rash starting at extremities. Begins at the hands and writs and then spreads to the trunk.
Human Herpes Virus
Infectious Mononucleosis
Plasmodium pathogen itself
Malaria, has devlopmental stages in both mosquito and human hosts, spread to humans in bit of mosquito, is an intracellular parasite
Route of transmission Malaria
Mosquito takes a blood meal and injects Plasmodium, Liver cell is infected, Plasmodium multiples, Plasmodium enters the blood, Gametes produced by meiosis, Microgamete fertilizes macrogamete, Zygote, Mitosis, Parasite differentiates and enters saliva.
