    gram +
  3. Staphylococcus Aureus produces what enzyme?
    Coagulase-positive which clots plasma
  4. Staphylococcus epidermidis produces what enzyme?
    coagulase neg
  5. Pimples, boils, carbuncle, impetigo, and scalded skin syndrome are caused by what?
    Staphlococcus aureus skin infections
  6. Toxin shock syndrome, staphylococcal food poisoning, acute bacterial endocarditis, and subacute bacterial endocarditis is caused by what kind of strep?
    Staphylococcus aureus
  7. Lyse RBC's (streptolysin O) is
    Hemolysins, part of streptococcus pyogenes
  8. This helps organisms invade epithelium?
    Hyaluronidase, part of streptococcus pyogenes
  9. This break down blood clots (these have been used clinically as "clot buster" drugs to treat heart attack patients
    Streptokinase, part of streptococcus pyogenes
  10. these help organisms adhere to mucous membranes and prevents microbe from being phagocytized killed by WBC's?
    M proteins, part of streptococcus pyogenes
  11. These help them escape detection by immune system?
    Capsules made of hyaluronic acid,part of streptococcus pyogenes
  12. causing agent for strept throat?
    Streptococcus pyogenes, part of streptococcus pyogenes Group A streptococcal disease
  13. Erysipelas is an example of what?
    streptococcal skin infections
  14. Necrotizing fascitis is an example of what kind of infection?
    Invasive group A streptococcal infections caused by an exotoxin A, superantigen
  15. Strept throat and rheumatic fever are what kind of diseases?
    Group A Streptococcal diseases
  16. This disease is associated with hot tubs
    Psudomonas dermititis
  17. this disease is swimmers ear
    otitis externa
  18. This organism causes these skin infcetions, pseudomonas dermititis, ototis externa, post burn infections and opportunistic which are common in soil and water.
    pseudomonas aeruginosa
  19. This disease causes fever, headache and a stiff neck, it is followed by nausea and vomiting, it may progress to convulsions and coma and is diagnosed by gram stain and latex aggulation of CSF
    bacterial meningitis
  20. This meningitis is from vaginal colonization and the leading cause of neonatal sepsis, pna Puerperal sepsis and capsules. What type is it?
    group B strep or streptococcus agalactiae, group B hemolytic streptococci
  21. This meningitis is more contagious and is also called meningococcal meningitis, it is gram neg, has capsule and has endotoxins. 10% of people are carriers and it begins as a throat infection, non fading rash and has a vaccination recommended for college students
    Neisseria meningitis
  22. This meningitis occurs mostly in woung children carry it in normal throat flora, capsule antigen type B is most common, preventable by the HIB vaccine and also H. influenza type B causes pna,otitis media, and epiglttitis
    Haemophilus influenzae Meningitis
  23. This meningitis is also called pneumococcal meningitis, it is the leading cause of bacterial meningitis since hib vaccine, it is gram pos diplococci and has a capsule. &0% of people are carriers and is most common in children. Mortality is 30% in kids and 80% in elderly and have a vaccine for infants
    Streptococcus pneumoniae meningitis
  24. Pneumonia and otitis media are caused by
    streptococcal pneumoniae diseases
  25. These two are gram positive and produce disese because of exotoxins, they are endospore forming and are anaerobes.. remember its 2
    Clostridium and bacillus
  26. This causes tetanus, it growns in deep wounds, tetanospasmin is released from dead cells and blocks relaxation pathway in muscles, DTP is vaccination for this and treatment is with an immune globulin
    Clostridium tetani
  27. This organism agent is botulism, and get it by ingesting botulinal toxins that are extremely potent, botulinal toxin blocks the release of neurotransmitters causing flaccid paralysis and prevention in proper canning and treatment is antitoxin
    Clostridium botulinum
  28. botulism means?
  29. This type of botulism is the result from C. botulinum growing in the intestines and has been linked to raw honey
    infant botulism
  30. This botulism is the result from growth of C. botulinum in wounds
    Wound botulism
  31. This organism causes anthrax-cuteaneous, gastrointestinal or pulmonary, it is a capsule, it has exotoxins which are lethal(kill macrophages) it is found in soil, endospores can survive for years, disease found mainly in lifestock unless dug up and can be used as a biological weapon.
    Bacillus anthracis
  32. This causes a black scar and an endospore enter through a minor cut and can potentially enter the bloodstream with a 20% mortality rate w/out antibiotics
    cutaneous anthrax
  33. This is caused by ingesting undercooked,contaminated food and has a 50% mortality rate w/out antibiotics
    gastrointestinal anthrax
  34. This is caused by inhailing endospores and has a 100% mortality rate w/out antibiotics. WOW
    inhalational (pulmonary) anthrax
  35. This is normally found in sooil, large intestine, causes ischemia,necrosis,and gas gangrene
    clostridium perfringens
  36. loss of blood supply to tissue
  37. death of tissue is called
  38. this is growth of C. perfringens in necrotic tissue and the treatment is removal of necrotic tissue and or use of hyperbaric oxygen chamber
    Gas gangrene
  39. This bacteria causes food poisoning where endospores germinate and bacteria grow rapidly in fav conditions, the bacteria infect the gi tract and produce an enterotoxin that causes gastroenteritis 8-12hrs after ingestion. Name the organism
    clostridium perfringens
  40. The disease with arthropod vectors
    Borrelia burgdorferi
  41. Borrelia burgdorferi is?
    Lyme disease
  42. The vector for lyme disease is? The reservoir is?
  43. this disease causes a bulls eye rash and flu like symptoms in the first stage, second stage causes a irregular heartbeat, neurologic symptoms and the third phase can cause arthritis
    Lyme disease....borrelia burgdorferi
