    Acute HIV

    How to Recognize and Treat Acute HIV Syndrome - 8/1999 - American Academy of Family Physicians



    Cat-scratch disease

    Ehrlichiosis (Human Granulocytic and Monocytic Ehrlichiosis)

    Looks like flu without cough, but hepatitis, leukopenia, thrombocytopenia anomaly. A "mild" RMSF without the rash. 10-30% have macular red rash of trunk.

    Hepatitis A

    Hepatitis B

    Hepatitis C

    Herpes Labialis






    Legionnaire's Disease



    Lyme Disease

    (PS - jf personal opinion 2/15/2003: HIV infection cannot propagate in a world where smallpox is endemic. In a world of endemic HIV is a rapidly lethal disease of low contagiousness -- such a disease cannot become epidemic. HIV emerged from African in the 1960s, after smallpox had become rare in Africa. In a sense, the prevention of smallpox enabled AIDS.)

    Streptococci explicated

    Beta Hemolytic

    (Lyse red blood cells, on blood agar. Subdivided into Lancefield groups based upon polysaccharide antigens)

    Group A representative species: Strep Pyogenes

    Group B: representative species: S. agalactiae

    Group D

    1. enterococcus: S. fecalis (resistant to most antibiotics except ampicillin/amoxicillin)
    2. nonenterococcis: S. bovis: (a) subacute bacterial endocarditis

    Alpha Hemolytic

    Partial lysis of RBC on blood agar plates. Just S. viridans: SBE, caries

    Non Hemolytic (gamma)

    Anaerobic are pathogens: peptostreptococcus: abscesses, gangrene, necrotizing fasciitis, peritonsillar abscess

    S. Pneumoniae, Pneumococcus

    Very different from other streptococci. S. pneumoniae does not producte any important toxins, all will lyse RBCs (alpha hemolysis under aerobic conditions, beta hemolysis under anaerobic conditions). Has a special capsule which messes up neutrophils, that’s why its so lethal. There are at least 84 different immunologic capsule subtypes, with two different nomenclatures. Pneumonia and:
