    • Causes hospital acquired infections.
    • Treated with Bactrim.

    Burkholderia

    • Causes glanders.
    • Can be transmitted from animals to humans.

    Acinetobacter

    • An aerobic bacteria that does not ferment glucose or lactose.
    • On gram stain, it appears as short rods.
    • Found widely in soil and water.
    • A frequent cause of nosocomial infections.
    • Causes pneumonias, bacteremias, and wound infections.
    • Highly resistant.
    • Can be treated with colistin.

    Stenotrophomonas Maltophilia

    • A bacteria that produces a lavender green or gray colony in the lab
    • Does not produce an enzyme called oxidase
    • Can use glucose and maltose for energy, but not lactose
    • Commonly infects people in the hospital setting
    • The preferred treatment is Bactrim

    Burkholderia

    • A type of bacteria that can cause a disease called glanders
    • Can be transmitted from animals to humans
