    • Streptococci
    • Streptococcus pneumoniae
    • Staphylococcus & Streptococcus: Learning Outcomes

    Included Quiz Questions

    1. These type of bacteria make a penicillin binding protein 2a, which supports penicillin resistance.
    2. These type of bacteria can be treated with higher doses of antibiotics if paired with exfoliative toxin A.
    3. The beta-lactamases in MRSA encode for better reception of the penicillin type antibiotic.
    4. MRSA stands for 'Methicillin-Resistant Strep Aureus'
    5. It is not a very serious infection.
    1. Rheumatic Fever
    2. Scalded Skin Syndrome
    3. Toxic Shock Syndrome
    4. An increase in the TSST-1 toxin.
    5. Food poisioning
    1. They cannot produce the necessary proteases to digest proteins in the host which would normally restrict the spread of the bacteria.
    2. They produce an enzyme that converts plasminogen to plasmin
    3. They have multiple ways to avoid destruction by macrophage-like cells.
    4. They produce two different kinds of streptolysins.
    5. They move systemically through the body.
    1. Permanent hoarseness
    2. Non-suppurative sequelae
    3. Acute rheumatic fever
    4. Inflammation of heart tissue
    5. Polyarthritis
    1. If you are an adult and you were never immunized, you should get the pneumococcal polysaccharide vaccine.
    2. There is one vaccine that can be given to everyone to prevent contracting pneumococcal pneumonia.
    3. There are four different vaccines for children, adults, the elderly, and the immunocompromised, each catering to the particular strains most likely to infect the subgroup.
    4. The vaccines protect against all known strains of pneumococcal pneumoniae.
    5. If the vaccine is given to a child, they still need to receive a booster as an adult to remain protected.
    1. Both streptococci and staphylococci can be spread by asymptomatic carriers.
    2. Both streptococci and staphylococci can result in Rheumatic Fever.
    3. They both can cause Toxic Shock Syndrome.
    4. Both streptococci and staphylococci have gram-negative, grape-like structures.
    5. They both can be easily treated with antibiotics.
