Identify the disease based on the following (select all that apply): It is a small, acid-fast rod
usually remaining asymptomatic for up to 20 years. It affects the skin, nerves, upper respiratory

While visiting his grandparents, a 10-year old child has green beans for dinner that were
harvested from his grandparents' garden and canned the previous year. Severe illness sets in
and the child is taken to the hospital. Botulism is suspected, but what form? (short answer) -
answer>>>Foodbourne botulism. The child is too old (> 6 months) to be considered and
wounds were not present. The green beans were likely improperly canned and under the low-
acidic, anaerobic conditions, bacterial growth was encouraged
, True or False: Although there is no cure for tetanus, it can be prevented through vaccination -

vaccination
Describe the symptoms and treatment regimen for someone infected with Clostridium
pefringens (short answer) - answer>>>Clostridium perfringens presents with muscle necrosis,
swelling of infected areas, fever, and intense gas production. Treatment entails removal of all
infected tissue, often resulting in amputation of the affected areas, in conjunction with heavy
antibiotic therpies
Why does the alpha toxin (perfringolysin) produced during an infection of gas gangrene cause
cell death? (short answer) - answer>>>The toxin perforates the membrane. It forms pores in
the plasma membrane of host cells resulting in uncontrolled ion fluxes and eventually cell lysis
and death
You develop a fever, chills, and pneumonia after recently using a warm midst vaporizer in an
attempt to open your sinuses. What bacterial disease would a doctor suspect is causing your
symptoms? Would the doctor suspect you contracted it from touching (potentially)
contaminated doorknobs? (short answer) - answer>>>Legionnaires. No- legionella cannot be
