Capitolo 19, Problema 1
Which of the following bacteria causes a common type of food poisoning?
a. Streptococcus sanguis
b. Clostridium tetani
c. Staphylococcus aureus
d. Streptococcus pyogenes
Guida verificata passo dopo passo1
Step 1: Understand the question is asking which bacterium is commonly associated with food poisoning, a condition caused by ingestion of toxins or bacteria-contaminated food.
Step 2: Review the characteristics of each bacterium listed: Streptococcus sanguis is primarily associated with oral flora and dental plaque, not food poisoning.
Step 3: Clostridium tetani is known for causing tetanus, a neurological disease, and is not typically linked to food poisoning.
Step 4: Staphylococcus aureus produces enterotoxins that can contaminate food and cause rapid-onset food poisoning symptoms, making it a common cause of food poisoning.
Step 5: Streptococcus pyogenes is mainly responsible for infections like strep throat and skin infections, not food poisoning.
