Question

Two microorganisms that produce toxins in food that can cause symptoms after the food is consumed even without infection by the microorganisms are?

A) Staphylococcus aureus and Clostridium botulinum
B) Streptococcus pyogenes and Clostridium botulinum
C) Staphylococcus aureus and Streptococcus pyogenes
D) Escherichia coli and Shigella dysenteriae
E) Vibrio cholera and Escherichia coli

Answer 1

Staphylococcus aureus and Clostridium botulinum are two microorganisms that produce toxins in food that can cause symptoms even without infection. Staphylococcus aureus produces enterotoxins that cause vomiting and diarrhea, while Clostridium botulinum produces botulinum neurotoxin that leads to flaccid paralysis.

Step-by-step explanation:

The two microorganisms that produce toxins in food that can cause symptoms after the food is consumed even without infection by the microorganisms are Staphylococcus aureus and Clostridium botulinum.

Staphylococcus aureus produces enterotoxins that are resistant to low pH and heat, causing vomiting and diarrhea. Clostridium botulinum produces botulinum neurotoxin, which blocks the release of acetylcholine, leading to flaccid paralysis. These toxins can cause foodborne illness even without a bacterial infection.
