An instructor is reviewing Salmonella infections with her class. Which of the following comments indicates that the student needs further review on Salmonella?
"Salmonella is a bacterial infection."
"Salmonella symptoms include headaches, abdominal pain, diarrhea, nausea, vomiting, and fever."
"Salmonella may be spread by spores that form once contaminated blood is exposed to the air."
"Salmonella has a 48-hour incubation period."
The Correct Answer is C
A. "Salmonella is a bacterial infection." Salmonella is a gram-negative bacterium that causes foodborne illness.
B. "Salmonella symptoms include headaches, abdominal pain, diarrhea, nausea, vomiting, and fever." These are common symptoms of Salmonella infection, particularly gastroenteritis.
C. "Salmonella may be spread by spores that form once contaminated blood is exposed to the air." Salmonella is a bacterial infection that spreads primarily through contaminated food, water, or direct contact with infected animals. It does not form spores, and exposure to air does not play a role in its transmission.
D. "Salmonella has a 48-hour incubation period." While the incubation period can range from 6 to 72 hours, 48 hours falls within the expected time frame.
