Final answer:
Salmonella bacteremia commonly affects individuals with weak immune systems and those with certain preexisting conditions. High-risk groups also include older adults and young children.
Step-by-step explanation:
Salmonella bacteremia is most commonly seen in patients who have compromised immune systems, such as individuals with preexisting medical conditions like congestive heart failure, diabetes, or high blood pressure.
Other high-risk groups include pregnant women, young children, older adults, and people with weakened immune systems due to conditions such as liver disease, kidney disease, or HIV/AIDS, as well as those receiving treatments like chemotherapy or radiation.
Salmonella infection, also known as salmonellosis, is caused by ingestion of food contaminated with the bacterium, and it is especially prevalent in foods like undercooked eggs and raw poultry.
