Listerial sepsis is a serious bacterial infection caused by Listeria monocytogenes. This type of sepsis is relatively rare, but it can be life-threatening, particularly for people with weakened immune systems. Listeria monocytogenes is a type of bacteria that is commonly found in soil, water, and some animals. It can also be found in some types of food, including unpasteurized dairy products and processed meats.
People who are at highest risk for listerial sepsis include pregnant women, newborns, older adults, and people with weakened immune systems, such as those with HIV/AIDS or undergoing chemotherapy. Symptoms of listerial sepsis may include fever, chills, muscle aches, and diarrhea. In some cases, the infection can spread to the bloodstream, causing sepsis.
