A foodborne ailment is listeriosis. Listeriosis is caused by the bacteria Listeria monocytogenes. Natural environments frequently include Listeria monocytogenes, particularly in the soil, groundwater, decaying plants, and animal feces (poop). L. monocytogenes and listeria are other names for listeriosis.
Eating contaminated food is how most individuals develop listeriosis. The duration between when you become infected with listeriosis and when you first exhibit symptoms (the incubation period) varies. Although it often takes one to two weeks, it could take as little as a few days or as much as three months.

Your doctor will normally take a blood sample for testing if they have any reason to believe you might have listeriosis. The doctor might also examine your spinal fluid if you exhibit meningitis' typical symptoms, such as headache, stiff neck, disorientation, or lethargy. The doctor may also take samples from the placenta in cases where pregnant women have a fever and other indications of listeriosis and deliver.
Your doctor will develop an appropriate treatment plan for you if the results show that you have listeria infection, though some patients with minor symptoms might not even require therapy.
The severity of your symptoms and health state will determine how you are treated for listeriosis.

Your doctor will prescribe antibiotics if your listeriosis is more severe. These medicines either destroy or retard the growth of bacteria. Ampicillin and trimethoprim-sulfamethoxazole (Bactrim), two popular antibiotics, are used to treat listeriosis.
You'll probably need to stay in the hospital and receive intravenous (IV) medicine if you have invasive listeriosis. The medical staff can keep an eye out for issues while administering antibiotics intravenously to help treat the illness.
If you have listeriosis while pregnant, your doctor will advise you to start taking medication. They'll also keep an eye out for symptoms of distress in your infant. Antibiotics are given to newborn infants with infections as soon as they are born.
