Symptoms Of Listeriosis (Listeria)

When Infection Spreads To The Brain

So, what happens when listeriosis spreads to the brain? This can result in some serious complications, including cerebral abscesses, which is pus that collects within the brain; cranial nerve palsies, which are tremors and paralysis; and meningitis, which is inflammation of the membranes surrounding the spinal cord and brain. It can also include encephalitis, which is inflammation of the brain itself; and meningoencephalitis, which is inflammation of both the membranes around the spinal cord and brain and inside of the brain. When a listeria infection spreads to the brain, it can be harder to treat and will likely be more long-lasting than the more common, less-threatening symptoms.

Fever

Like most infections, listeriosis typically presents with fever. Healthy individuals will rarely become ill from listeria, but those with compromised immune systems and newborns may exhibit a fever and other symptoms. The fever may start just a few days following the consumption of the contaminated food, but it's also possible up to a month will pass before individuals start exhibiting a fever or other infection symptoms. Fevers occur when the immune system raises the body's temperature as it fights the infection. A high fever is any fever greater than 103 degrees Fahrenheit. If patients experience a high fever, they may need emergency medical treatment to combat the listeria infection and prevent potential organ damage.
