What types of doctors treat listeriosis?
Although primary-care physicians can treat listeriosis, other specialists may be involved, especially if the illness is serious. Other specialists such as infectious-disease, critical-care, and OB/GYN physicians, especially if a woman is pregnant, are likely to be consulted. In those patients who are immunosuppressed, physicians that are treating the cause of the immunosuppression should also be consulted.
How do health care professionals diagnose listeriosis?
Preliminary diagnosis is usually based on the patient's clinical history and physical exam, especially after the patient gives a history of likely exposure to a contaminated food source during a Listeria outbreak. Without this information, the diagnosis is difficult to sort out from many other diseases; this situation may result in a delay of treatment as the physician may do other tests to rule out other diseases such as salmonellosis, shigellosis, botulism and E. coli infections. Definitive diagnosis of listeriosis is by culturing Listeria monocytogenes bacteria from the patient's blood, cerebrospinal fluid, or amniotic fluid, usually on a medium that is selective for Listeria (for example, RAPID'L mono agar). Currently, no reliable tests are available to detect the bacteria in the stool; also, there are no reliable serological tests available (blood tests that can identify specific proteins associated with the bacteria or antibodies to the bacteria) according to the CDC.
