Determine the Syndrome of Listeriosis

Syndrome: Listeriosis in humans is not characterized by a unique set of symptoms since the course of the disease depends upon the state of the host. Non-pregnant healthy individuals who are not immunosuppressed are highly resistant to infection by L. monocytogenes. When susceptible adults contract the disease, meningitis and sepsis are the most commonly recognized symptoms. Pregnant females who contract the disease may not present any symptoms, but when they do, they are  typically mild and influenza-like. Abortion, premature birth or stillbirth is often the consequence of listeriosis in pregnant females. When a newborn is  infected at the time of delivery, listeriosis symptoms typically are those of meningitis and they begin at 1 to     4 weeks after birth, although  a four week incubation has been recorded. The usual incubation time in adults ranges from one to several weeks.
