Listeriosis

Listeriosis, also known as Listeriosis, is an infection caused by Listeria monocytogenes. The clinical manifestations are mainly meningitis, septic granuloma, and lymphadenopathy. The disease is spread all over the world and is a zoonotic infectious disease. Human infections have a tendency to increase, especially newborns, the elderly, pregnant women and those with low immune function are more susceptible. Pathogens in a sick pregnant woman can infect the fetus or newborn through the placenta or birth canal. The disease is generally sporadic and occasional pandemics can occur in infants. Sources of infection are mainly storage hosts, patients, and carriers. The peak of the onset is in the summer and is mainly transmitted through inhalation, ingestion or direct contact with pollutants, and it can also be transmitted directly from person to person. The mortality rate of this disease is relatively high. For example, the mortality rate of meningitis patients after antibacterial treatment is still 30%.
