''Listeria monocytogenes'' is one of the six species belonging to the genus [[Listeria species - Overview|''Listeria'']]. It is gram positive bacteria.
Outbreaks of [[Listeriosis|listeriosis]] in the human population are caused by ''L. monocytogenes''. The outbreaks are seasonal and linked to silage feeding. In most cases, the symptoms are those of a mild gastroenteritis or gripe. However, people who belong to the high - risk groups (elderly, infants, pregnant women or people with immunosuppression) might develop more serious symptoms (invasive disease) caused by meningoencephalitis, septicemia, miscarriage and mortality rate of approximately 30%.
''Listeria monocytogenes'' replicates in poor quality silage, where the pH exceeds 5.5.
Listeria monocytogenes replicates in poor quality silage, where the pH excedes 5.5.
Animals are highly susceptible during pregnancy due to lowered cell-mediated immunity.
