*Outbreaks of listeriosis caused by ''L. monocytogenes'' seasonal and linked to silage feeding
*Replicates in poor quality silage where the pH excedes 5.5
*Animals highly susceptible during pregnancy due to lowered cell-mediated immunity
*Neural listeriosis:
**Incubation period 14-40 days
**Meningoencephalitis
**Dullness, circling, head tilt, facial paralysis, drool saliva, droop of eyelid and ear
**Exposure keratitis
**Fever during early stages
**Recumbency and death within a few days in sheep and goats
**Abortion up to 12 days after infection in cattle; usually recover but may get septicaemia
*Septicaemic listeriosis:
**Incubation period 2-3 days
**Lambs and occasionally pregnant sheep
**Occurs in newborn piglets, foals, poultry, adult sheep
*Keratoconjunctivitis in cattle and sheep - direct contact with silage via eye
*Pneumonia, myocarditis, enodcarditis
*Zoonosis - consumption of contaminated unpasteurised milk; memingitis and meningoencephalitis; abortion
