*Outbreaks of listeriosis caused by ''L. moncytogenes'' seasonal and linked to silage feeding
+
[[Listeria monocytogenes]]
*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
