Avoid the use of mutilations as standard production practices. Each year, particularly during late fall and winter, we see cases of acute listeriosis in sheep, goats, camelids, and cattle. Close grazing with soil ingestion may also be a cause. Forage and grazing being the main source of nutrients for ruminants, and continuously available to non-ruminants. Sheep and goats are most susceptible to Listeria infections and are overcome by an acute disease with death occurring 4-48 hours after the onset of clinical signs. Circling sheep and rapid deaths are what most farmers think of when mentioning Listeria. listeriosis is mainly confined to sheep. Registered in England No. Affected sheep should only be considered for treatment if they are in the early stages of the disease; otherwise, they will have to be humanely killed. If possible, feeding sheep silage should be avoided. It affects all ages and both sexes, sometimes as an epidemic in feedlot cattle or sheep. Listeriosis is an infectious but not contagious disease caused by the bacterium Listeria monocytogenes, far more common in domestics animals (domestic mammals and poultry), especially ruminants, than in human beings. Sheep are particularly sensitive to the bacteria. Exposure to air should also be avoided (Low and Renton, 1985). Outbreaks of this disease have generally involved the ingestion … 6, 33 Mastitis and keratoconjunctivitis have also been recorded. Vat No GB: 90 1976 91, Molecare Veterinary Services Ltd, Registered Office: Exmoor House, Lime Way, Pathfields Business Park, South Molton, Devon, EX36 3LH.

Treatment should only be instigated if the ewe is not recumbent. As shown above, there are plenty of other diseases which cause nervous signs in sheep, all with very different treatments which usually require prompt intervention. Listeriosis is caused by the bacterium Listeria monocytogenes and is commonly seen in cooler climates. Although Listeria can survive for up to three months in stored  livestock manure (Nicholson et al., 2005) and following application on land, the bacteria do not survive when high temperatures are achieved in manure storage  (Hutchinson et al., 2004). She died shortly after examination. Each year, particularly during late fall and winter, we see cases of acute listeriosis in sheep, goats, camelids, and cattle. Whilst this is true, the disease presents itself in many different forms, not just circling, and an accurate prompt diagnosis is often key to saving affected sheep. In 55 of them the diagnosis was made on the basis of the typical signs, which included vestibular ataxia, circling, head tilt and unilateral cranial nerve deficits, but in 12 animals a definitive diagnosis was made only after postmortem examination. Listeriosis usually affects ruminants such as cattle (Figure 1), sheep and goats, and causes a range of clinical signs in these animals.

The prevalence of L. monocytogenes on ruminant farms is seasonal, and associated with farm management practices, animal health and hygiene and feedstuff quality and storage. Listeria monocytogenes is found in soil, feedstuffs and faeces. Improperly prepared silage having a pH value greater than 5.4 and silage which has become spoiled due to prolonged exposure to air (Clarkson and Faull, 1987; Low and Renton, 1985) will enable the organism to multiply. If possible, avoid feeding silage to sheep and certainly do not feed poor quality silage.

Listeriosis can be confirmed as the cause of death in sheep by examination of the brain Treatment Recovery of sheep from listeriosis depends on early detection of illness, together with prompt and aggressive antibiotic treatment prescribed by the vet.
