Listeriosis in animals

Listeriosis in farm animals is important economically in Europe, North America, Australia and New Zealand.

[4] The most obvious signs for the veterinarians are neurological, especially lateral deviation of the neck and head, opisthotonus or emprosthotonus.

Other signs comprises compulsive movements of the lips, facial and masticatory muscles, with food staying in mouth.

In cattle, the most common sign is encephalitis, with fever, blindness, pressing against fixed objects, dullness, facial paralysis and circling.

Listeriosis in animals can sometimes be cured with antibiotics (tetracyclines and benzyl penicillin) when diagnosed early.
