infectious bulbar paralysis

Etymology: L, inficere, to stain, bulbus, swollen root; Gk, paralyein, to be palsied
a herpesvirus disease of animals (swine, cattle, dogs, cats, and rats) that may cause a mild pruritus when transmitted to humans. Also called pseudorabies.


pertaining to a bulb; pertaining to or involving the medulla oblongata, as bulbar paralysis.

infectious bulbar necrosis
one of the several forms taken by foot abscess in sheep. See also foot abscess.
infectious bulbar paralysis
bulbar paralysis
originates from the medulla oblongata. The pyramidal and extrapyramidal tracts pass from the midbrain through the medulla and are susceptible to damage by agents that operate in the area. Paralysis of this type has the characteristics of an upper motor lesion with muscle tone and local tendon reflexes retained.


caused by or capable of being communicated by infection.

infectious avian nephritis
caused by a picornavirus this disease of young chickens causes a transient unremarkable disease with lesions appearing in the kidney.
infectious bovine cervicovaginitis
thought to be due to a herpesvirus-4 infection, transmitted by coitus, causing sterility in a high percentage of cows and some bulls. Recorded only in South Africa. Called also epivag.
infectious bovine keratoconjunctivitis
the common infectious keratitis of cattle caused by Moraxella bovis with solar radiation, dust and face flies as contributing factors.. It occurs as outbreaks, characterized by ocular discharge, blepharospasm and pain. Underrunning of the conjunctiva leads to complications in a few cases. Called also pinkeye, blight, New Forest disease.
infectious bovine meningoencephalomyelitis
infectious bovine rhinotracheitis (IBR)
a highly infectious disease of cattle, particularly when crowded together as in feedlots, caused by bovine herpesvirus 1 and characterized by nasal discharge, rhinitis, tracheitis, conjunctivitis, fever and a short course unless complicated by other infections, particularly those leading to pneumonia. Less common forms of the disease include encephalitis in calves and a systemic infection in neonates, manifested by oral erosions and diarrhea. Infectious pustular vulvovaginitis is also caused by this virus. Called also rednose.

infectious laryngotracheitis (ILT)
a highly infectious disease of birds of all ages caused by avian herpesvirus 1 and characterized by a very rapid spread of respiratory distress, the signs including gasping, respiratory gurgling and rattling, and death often from asphyxiation because of massive pseudomembrane formation in the trachea. The mortality rate may be as high as 70%.
infectious necrotic hepatitis
an acute toxemia of cattle, sheep and pigs caused by Clostridium novyi which elaborates a toxin in necrotic infarcts in the liver. These infarcts are caused usually by larvae of Fasciola hepatica. Many affected animals are found dead. Clinical findings include severe depression, hypothermia and muffling of heart sounds. Called also black disease.

a septicemic disease of young ducks caused by Riemerellaanatipestifer and characterized by torticollis, head tremor, loss of balance and a high mortality rate.
infectious sinusitis
a contagious disease of turkeys caused by Mycoplasma gallisepticum. The same infection also causes chronic respiratory disease of chickens. The disease in turkeys is characterized by swelling of the infraorbital sinuses, which are filled with thick exudate. The course is chronic and the death rate low but there is severe loss of condition and damage to the respiratory tract.

loss or impairment of motor function in a part due to a lesion of the neural or muscular mechanism; also, by analogy, impairment of sensory function (sensory paralysis). Called also palsy. Motor paralysis may be expressed as flaccid, in the case of lower motor neuron lesion, or spastic, in the case of an upper motor neuron lesion.
