infectious bovine keratoconjunctivitis

(redirected from Morexella)


Veterinary medicine
A highly contagious pinkeye-like keratoconjunctivitis that affects cattle, caused by Moraxella bovis, an obligate intracellular, gram-negative aerobic bacillus, which is spread by direct contact or via the common fly.
Clinical findings
Purulent conjunctivitis, oedema, corneal opacity and ulceration, loss of appetite, weight loss.
Long-acting antibiotics—e.g., tetracycline.

(in-fek'shŭs bō'vīn ker'ă-tō-kŏn-jŭngk'ti-vī'tis)

Synonym(s): pinkeye (2) .


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 hematopoietic necrosis of fish
important rhabdoviral infection of Onchorhyncus spp. especially steelhead (anadromous rainbow trout).
infectious hypodermal and hemopoietic necrosis
parvovirus infection causing high mortalities in juvenile Penaeus stylirostris and runt deformity syndrome in P. vanname.
infectious labial dermatitis
see contagious ecthyma.
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.
infectious pancreatic necrosis of fish
a disease of salmonids caused by a group of related birnaviruses. It is characterized by hemorrhages and anemia, and spiral swimming and abdominal distention in fry.

infectious porcine polyarthritis

infectious salmon anemia
severe disease of Atlantic salmon, reported only, to date, from Norway; characterized by liver necrosis caused by an unidentified virus.
infectious serositis
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.
infectious stunting syndrome
caused by an enterolike virus this disease causes serious losses in the broiler industry; it is characterized by severe growth depression commencing at 1 week of age or earlier. Called also helicopter disease.

They found that Haemophilus influenzae colonization was competitively associated with Streptococcus pneumoniae and Morexella catarrhalis colonization in children with AOM but was not associated with S.
This condition may also be caused by infectious agents like Morexella bovis and sometimes due to allergy, less tear production which are referred to as Infectious bovine Keratoconjunctivitis, allergic keratoconjunctivitis and Keratoconjunctivitis sicca respectively.
