Upper respiratory tract disordersRHINITIS, CORYZA OR NASAL CATTARAH

• It is the inflammation of the m.m of the nose and usually involving the upper part of the trachea,

• it may be acute, chronic, croupous or follicular

• It is the most common cause of upper respiratory tract malfunction,

• Rhinitis results in exudation of neutrophils, macrophages, and fluids), or erosion and ulceration (or both) of the nasal mucosa.

• It may be caused by viral, bacterial, fungal, or parasitic agents, as well as by allergic reactions.

• Atrophy of the turbinates (eg, in atrophic rhinitis of pigs) removes a major filtration function and exposes the lungs to much heavier loads of dust and microorganisms.

• Obstruction of nasal cavity may occurred by tumors, granulomas, abscesses, or foreign bodies.

• Sinusitis can be a complication of upper respiratory infections or dehorning.

Rhinitis• Inhalation of irritant vapour as ammonia or

chlorides.

• Associting upper resp. syst. Diseases or pneumonias.

• In Cattle: Associate IBR ، R.P, MHC, MD/VD Adenovirus ، Rhinosporidiosis

• In Equine: Strangles, glanders, EV Arteritis, E. rhinooneumonitis

• In sheep: Blue tongue, Pox, Orf, Nasal Bot.

• In Camel: Pneumonia, Pox, orf, nasal pot.

Signs of Rhinitis Redness and swelling of mms of the nose.Bilateral nasal discharge which usually begins watery then mucopurualnt & purulent.Swelling of the submaxillary L.N.Dysphagia.The discharge may rises up and blocks the nose leading to "snorting".When there is irritation the animal rubs its nose against any hard objects. There may be lacrimation and bleeding

Complications

Chronic rhinitis may extend to other parts as nasal sinus giving rise to sinusitis.

Enlargement of submaxilary L.N.

Conjunctivitis specially in sheep.

Extension of the inflammation to the lung

Treatment of Rhinitis.• According to the cause.• Removal of discharge & irrigation of the

nasal cavity by N. saline.• Nasal antiseptic & decongestant.• Br. S. Antibiotic when necessary.• Anti-inflammatory and anti-histaminic.• For estrus ovis
