Upper respiratory tract disorders RHINITIS, 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.
