  1. Respiratory System diseases Rhinitis (runny nose) Dr. Mohamed Ghanem www.drghanem.co.nr

  2. Rhinitis (runny nose) • Rhinitis is the term applied to an infection or inflammation of the nose characterized clinically by sneezing and nasal discharge . If the sinuses are also involved, it is called sinusitis

  3. Etiology • Bacteria such as • Staphylococcus and • Streptococcus • viruses such as • parainfluenza, adenovirus, • canine distemper and • herpes

  4. Clinical Signs • excessive nasal discharge, occasionally becoming a thick yellow or greenish-colored mucous. • The dog may sneeze frequently, trying to clear the nasal passages of mucous. • In advanced cases, the mucous may become bloody. • The dog's sense of smell is usually impaired, which may affect its appetite

  5. Dried nasal discharge - rhinitis

  6. Diagnosis • Case History • Clinical Signs

  7. Treatment • 1- Hygienic treatment • Complete rest • Isolation from other pets to minimize the spread • 2- Medicated • Antibiotic based on culture and sensitivity • amoxcillin • Keflex • Antihistamininc such as avil • Vaporizer to facilitate breathing

  8. Diseases of Respiratory System Pneumonia

  9. Definition: Inflammation of the lung tissue that usually preceded by bronchitis (bronchopneumonia) It is characterized clinically by fever, coughing and Dyspnea

  10. Etiology I- Predisposing factors Environmental exposure to dusts, smoke and II- secondary to heart diseases (Heart Failure) III- Aspiration Pneumonia Secondary to megaesophagus

  11. IV- Infectious causes • Fungal Pneumonia • Coccidioidomycosis immitis, • Cryptococcus neoformans • Viral Pneumonia • caninedistemper virus infectionor • a complicated feline upper respiratory infection • Parasitic Pneumonia • lungworms (paragonimus spp. Aelurostrongylus) • from the migration of other worms through the lung (Toxocara) • Bacterial Pneumonia • secondary to severekennel coughparticularly in young puppies V- Allergic Pneumonia: extrinsic allergic alveolitis

  12. Clinical signs • Rapid breathing (tachypnea) • Respiratory distress (Dyspnea) • Productive cough (Coughing is frequent, painful and, in the final stages, they can be produced by such severe paroxysms that the animal becomes exhausted rapidly) • Fever (40 -41 C) and Depression • Mucopurulent nasal discharge • Anorexia • Listlessness (laziness) • weight loss, activity or exercise intolerance • The tongue, gums, and lips may appear bluish (cyanosis) • Lung sounds are often abnormal with a “crackle” upon auscultation when the dog takes a deep breath

  13. Diagnosis • Case History • Clinical signs • Lab Exam • Complete blood count (CBC) • Airway cytology • Culture (tracheal wash cytology and culture and sensitivity) • Chest X-rays • Bronchoscopy

  14. Treatment I- Hygienic Treatment • Plenty of fluids and warmth • Rest II- Medicated Treatment • Antibiotics for at least three weeks or longer • Humidified oxygen for animals that have trouble breathing • Airway humidification to assist in expectoration of secretions • Percussion of the thorax (coupage) to help loosen and remove secretions • Expectorants • Bronchodilator therapy • Cough suppressants
