Diseases of the Respiratory System

Chapter 69 Diseases of the Respiratory System


Respiratory diseases can have a significant impact on a flock or herd through lower milk production, slower growth, and the economics involved with treating the diseases. Respiratory disease may not be noticed by many owners until it has progressed to a fairly serious condition, because many owners do not examine their individual animals on a daily basis.



OESTRUS OVIS INFESTATION


Oestrus ovis infestation is a condition caused by a fly that deposits larvae around a sheep’s or goat’s nostrils. The larvae then migrate into the nasal cavity and sinuses; then they fall out and pupate on the ground.




CLINICAL SIGNS



• Secondary bacterial infections

• Sinusitis

• Shaking of the head

• Rubbing of the nose

• Nasal discharge


DIAGNOSIS



• Endoscopy, visualizing the larvae


TREATMENT



• Ivermectin will kill the fly larvae


SINUSITIS


Sinusitis is a rare condition in sheep and goats, usually secondary to some other condition. Frontal sinus infections are usually found in animals that have a history of recent dehorning, whereas tooth problems are the most common cause of maxillary sinus infections.




CLINICAL SIGNS



• Discharge

• Facial asymmetry

• Foul odor

• Occasional signs of systemic disease


DIAGNOSIS



• Clinical signs


TREATMENT



• Lavage of the affected sinus

• Systemic antibiotics if needed


INFORMATION FOR CLIENTS



• Keeping the head bandaged after dehorning may prevent sinusitis from occurring.


PASTEURELLOSIS


Pasteurella haemolytica is one of the most important bacterial diseases of sheep and goats. This bacterium can cause severe, life-threatening pneumonia. The bacterium is a normal inhabitant of the upper respiratory tract, but during times of stress and when the animal is immunocompromised, it can cause deleterious effects.




CLINICAL SIGNS



• Nasal discharge
