Clinical Signs and Diagnosis
The bacteria invade the lacrimal glands of the eye, causing keratitis, uveitis and ulceration. Cattle show signs of pain, increased lacrimation, excessive blinking and conjunctivitis.
More severe cases may show systemic signs such as inappetance and weight loss. Chronic untreated cases can become blind.
Diagnosis is usually based on the clinical signs, but the bacteria can be cultured from lacrimal swabs, or visualised on smears of lacrimal secretions.

“The signs look better. The Father of Waters again goes unvexed to the sea. Thanks to the great North-West for it. Nor yet wholly to them.... The job was a great national one.”
