- canine viral r. — see kennel cough.
- dust r. — steers in a feedlot fed on a finely chopped ration develop a syndrome of cough, nasal and ocular discharge but without signs of fever or toxemia.
- feline viral r. (FVR) — an acute upper respiratory infection of cats, caused by feline herpesvirus. Sneezing, coughing, ocular and nasal discharges, and often chemosis, keratitis and corneal ulceration are the main signs. Occasionally there is fatal pneumonia or generalized infection in young kittens. Most cats recovered from infection become lifelong carriers of the virus, with shedding precipitated by stress. See also feline viral respiratory disease complex.
- infectious bovine r. — see infectious bovine rhinotracheitis.
