Modern thought often places fruits and vegetables at odds with each other. A food can belong to one but not both. Botanically speaking, a fruit develops from the wall of a plant's ovary and encases the seeds, so back in 1893, John Nix was right: Botanists consider tomatoes a fruit, not a vegetable.
Upper Respiratory Tract Infection in Dogs. Upper respiratory tract infections in the dog are most commonly due to bacteria and viruses. Until recently most clinicians assumed that dogs with acute onset nasal discharge, conjunctivitis, sneeze and cough had âkennel coughâ caused by Bordetella bronchiseptica.
Definition and Causes. Upper respiratory tract infection (URI) is a nonspecific term used to describe acute infections involving the nose, paranasal sinuses, pharynx, larynx, trachea, and bronchi. The prototype is the illness known as the common cold, which is discussed here, in addition to pharyngitis, sinusitis, and tracheobronchitis. Influenza is a systemic illness that involves the upper respiratory tract and should be differentiated from other URIs.
