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.
Viral illnesses are the most common cause of upper respiratory symptoms. Symptoms of a viral illness often appear over several hours without prior illness. Common viral illnesses include colds and the flu (influenza). Bacterial respiratory tract infections are less common than viral infections.acterial infections may develop after a viral illness such as a cold or the flu. Bacterial infections may affect the upper or lower respiratory system, and symptoms tend to localize to one area.
