Feline infectious upper respiratory disease

INFECTIOUS upper respiratory disease in cats remains a common problem, despite widespread use of vaccination against the feline respiratory viruses over the past 20 years. This is partly due to the fact that, while vaccination reduces the severity of disease, it will not protect against viral infection, and does not eliminate or prevent the development of carrier states. The involvement of other pathogens, such as [i]Bordetella bronchiseptica[/i] and [i]Chiamydia psittaci[/i], in the syndrome may also be significant.
