Infectious sinusitis—also known as swelled head, turkey roup and nasal catarrh —is a disease which is responsible for the deaths of many turkeys every year. Even where birds recover from the disease, they are liable to be stunted and unthrifty and it is generally agreed that sinusitis ranks second only to blackhead as a source of mortality and financial loss.
