LacastaAbstractChronic proliferative rhinitis (CPR) is a slow and progressive upper respiratory tract disease of sheep with a poor prognosis for affected animals. It causes a proliferative inflammation of the ventral nasal turbinates with uni or bilateral affection that may totally obstruct the nasal cavity. Salmonella enterica subspecies diarizonae serovar 61:k:1,5,(7) has been associated with the disease. This microorganism, host-adapted of tonsils and nasal cavity of sheep, has been isolated in pure culture from the nasal cavity in all reported cases of CPR. However, its etiopathogenesis, mechanism of transmission and its involvement with the disease are still unknown. The present article focuses on describing the current knowledge about this disease gathering the published information and offering some new data on the latest research carried out on chronic proliferative rhinitis in sheep.
