“…CPR is associated with Salmonella enterica subsp. Diarizonae , and the main lesion may look like a tumour, but lesions are mostly located in ventral turbinates and almost never in ethmoidal ones as in the case of ENA [ 76 ].…”

We review three neoplastic wasting diseases affecting sheep generally recorded under common production cycles and with epidemiological and economic relevance in sheep-rearing countries: small intestinal adenocarcinoma (SIA), ovine pulmonary adenocarcinoma (OPA) and enzootic nasal adenocarcinoma (ENA). SIA is prevalent in Australia and New Zealand but present elsewhere in the world. This neoplasia is a tubular or signet-ring adenocarcinoma mainly located in the middle or distal term of the small intestine. Predisposing factors and aetiology are not known, but genetic factors or environmental carcinogens may be involved. OPA is a contagious lung cancer caused by jaagsiekte sheep retrovirus (JSRV) and has been reported in most sheep-rearing countries, resulting in significant economic losses. The disease is clinically characterized by a chronic respiratory process as a consequence of the development of lung adenocarcinoma. Diagnosis is based on the detection of JSRV in the tumour lesion by immunohistochemistry and PCR. In vivo diagnosis may be difficult, mainly in preclinical cases. ENA is a neoplasia of glands of the nasal mucosa and is associated with enzootic nasal tumour virus 1 (ENTV-1), which is similar to JSRV. ENA enzootically occurs in many countries of the world with the exception of Australia and New Zealand. The pathology associated with this neoplasia corresponds with a space occupying lesion histologically characterized as a low-grade adenocarcinoma. The combination of PCR and immunohistochemistry for diagnosis is advised.

“…Pathological findings show a swollen ventral turbinates with a roughened surface. The section of the turbinate shows a proliferative tissue that is usually composed of multiple small white or yellow polypoid structures covered by mucus, although only a thickening of the mucosa can be observed (Lacasta et al, 2012;Rubira et al, 2018).…”

Diagnostic imaging techniques are very useful non-invasive methods to obtain medical images for the diagnosis of respiratory diseases in sheep. The use of ultrasound and thermographic cameras must be enhanced at farm level with the objective of assisting in the diagnosis of major respiratory diseases present in sheep farms. X-ray and, particularly, computed tomography are very interesting tools to facilitate the understanding of the main pathological processes in sheep, especially at the respiratory level. This article shows more than 40 images of thermograms, X-ray, ultrasonography and computed tomography of the most significant respiratory diseases in sheep.

“…CPR is becoming a more commonly diagnosed disease not only in Spain but also in other countries in Europe and America 3–6. To date, in all the descriptions made of this disease, the ventral turbinate was always affected unilaterally or bilaterally, and only minor changes were observed in the dorsal turbinate or ethmoidal area 2 3 5. In the case reported here, a detailed description is made of the condition of the dorsal and partially ethmoidal turbinate, showing how this bacterium can deepen the respiratory tract, affecting more seriously internal structures.…”

“…When this bacterium becomes intracellular, it produces an intense inflammatory reaction, giving rise to the typical clinical signs of the disease. In these cases, it has been noted that the bacteria cause intense inflammation of the ventral nasal turbinate with proliferation of polypoid tissue inside, in a chronic and progressive way 2. This fatal prognosis disease causes loss of weight, no fever, snoring, seromucous nasal secretion and nasal deformation.…”

Chronic proliferative rhinitis (CPR) is a fatal prognosis upper respiratory tract disease that affects sheep and is associated with Salmonella enterica subspecies diarizonae serotype 61:k:1, 5, (7). It may be unilateral or bilateral, and although minor changes have been seen in dorsal turbinate, the ventral turbinate is always affected, which makes it possible to observe the proliferative tissue emerging from the nares.The following publication describes the case of an ewe severely affected by a bilateral inflammatory process of the upper respiratory tract. S enterica subspecies diarizonae was isolated from nasal swabs; however, the hottest area observed by a thermal imaging camera was not the ventral area, as usually seen in this process, but the middle area, where the dorsal turbinate is located. In addition, no proliferative tissue was seen through the nostril. At postmortem examination, it was confirmed that CPR seriously affected, for the first time, the dorsal turbinate and ethmoidal areas. Thermographic cameras are useful tools for the diagnosis of upper respiratory tract diseases in sheep.
