“…Ovine pulmonary adenomatosis was found in 6.81% of pneumonic sheep lungs. Such a result was higher than those reported in previous studies (Mishra et al 2018;Singh et al 2018;Mekibib et al 2019;Hashemnia et al 2019).…”

Bovine parainfluenza 3 virus is a common virus that causes respiratory tract infection in cattle, sheep, and goats worldwide. The objective of this study is to identify macroscopic and histopathological lung lesions in slaughtered sheep during the period from December 2018 to December 2019 and to determine the presence of Bovine parainfluenza 3 virus (BPI3V) in frozen sheep pneumonic lung using a direct immunofluorescence antibody technique (DFAT). The overall prevalence of lung affection was 11% (1440/13084). The gross lesions were acute bronchopneumonia (58.12%), interstitial pneumonia (07.15%), fibrinous bronchopneumonia (10.70%), suppurative bronchopneumonia (03.47%), verminous pneumonia (13.75%), and ovine pulmonary adenomatosis (06.81%). There was a significant difference in the rate of pulmonary lesions according to the seasons of the study. The lesions were more frequently observed in autumn and winter with a rate of 34.17% and 28.05%, respectively. The DFAT was carried out only on 107 pneumonic samples with interstitial pneumonia, fibrinous bronchopneumonia, and acute bronchopneumonia. The BPI3V antigens were detected in 12 samples (11.21%). This is the first study that revealed the presence of the BPI3V in pneumonic sheep lungs in Batna region using the direct immunofluorescence antibody technique. The latter may be used for definite diagnosis when histopathological modifications in pneumonic sheep caused by this virus are difficult to distinguish from those caused by other respiratory viruses.

“…Our results showed that 1.35% of sheep and goats are affected after gross examination of lung samples, while around 45.45% of samples were improved via histopathological investigation. This data in disagreement with some authors [9,12] and this is variation could belong to group or herds of animals, housing, breed, sex, age, management conditions, source of material, location, nature of dissemination, season, and research time, environment and cultural breeding of animals [13,14], However, to obtain quite information about the prevalence of OPA of the world is difficult because OPA is not appropriate disease and therefore very few countries collected data around the diagnosis of a number of cases of disease also Singh et al [15] recorded that the most of sheep affected with disease is in belong to housing system mainly during the cold weather, may have a substantial impact on the prevalence of OPA and the time during when animals are maintained closely [16]. Macroscopically our study showed that the lesions of OPA are varied from structure which is either classical or typical form and growth of tumor cells appears as multifocal nodules or complete consolidation of the entire lungs tissues and in the color which was varied from white to grayish in color [6,7,17] as well as the study showed excessive amounts of fluids in the trachea and lungs of affected samples which was an outstanding finding to distinguish the OPA from others disease of respiratory system and these findings have been investigated in other researches as important point for diagnosis of OPA, these researches are in agreement that the characteristic clinical diagnostic finding of OPA is accumulation of amount fluid in lungs and these fluids is pass through out of nostrils of affected sheep and goats when the animal lowering its head to down [18].…”

T HE current study aimed to investigate the prevalence and pathological observation of ovine pulmonary adenocarcinoma (OPA) in sheep and goats at Duhok abattoir of Iraq. A total of 4061 lung samples from small ruminants (3667 sheep and 394 goats) were selected randomly from slaughtered sheep and goats. All samples were examined macroscopically is involving color, consistency, texture, adhesion, pattern, the number of the lesion, distribution, the nature of exudates and lobe of the lung are involved. Histopathological examinations were performed from 55 affected lungs The results showed that the prevalence of disease in the Duhok abattoir was 1.35% based on macroscopical features while results found 45.45% percentages of affected lung with OPA according to histopathological features, the gross lesions of OPA in sheep and goatsfound that the upper respiratory part was filled with excessive frothy material fluid and the lungs were heavy, enlargement, and edematous appearance. While the important histopathological observations of the affected parts was varied from small discrete nodules that appears white in color and are involves both lungs, measuring around 0.5-2 cm of the diaphragmatic and other lobes were recorded, and classified as classical and atypical form. Histologically results showed the presence of multiple proliferations foci of neoplastic cells in the epithelial cell of alveoli and bronchi, these proliferations appear either papillary or as the impression of solid growths appearance or acinar shape. Inconclusion our study gives important data about the prevalence and pathological changes of OPA in sheep and goats at the Duhok abattoir of Iraq.

“…Furthermore, degeneration and necrosis of the epithelial cells lining the alveoli and the cartilage was observed in 6% and this might be due to the ischemia which occurs due to vascular damage (33). The necrotic area often surrounded by edge of elongated spindle cell known as (swirling macrophages or oat cell) (34)(35)(36), and the formation of oat cell in bronchopneumonia has been contributed to the release of toxin from Gram negative bacterial infection which demonstrated in most cases of fibrins bronchopneumonia (37,38). In addition to these finding there was also deposition of calcium salt due to low pH that resulted from chronic infection and parasitic disease (11,39), hemosiderin pigment, represented by the presence of copper-colored granules inside the tissue due to present of hemorrhage inside lung tissue (35,39).…”

Respiratory system disease is common in sheep, which is frequently difficult to detectable in live animals until it becomes serious and complicated. This study was aimed to describe sheep lung lesions in Mosul city, which roam in dump zones and have been slaughtered at butchers' shops, fifty male and female sheep 1-5 years were used at the current work from March to December 2021; affected Samples were collected and prepared for standard histopathological analysis. The special stain was also used for carbohydrates demonstrated inside and around lung lesions. The results of the current study showed the presence of gross and histological finding changes, the gross lesion presented by inflammation of the upper right lope, congestion, and bleeding on all parts of the lope in addition to different sizes of the nodular lesion. In contrast, the pneumonic histological finding was 12.1%, circulatory disturbance 3.5%, parasitic infections 10.0%, disturbance of growth 7.1%, Necrotic area surround by swirling macrophage 2.0% in addition to the deposition of calcium salt and hemosiderin pigmentation. Organizing Pneumonia (OP) and Masson's bodies were one of the most detected lesions in the roaming sheep, it was scored by Masson Trichrome from mild, moderate, and severe fibrosis. All lesions were categorized according to the type of lesion, grade, and kind of it. From the current work, we demonstrated that pneumonic disorder represented a considerable and serious problem in the animal livestock industry and leads to economic loss in milk, wool, and sheep meat production. Additional studies are recommended to determine the etiological agent of sheep lung lesions whether it is a fungal, bacterial, or viral agent.
