“…In the present study, bronchopneumonia in the form of acute suppurative, acute fibrinous, and chronic bronchopneumonia accounted for the greatest proportion (56.1%) of pneumonia encountered. In agreement with the present finding, previous investigations in other countries also reported bronchopneumonia as the commonest type of pneumonia in sheep and goats [28, 29, 31, 32]. The gross and histological lesions of the different forms of bronchopneumonia were consistent with the findings of other studies [11, 33–36].…”

“…Finally the stained slides were examined systematically at 10X and 100X magnifications for the presence of characteristic and/or suggestive lesions using ordinary light microscope. The different forms of pneumonia were then classified according to the involvement of pulmonary regions and anatomical sites and nature of the inflammatory exudate and reaction present [28, 29].…”

Accurate clinical diagnosis of pneumonia, the leading cause of mortality in small ruminants, is difficult and usually requires postmortem examination of the lungs. An active abattoir survey was conducted between November 2017 and April 2018 to estimate the prevalence and characterize the gross and histopathological lesions of pneumonic lungs in 864 clinically healthy young small ruminants (490 sheep and 374 goats aged 1.5 to 3 years) raised for meat in different parts of the country and slaughtered at Elfora Bishoftu export abattoir, Ethiopia. Out of the total lungs examined grossly, pneumonic lesions were found in 158 (18.29%) lungs. On histopathological examination of the lungs with gross pneumonic lesion, however, typical pneumonic lesions were diagnosed in 148 (17.13%) lungs only. No significant (p>0.05) difference was noted in the prevalence of pneumonia between sheep (17.14%) and goats (17.11%) in histopathological examination. Based on the predominant histopathological findings, the pneumonic lesions were characterized as interstitial pneumonia (41.9%), acute suppurative bronchopneumonia (25.7%), acute fibrinous bronchopneumonia (24.3%), chronic bronchopneumonia (6.1%), aspiration pneumonia (4.7%), bronchointerstitial pneumonia (3.4%), and ovine pulmonary adenomatosis (3.4%). The study further showed the spread of ovine pulmonary adenomatosis and ovine progressive pneumonia (Maedi) from the central highlands to areas that were previously free from these diseases. Due to its better diagnostic capacity, histopathology should be employed routinely as an ancillary test in the major abattoirs and regional veterinary laboratories to generate additional epidemiological data for a better disease control and prevention measures. Further studies are also recommended to identify the etiological agents of pneumonia in sheep and goats and thereby to formulate feasible and cost-effective interventions.

“…(Figure 3B). The results of this study were consistent with those reported by (Radostits et al, 2007;Sonawne et al, 2016;Singh et al, 2017) who stated the classical presentation of the histopathological feature of the pyogranulomatous inflammation in lungs. Osman et al (2012) described similar histopathological lunglesion in a mouse model, lungs showed congestion, hemorrhage, and development of micro-abscesses, caseous necrosis and presence of tubercular like granuloma that surrounded with neutrophil and macrophage.…”

“…However, such a result was lower than the rates recorded in Iraq (Mahdi et al 2015 ) and in Ethiopia (Mekibib et al 2019 ) where fibrinous bronchopneumonia was reported in 15% and 19%, respectively. This result was close to that obtained in previous works with 11.67%, and 11.1%, respectively (Dar et al 2014 ; Singh et al 2017 ).…”

“…In the present study, acute bronchopneumonia was found in 58.18%. A much lower occurrence of this lesion was observed in previous studies (Dar et al 2014;Singh et al 2017;Mishra et al 2018;Hashemnia et al 2019;Kumar et al 2014).…”

Pathological study and detection of Bovine parainfluenza 3 virus in pneumonic sheep lungs using direct immunofluorescence antibody technique

et al. 2021

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.
