“…Among these diseases inflammatory and noninflammatory conditions affect the respiratory system. The respiratory tract system is a major organ that plays a crucial role in respiration called the ventilation system which is a limited gas exchanged via the respiratory construction and outside atmosphere (Yousif et al 2019). The lung, the main organ of the respiratory system, is susceptible to many infectious and non-infectious agents causing different pathological conditions in farm animals (Alam et al 2001;.…”

Diseases of the respiratory system are common in all species of domestic animals, and there are many different factors acting together to cause the appearance of the disease which results in economical loss. This study was aimed to describe the prevalence of bacterial agents, isolation, identification, and molecular diagnosis in Duhok Province This study was conducted on 4061 slaughtered animals which were divided into sheep (3667) and ( 394) goats at Duhok abattoir, from September 2020 to September 2021. Two hundred fifty-three affected lungs were collected from slaughters of sheep and goats. Different media and biochemical tests were used for the isolation and identification of different types of bacterial species from affected lung samples. The results of bacterial isolation detected seven different species of gram-positive and negative bacteria. The result found that highest percentage rate was recorded with Staphylococcus aureus while lowest rate was with Pseudomonous spp they were identified by colony morphology and the traditional biochemical examination. In conclusion, the current study found that there were different species of bacteria that causes pneumonia in small ruminant at the Duhok abattoir.

Background Lung is susceptible and vulnerable to many infectious and non-infectious agents. From this, a large number of specific and nonspecific diseases conditions can be diagnosed. A cross-sectional study design was conducted from December 2022 to May 2023 on major pulmonary lesion of sheep and goat slaughtered at Dessie municipal abattoir with the objective of characterizing the pulmonary pathological lesions, and isolating and identifying potential aerobic bacteria and parasite from pneumonic lung. Materials and Methods A total of 420 (302 sheep and 118 goats) were examined for gross lung lesions and histopathological investigation using standard techniques. Additionally, detailed pathological investigation was conducted on purposively selected lung lesions. Besides, pneumonic lesions were subjected to routine bacteriological and parasitological analysis. Results The overall abattoir prevalence of pulmonary abnormalities in sheep and goat was 81.2% (341/420). The common gross lesions encountered were Pneumonia (55.5%), emphysema (7.1%), atelectasis (3.3%), Hydatid cyst (4.3%), congestion (2.4%), haemorrhage (3.1%), Anthracosis (0.9%), adhesion (0.7%), and Bronchoectasis (0.7%) respectively. Pneumonia, hydatidosis, and pulmonary emphysema were significantly associated (p < 0.05) with animal age groups. Pneumonia was the most common disorder, accounting for 233 (55.5%). Dictyocaulus filaria (47.7%), Mullerius capillaries (23.2%) and Protostrongylus rufescens (17.16%) were isolated lung worm parasites; whereas E. coli (20.6%), Klebsiella Pneumoniae (12.7%), Mannheimia haemolytica (10.8%), Streptococcus species (4.9%), Staphylococcus aurous (7.8%) and Pasteurella multocida (2.9%), Pseudomonas (6.9%), Proteus (1.9%) and Cornybacterium (1%) were the isolated bacteria. Moreover, 18 (4.3%) Hydatid cysts were identified by cyst viability test. The pulmonary disorder of sheep and goats in the study are relatively high prevalent and posing great health and economic impacts. Conclusion Pulmonary infection with different agents is very common in the study areas. Feasible and affordable control measures and using latest diagnostic techniques like molecular detections of bacteria, viruses, and fungi, is necessary.

The present study aimed to identify the topography, morphology, histochemistry and histology of lung structures, bronchial divisions and trachea in adult local Squirrel (Sciurus anomalus) as a species inhabited in Iraqi environments. This work was conducted on thirty local Squirrel of both sexes (15) males and (15) females were divided into three equal groups, first for http://wsx5customurl.comanatomical perceptions, second to resin cast technique and the third for histological study. Anatomically, in both sexes, the trachea appeared as a cartilaginous structure consisting of flexible cartilaginous rings, C-like, connected by annular ligaments. It begins at the end of the cricoid cartilage from the level of the second cervical vertebra to the fourth thoracic vertebral plane; eventually, it splits into the right and left main bronchi. Count tracheal rings, the entire weight of the lung, full length, the diameter of the trachea and right and left bronchi. The trachea in females was slightly less than in males but not significantly. The bronchial tree was detected in resin cast, which was constructed of the trachea divided into left and right primary bronchi (Main bronchi), the right one was split into four secondary bronchi to enter the right lobes and two secondary bronchi to the left one. The left lung contains one lobe, whereas four lobes were observed in the right. Histologically, the wall of the trachea consists of four layers. Epithelial cells of ciliated pseudostratified columnar and goblet cells that reacted positively with PAS were covered in the mucosa. Submucosa was devoid of the tracheal glands. The Trachealis muscle is connected from the outer aspect of rings. Similarly to the trachea, the primary bronchi are structured but smaller in diameter; they break up within the lung into primary, secondary and tertiary bronchi, then it terminates in respiratory bronchioles that contain Clara cells and open at the end in the sacs of alveoli. Two types of pneumocystis were observed lining the alveoli. The current study concluded anatomically and histologically that there were no significant differences between males and females of local squirrels. The lobulation of the lung in squirrels is different from other animals. The trachea and lung histologically resembled numerous animals, however, the wall had micro morphometric changes. But, the surface lining cells of the tracheal and bronchi mucosa secrete neutral mucin, with no submucosal glands in the tracheal wall.
