Pathology of trachea and lungs of buffaloes

Abstract

Pathological conditions of trachea and lungs of slaughtered buffaloes were investigated in the present study. A total of 80 slaughtered buffaloes were examined individually and trachea (80) and lungs (80) were collected for histopathology from the slaughterhouses of Barisal sadar, Barisal, Bangladesh, during the period from July 2006 to March 2007. Among them 9 trachea and 30 lungs were found to be apparently abnormal in naked eye. Grossly, tracheal and lungs lesions were 11.25% and 37.5% in buffaloes, respectively. The gross tracheal lesions were petechial haemorrhages on the mucosa of trachea and lungs lesions were haemorrhage and congestion in lungs (16.25%), hard nodule formation (7.5%), cyst in lungs (6.25%), emphysematous lung (5%) and thickened pleura (2.5%). In histopathology, congestion (5%) and mild tracheitis (8.75%) were recorded as tracheal lesions. Histopathological examination of lungs noticed a number of conditions or lesions such as chronic interstitial pneumonia (3.75%), edema fluid (3.75%), broncho-pneumonia (3.75%), bronchitis (2.5%), bronchiolitis (2.5%), pneumonia-congested stage (8.75%), hydatid cyst (6.25%), fibrinous pneumonia (3.75%), healed nodule (7.5%), purulent broncho-pneumonia (1.25%), fibrino-purulent pneumonia (1.25%), subacute fibrinous pneumonia (1.25%), pulmonary adenomatosis (1.25%), pleuritis (2.5%) and hemosiderosis (3.75%). For morphological descriptions, the lesions were categorized into various types; however a single section showed intermixed of various lesions.

Bacteriological and pathological investigation of goat lungs in Mymensingh and determination of antibiotic sensitivity

“…This variation might be due to some calculating factor as authors calculated out of total examined goat but this investigation was conducted within only affected lungs of goats. Histopathology of bronchopneurnomia and hemorrhagic pneumonia described in this present investigation corresponded to the lesions of other investigators (Jones et al, 1997;Alam et al, 2001;Akbor et al, 2007). Pasteurella sp.…”

Pathological Affections of Lungs in Slaughtered Cattle and Buffaloes at Chittagong Metropolitan Area, Bangladesh

“…The reason behind the higher rate of hemorrhagic lesion in buffalo is not clear at this moment and requires further investigation. The frequency of pulmonary congestion among the lung affections was 7.03% which is much less than the reports by Akbar et al (2007) that showed 16.25% of pulmonary congestions in buffalo lungs by gross examination. Pulmonary congestion occurs due to the obstruction of the pulmonary vessels and passive which is sometimes followed by pulmonary edema (Blood and Henderson, 1976).…”

“…(Cullen and Maclachlan, 2001). Akbar et al (2007) and Rahman et al (2006) showed lower frequency of pulmonary nodules.…”

“…High prevalence of hydatidosis in slaughtered carcasses was reported in Bangladesh by Kabir et al, 2010;Basak et al, 2011). Akbar et al (2007) reported 6.25% hydatid cyst from the slaughterhouses of Barisal sadar, Bangladesh. Pulmonary emphysema is often considered as the secondary lesion to traumatic pericarditis or pulmonary abscess (Blood and Henderson, 1976).…”

“…(Scott et al, 1997). The emergence of anthrax has made the society more concerned about the health issues and quality of meat animal carcass (Akbar et al, 2007). Therefore, slaughter house inspection became a very important responsibility for the local veterinary authority and municipality to determine whether or not the animal was suffering from any disease or disease condition that makes the carcass inconsumable.…”
