Bacteriological and pathological studies on condemned lungs of one humped camels (cameleus dromedarius)‎ slaughtered in Tamboul and Nyala abattoirs, Sudan

الملخص EN

This study has been carried out in Central region of the Sudan (Tamboul abattoir) and Western region (Nyala abattoir) to investigate the condemnation causes of camel’s lung.

Two hundreds and six camel lungs are inspected at post-mortem in both areas (136camels in Tamboul and 70camels in Nyala abattoir).

The survey has revealed different causes of camel’s lung condemnation with slight variations between the two areas of survey.

The main causes of lung condemnation in Tamboul are found to be parasitic (Hydatidosis) 40.4%, pneumonia 19.1%, caseated nodules 8.8%, emphysema 6.6%, necrosis 5.9%, fibrosis 4.4%, abscess 2.9%, aspirated blood 2.2% and adhesions 1.5%.

In Nyala the causes of condemnation are found to be, Hydatidosis 61.4%, pneumonia 31.4%, fibrosis 12.9%, abscess 8.5%, caseated nodules 5.7%, fibrosis 12.9% and emphysema 2.9%.

Grossly 35.7% of the total hydatidosis infection (98 lungs) is found to be associated with other pathological lesions.

Pneumonic causes are.

detected as 32% of the total condemnations and the microorganisms involved are, Staphylococcus spp.

27.9%, Corynebacterium spp.

13.9%, Streptococcus spp.

13.9%, Bacillus spp.

12.8%, Pneumococcus spp.

11.8%, Enterobacteria spp.

9.6%, Micrococcus spp.

6.4%, Haemophilus spp.

2.1%, Actinomyces spp.

1.07%, Pasteurella spp.

1.07% and Pseudomonas spp.

1.07%.

The histopathology of pneumonic bacterial sections showed purulent bronchopneumonia, abscessation, haemorrhages, fibrinous pneumonia, granulomatous and interstitial pneumonias.

The mediastinal lymph node sections which stained with Ziehl Neelson stain revealed acid fast tubercle bacilli in one section.
