Abstract
This study was 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
were inspected at post-mortem in both areas (136 camels in Tamboul and
70 camels in Nyala abattoir). The survey 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 were 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 were 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) were
found to be associated with other pathological lesions. Nevertheless, the
adjacent hydatid cyst sections showed pueumonia changes viz; emphysema,
oedema, atelectasis, alveolar congestion, peribronchial lymphoid
tissue hyperplasia and interstitial pneumonia.
pneumonic causes were . detected as 32% of the total
condemnations and the microorganisms involved were, 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%.
Experimental infections in rats with different representative
isolates were conducted using intraperitoneal, intramuscular and
subcutaneous routes. The numbers of organisms inoculated per one ml
range from 1.1×109 CFU ml to 8.8×107 for Gram positive organisms and
from 1.6×107 CFU/ml to 4.8×108 CFU/ml for Gram negative
organisms.The inoculated isolates did not produce deaths in rats up to 15-
17 days post inoculation. However, post-mortem findings in some rats
inoculated intraperitoneally showed congestion of lungs, heart, liver,
liver fatty change, hydropic degeneration of kidneys and visceral
congestion.
The histopathology of pneumonic bacterial sections showed
purulent bronchopneumonia, abscessation, haemorrhages, fibrinous
pneumonia, granulomatous and interstitial pneumonias.
The sections from pneumonic lungs that did not reveal bacterial
growth, showed interstitial pneumonia, bronchopneumonia, congestion,
oedema, atelectasis and emphysema.
The mediastinal lymph nodes sections stained with H&E showed
various degrees of lymphadenitis. The other mediastinal lymph node
sections which stained with Zeihl Neelson stain revealed acid fast
tubercle bacilli in one section.
