| dc.description.abstract | A cross-sectional study was conducted from November 2016 to May 2017 on reproductive organs of cows and dromedary camels slaughtered at Akaki slaughter house, Addis Ababa and Adama municipal abattoirs to compare lesions and bacteria isolates. A total 280 reproductive organs (140 form cows and 140 from camels) were grossly inspected. Grossly visible lesions were documented and tissue samples with lesion were collected for histopathological lesion characterizations and bacteriological isolations. Various pathological lesion with different degrees of severity were observed in 36.4% (n=51) and 34.2 % (n=48) of cows and dromedary camels, respectively. Age, species and body conditions of animals were not statistically associated with most of the disorders (P>0.05). Comparatively, in cow the most frequently observed lesions were that of ovaries 16.4% while in camels it was that of uterus 21.4%. Grossly, endometritis were characterized by congestion in acute cases and congestions and thickening in chronic cases. Microscopically, endometrial glands degenerations, sloughing of epithelium, periglandular cuffing and infiltrations of inflammatory cell were some of characteristics change observed in endometritis. Grossly, the follicular cyst were large, some of them occupied the entire ovary and very thin walled. Microscopically, the follicular cysts were characterized by extremely thin granulosa layers. Most of endometritic tissues cultured for bacterial isolations were positive for either single and/or mixed bacterial infection. Staphylococcus species 28.5%, Streptococci species 19.6%, Coynebacterium species 8.9%, Escherichia coli 26.7%, Salmonella species 10.7% and Klebsiella species 5.35% were isolated from cows uteri, while in the dromedary camels, Escherichia coli 35.5%, Staphylococcus species 26.6%, Streptococcus species 13.3%, Pseudomonas species 6.6 %, Proteus species 4.4%, Salmonella species 8.8% and Klebsiella species 4.4% were isolated. It could be concluded that reproductive organ lesion were important problem in both species of animals and these disorders might be causes of infertility and appearance of these females in abattoir. The role of each identified lesion on infertility needs further investigations. | en_US |
