Camels are the most efficient domesticated animals in arid and semiarid areas of the world. In Ethiopia, they are the main livestock kept to sustain the livelihoods of pastoralists, as camels are used for milk and meat production and also for transportation. However, she-camel reproductive diseases are one of the major constraints for camel-producing communities. A cross-sectional study was conducted from November 2018 to December 2019 to identify and characterize pathological lesions and isolate possible bacteria associated with reproductive diseases and disorders in she-camels slaughtered at Dire Dawa and Babille municipal abattoirs. A total of 155 study animals were examined by recruiting all she-camels slaughtered during every abattoir visit. Overall, 562 reproductive organs, the ovaries, oviducts, uterus, and cervix, were examined through observation, palpation, and incision, and the animal- and organ-level pathological lesion prevalence were found to be 29% and 64.6%, respectively. Degenerative changes, inflammatory lesions (endometritis and salpingitis), growth disturbances (e.g., ovarian hypoplasia), and noninflammatory lesions (e.g., noninflammatory edema) were the identified pathological lesions. Occurrences of pathological changes among reproductive organs had differences where significantly the highest proportion ( = 0.00) was observed in the uteri. Of the 119 microbiological samples processed, 77.3% were positive for single or mixed bacterial genera, from which 7 different bacterial isolates and 14 other unidentified Gram-negative bacteria were detected. , a, and spp. were the most frequently isolated organisms with 28.2%, 26.9%, and 12.8% frequencies, respectively. The result of the questionnaire survey showed 74% of the respondents had culled the she-camel at productive age because of poor reproductive performance associated with refused mating, abortion, and repeat breeding (poor conception). On the other hand, a majority of camel herders had poor to no information and access to modern veterinary services; nevertheless, they had good indigenous knowledge on how to manage reproductive abnormalities. Considering the importance of camels in our study area, further research on camel reproductive diseases and abnormalities with wider sample and epidemiology need to be conducted using molecular and hormonal assay techniques.
骆驼是世界干旱和半干旱地区最高效的家畜。在埃塞俄比亚,骆驼是维持牧民生计的主要牲畜,因为骆驼可用于产奶、产肉以及运输。然而,母骆驼的生殖疾病是骆驼养殖社区面临的主要制约因素之一。2018年11月至2019年12月开展了一项横断面研究,以识别和描述病理损伤特征,并分离与在德雷达瓦和巴比勒市屠宰场宰杀的母骆驼生殖疾病和紊乱相关的可能细菌。通过招募每次屠宰场参观期间宰杀的所有母骆驼,共检查了155只研究动物。总体而言,通过观察、触诊和切开检查了562个生殖器官,即卵巢、输卵管、子宫和子宫颈,发现动物和器官层面的病理损伤患病率分别为29%和64.6%。已识别的病理损伤包括退行性变化、炎症性损伤(子宫内膜炎和输卵管炎)、生长障碍(如卵巢发育不全)和非炎症性损伤(如非炎症性水肿)。生殖器官中病理变化的发生率存在差异,其中子宫中观察到的比例最高(=0.00)。在处理的119份微生物样本中,77.3%的样本对单一或混合细菌属呈阳性,从中检测到7种不同的细菌分离株和14种其他未鉴定的革兰氏阴性菌。 、 、 分别是最常分离出的微生物,频率分别为28.2%、26.9%和12.8%。问卷调查结果显示,74%的受访者因与拒绝交配、流产和反复配种(受孕困难)相关的繁殖性能不佳而在母骆驼育龄期将其淘汰。另一方面,大多数骆驼牧民对现代兽医服务了解甚少或无法获得相关服务;尽管如此,他们在如何管理生殖异常方面拥有丰富的本土知识。考虑到骆驼在我们研究区域的重要性,需要使用分子和激素检测技术,对骆驼生殖疾病和异常进行更广泛样本和流行病学的进一步研究。
