The effect of some variables on hydatidosis in animals slaughtered at Cairo and Giza abattoirs was investigated and the influence on serum biochemical parameters, antioxidant enzymes, and histopathological lesions caused by these parasites as a consequence was estimated.
The effect of some variables on hydatidosis in 397 sheep, 401 cattle, 435 buffaloes, and 341 camels slaughtered at Cairo and Giza abattoirs was investigated, and the influence on serum biochemical parameters, antioxidant activity and histopathological lesions caused by these parasites as a consequence was estimated.
The results revealed that 39 sheep (9.8%), 74 cattle (18.4%), 95 buffaloes (21.8%), and 79 camels (23.25%) were infected. Concerning age variations, 165 young and 232 adult sheep, 215 young and 186 adult cattle, 194 young and 241 adult buffaloes, and 112 young and 229 adult camels were examined. The prevalence of hydatidosis was higher in adult sheep, cattle, and camel; 32 (13.8%), 49 (26.3%), and 56 (24.5%) than the younger ones 7 (4.2%), 25 (11.6%), and 23 (20.5%), respectively. Two hundred and eighty-eight sheep, 171 cattle were examined during winter. However, 109 sheep, 230 cattle were examined during summer. Hydatidosis infection in sheep and cattle was higher in winter 26 (9.01%) and 47 (27.5%) than in summer 13 (11.9%) and 27 (11.7%), respectively. Out of 133 sheep and 128 camels slaughtered in El-Basatin abattoirs, 36 (15.3) and 38 (29.7%) showed higher prevalence than that from El-Warak and El-Moneib abattoirs. Comparing with the non-infected groups, alkaline phosphatase activity decreased in hydatid-infected animals, while cholesterol and liver enzymes activities increased. Total lipid and triglyceride levels decreased in infected camels. Glutathione peroxidase, superoxide dismutase, and catalase decreased in hydatid-infected animals.
The disturbance in the biochemical parameters, liver enzymes, and the antioxidant activities was consistent with the pathological findings that indicated the risk of hydatidosis infection. Finally, this study clarified the variabilities of hydatidosis in Cairo and Giza abattoirs as a starting point for future studies in different regions in Egypt.
研究开罗和吉萨屠宰场中一些变量对动物包虫病的影响，并评估这些寄生虫对血清生化参数、抗氧化酶以及由此导致的组织病理学损伤的影响。
研究开罗和吉萨屠宰场宰杀的397只绵羊、401头牛、435头水牛和341峰骆驼中一些变量对包虫病的影响，并评估这些寄生虫对血清生化参数、抗氧化活性以及由此导致的组织病理学损伤的影响。
结果显示，39只绵羊（9.8%）、74头牛（18.4%）、95头水牛（21.8%）和79峰骆驼（23.25%）受到感染。关于年龄差异，检查了165只幼年绵羊和232只成年绵羊、215头幼年牛和186头成年牛、194头幼年水牛和241头成年水牛、112峰幼年骆驼和229峰成年骆驼。成年绵羊、牛和骆驼的包虫病患病率高于幼年动物，分别为32只（13.8%）、49头（26.3%）和56峰（24.5%），而幼年动物分别为7只（4.2%）、25头（11.6%）和23峰（20.5%）。冬季检查了288只绵羊和171头牛，夏季检查了109只绵羊和230头牛。绵羊和牛的包虫病感染率冬季（分别为26只（9.01%）和47头（27.5%））高于夏季（分别为13只（11.9%）和27头（11.7%））。在巴萨廷屠宰场宰杀的133只绵羊和128峰骆驼中，36只（15.3%）和38峰（29.7%）的患病率高于瓦拉克和莫奈卜屠宰场。与未感染组相比，包虫感染动物的碱性磷酸酶活性降低，而胆固醇和肝酶活性升高。感染骆驼的总脂质和甘油三酯水平降低。包虫感染动物的谷胱甘肽过氧化物酶、超氧化物歧化酶和过氧化氢酶降低。
生化参数、肝酶和抗氧化活性的紊乱与表明包虫病感染风险的病理结果一致。最后，本研究阐明了开罗和吉萨屠宰场包虫病的变异性，作为埃及不同地区未来研究的起点。
