Variabilities of hydatidosis in domestic animals slaughtered at Cairo and Giza abattoirs, Egypt

Abstract

Aim: 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. Materials and Methods: 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. Results: 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. Conclusion: 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.

Epidemiological, Morphometric, and Molecular Investigation of Cystic Echinococcosis in Camel and Cattle From Upper Egypt: Current Status and Zoonotic Implications

“…Furthermore, the present data illustrate the occurrence of hydatid cysts in aged cattle at a rate of 2.6% (5 infected out of 175 examined animals), while no infection was detected among young cattle (<5 years of age) ( N = 400). The present findings agree with several previous studies performed either at the national (Egypt) or international level ( 70 , 78 , 79 ). This observation could be attributed to the fact that older animals are exposed to infection more than young ones and aged animals get slaughtered more than young ages, since their production (calves/milk) and working capacity decrease ( 80 ).…”

“…In accordance with the studied potential variable factors, the statistical analysis revealed that the number and type of cysts, organ involved, and fertility and viability of hydatid cysts were not significantly associated with the occurrence of the of CE in camels or cattle. The present study also showed that CE were only detected in the lungs of camels, while cysts occurred mainly in the lungs of cattle and only one cyst was reported in the liver of cattle, which is consistent with several previous reports, mainly from Egypt ( 69 , 70 , 72 ). However, some previous reports revealed that the parasite exhibited single-organ involvement, although the involvement of two organs has also been recorded, which is apparently associated with the specific geographic regions and strain of the parasite ( 25 , 76 , 77 ).…”

“…The present rates of CE are lower than those of a previous study performed in cattle from Egypt, which reported an occurrence rate of 3.3% ( 69 ). Another study performed in Cairo reported that 18.4% of the examined cattle were infected by CE ( 70 ). In contrast, the occurrence rate obtained in the present study was higher than those reported in cattle slaughtered in abattoirs in Assiut, Mansoura, and other provinces of Upper Egypt, where hydatid cysts were noted in 0.4, 0.068, and 0.004% of the examined animals, respectively ( 25 , 71 , 72 ).…”

“…Furthermore, the present study showed that female cattle were infected exclusively, at rate of 2.6% (5 infected out of 175 examined animals), while no infection was detected in the examined male cattle. This observation may be explained by the fact that female animals are not slaughtered at younger ages, as the owners mostly keep them for breeding, obtaining calves and for milk production; in contrast, male cattle are slaughtered at younger ages ( 70 , 82 , 83 ). The management practices might also contribute to this difference since males move far away for grazing; meanwhile females are usually kept homesteads, making females are more exposed to infection than males ( 84 ).…”

The Prevalence of Hydatidosis in Ruminants of Different Iraqi Regions

“…In Al Muthanna province, the results revealed that buffalo hydatidosis recorded the highest incidence percentage (5.5%) followed by Camel (3.7%), this findings be in accordance with Abo-Aziza et al, (2019) who found that slaughtered buffalo and camel at Cairo and Giza abattoirs were highly infected with hydatidosis.…”
