An Abattoir-Based Study on the Prevalence of Hydatidosis Infestation and Fertility of Hydatid Cysts in Slaughtered Herbivores (Food Animals) in Dhamar Province-Yemen.
Abstract
Cystic echinococcosis is one of the most important emerging zoonotic parasitic diseases worldwide. This\r\ndisease causes considerable economic losses and adverse public health challenges in most countries, including the\r\nMiddle East countries. This study was designed to investigate the current prevalence of hydatidosis and to determine\r\nthe fertility of hydatid cysts among some ruminants (both local and imported breeds of cattle, sheep, and goats) slaughtered\r\nin the abattoirs in Dhamar Province-Yemen. The samples were collected from the Central Corporation Slaughterhouse\r\nin Dhamar-Yemen from January 2019 to November 2020. During this period, a total of 29,071 and 5,705\r\nsamples were collected from local and imported food animals respectively. The results of analysed samples revealed\r\nthat the distribution of the hydatid cysts among the local slaughtered animals were 318 (11 .63%), 613 (5.41%), and\r\n28 (6.08%) for cattle, sheep, and goats respectively for the year of 2019 whereas in the year 2020, the results were 235\r\n(9.69%), 685 (5.74%) and 32 (6.95%) respectively. Moreover, the prevalence rates of hydatidosis among the imported\r\nanimals in the year 2019 (cattle, sheep, and goats) were 71 (4.76%), 36 (3.0%) and 39 (5.93%) while 93 (5.28%), 24\r\n(4.8%) and 34 (6.8%) were recorded in the year 2020, respectively. With respect to the fertility rates of the hydatid\r\ncysts, 1236 (55.97%) were found to be sterile, 515 (23.32%) were fertile, 323 (14.62%) were calcified, and 174 (7.88%)\r\nwere observed to have become encrusted (cheesy). Among the local breed, the fertility rate of lung hydatid cysts was\r\nhigher with 995 (45.06%), followed by the liver with 777 (35.19%), whilst in the imported breed, the fertility rates\r\nwere 152 (6.88%), and 100 (4.52%) in the lung and liver respectively. This study, observed that Echinococcus granulosus\r\nparasite was present in both large and small ruminants within the study area and was responsible for high rate of organ\r\ncondemnation. Hence, strategic endo-parasite eradication with a strong surveillance system and good management\r\npractice of animals is needed in order to limit the impact of the disease among food animals and prevent human transmission.
