Prevalence of liver fluke infections in slaughtered animals in Lorestan, Iran

Abstract

Fasciola spp. and Dicrocoelium dendriticum as liver flukes, contaminate ruminants and other mammalian extensively and cause major diseases of livestock that create considerable economic losses. This retrospective study has been done to evaluate contamination rate of slaughtered animals with fasciolosis and dicrocoeliosis at Lorestan abattoirs. In this survey, prevalence rate of fasciolosis and dicrocoeliosis in slaughtered animals in a 3-year period (2010-2013) has been analyzed. A total of 356,605 livestock including 265,692 sheep and 90,913 goats were slaughtered in the 3-year period and overall 39,613 (11.1 %) livers were condemned. Fascioliasis and dicrocoeliosis were responsible for 6.3 and 4.8 % of total liver condemnations in this period, respectively. Fasciola spp. and D. dendriticum infection in sheep (7.1 and 5.6 %, respectively) were considerably higher than goats (3.9 and 2.6 %, respectively). The annual prevalence rates showed a significant decline in the fasciolosis and dicrocoeliosis infection in goats (p \ 0.001). Data showed significant seasonal pattern for distomatosis in sheep and goats (p \ 0.001). Liver condemnations due to fasciolosis were prevalent in sheep and goats slaughtered during spring and autumn, respectively, whereas dicrocoeliosis were common in spring season for both sheep and goats. This survey provides baseline data for the future monitoring of these potentially important parasitic infections in the region.

A retrospective survey of liver flukes in livestock based on abattoir data in Kermanshah, west of Iran

“…The prevalence of liver fluke infections recorded in the present study was generally lower than those reported from other regions of Iran including Guilan (Daryani et al 2006), Mazandaran (Moghaddam et al 2004), Khouzestan (Sahba et al 1972), Lorestan (Ezatpour et al 2014), Ardabil (Saffarbani 1999), Fars (Ansari-Lari and Moazzeni 2006), Shahr-e Kord (Manouchehehri Naini and Bagheri 2000) and Tehran Provinces (Khanjari et al 2012).…”

“…Based on the literature, there are numerous reports of fasciolosis and dicrocoeliosis from different countries in Asia such as Iraq, Pakistan, Turkey, Saudi Arabia, Tunisia, Bangladesh, India, China, Japan, Korea and also many parts of Iran (Ezatpour et al 2014).…”

Gastrointestinal Helminthic Challenges in Sheep and Goats in Afro-Asian Region: A Review

“…The incidence of dicrocoeliosis in sheep and goats varied from 3.63-20.0 and 2.6-5.0 percent respectively ( Khajuria et al, 2013;Khanjari et al, 2014;Godara et al, 2014;Ezatpour et al, 2015;Tan et al, 2017). Nevertheless, there were reports of 32 percent prevalence in goats from India (Lone et al, 2012).…”

Animal health and disease monitoring in the abattoir

“…Khoramian et al (2014) found a prevalence of 3.28 % in central Iran and calculated a considerable economic loss. Ezatpour et al (2014) studied the prevalence of liver fluke in the abattoirs of Lorestan in Iran. They found a prevalence of 7.1 % overall in sheep and goats, with seasonal variation, whereby most condemnations were found in spring and autumn.…”

“…Among the diseases that are considered relevant in this context, several zoonotic diseases as well as epidemic, often notifiable, diseases can be mentioned (EFSA 2011, EFSA 2012, EFSA 2013a, EFSA 2013b. Apart from that, there are a number of diseases that are neither epidemic nor zoonotic, but highly relevant for animal husbandry or on-farm health and welfare (MacGillivray et al, 2013, Ezatpour et al, 2014.…”
