Background: Fascioliasis is a neglected zoonotic disease with worldwide distribution. Phylogenetic analysis of Fasciola species is critical because of their different epidemiology. Objectives: The current study aimed at identifying Fasciola spp. based on spermatogenesis and phylogenetic analysis of mitochondrial (ND1) gene. Methods: One hundred and fifty adults with fascioliasis were selected from the Eastern provinces of Iran, based on spermatogenetic ability, measurement criteria, and ITS (nuclear ribosomal DNA internal transcribed spacers) 1 gene restriction fragment length polymorphism (RFLP) pattern. Then, their genetic diversity indices and phylogenetic relationships were analyzed using mitochondrial DNA marker of Fasciola population spread in the East of Iran. Results: Aspermic F. gigantica was observed in the eastern part of Iran. Partial sequences of mtDNA showed new haplotypes in both species. Pairwise fixation index between different F. gigantica populations calculated from the nucleotide data set of ND1 gene were statistically significant and showed the genetic differences in pairwise population. Conclusions:The results of the study showed that F. hepatica, lives in this region of Iran, had different genetic structures compared with the other Fasciola populations in the world. Fasciola gigantica present in the East of Iran had different genetic structures, compared with the other Fasciola population, based on genetic index.

“…Fasciola hepatica has a cosmopolitan distribution, while F. gigantica is found in tropical regions of Africa and Asia. Thus, the two fasciolid species overlap in many African and Asian countries, although in such cases the ecological requirements of the flukes and their snail intermediate host are distinct (Ashrafi et al 2006). The presence of fasciolosis in Iran has long been known and its prevalence and economic significance has been reported by several researchers (Moghaddam et al 2004;Ansari-Lari and Moazzeni 2006;Ashrafi et al 2006;Borji and Parandeh 2010;Ghazani et al 2008;Oryan et al 2011;Khanjari et al 2014).…”

Although a review of available literature strongly suggests that fasciolosis exists in almost all parts of the country, but its prevalence among domestic animals is higher in the southern part of the country, whereas the number of reported human disease cases is significantly higher in the Northern provinces (Khanjari et al 2014).…”

“…Most of the published reports in Iran are from the central, southern and northern parts of the country and there was not any data about Fasciola and Dicrocoelium in the western Iran (Moghaddam et al 2004;Ansari-Lari and Moazzeni 2006;Ashrafi et al 2006;Borji and Parandeh 2010;Ghazani et al 2008;Oryan et al 2011;Khanjari et al 2014). Therefore this survey was designed to estimate the prevalence of liver flukes in abattoir populations of cattle, sheep and goats in the western part of Iran for the period 2008-2013.…”

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

A retrospective study was carried from 2008 to 2013 to estimate the prevalence of liver flukes in ruminants slaughtered at the abattoir of Kermanshah province, west of Iran. A total of 663,633 animals slaughtered in the 5-year period and totally 1.95 % of livers were condemned due to liver flukes. Fasciolosis were responsible for 0.8, 0.7 and 1.5 % of liver condemnations, whereas 1, 0.8 and 1 % of liver were condemned because of Dicrocoelium dendriticum infection in the sheep, goats and cattle, respectively. A significant difference in the prevalence of liver flukes were observed among studied animals (p \ 0.001) and the highest and lowest prevalence were detected in cattle and goats, respectively. Data showed significant seasonal pattern for distomatosis in sheep and goat (p \ 0.001). Liver condemnations due to fasciolosis were prevalent in sheep and goats and cattle slaughtered during winter, summer and autumn, respectively, whereas dicrocoeliosis were common in autumn season for sheep and cattle and in winter for goats. This survey provides baseline data for the future monitoring of these potentially important parasitic infections in the region.
