Molecular characterization of Fasciola hepatica from Sardinia based on sequence analysis of genomic and mitochondrial gene markers

Molecular evidence shows that the liver fluke Fasciola gigantica is the predominant Fasciola species in ruminants from Pakistan

“…(Ali et al, 2008), Japan (Itagaki et al, , 2005Ichikawa & Itagaki, 2010), Korea (Agatsuma et al, 2000), China (Huang et al, 2004;Liu et al, 2014) and Vietnam . A number of studies revealed singlespecies infections of F. hepatica, reported in Tunisia, Algeria and Italy (Garippa, 2009;Farjallah et al, 2013) and F. gigantica has been reported in India (Velusamy et al, 2006;Prasad et al, 2008;Raina et al, 2013) and Mauritania (Amor et al, 2011a). …”

Morphological and molecular identification of Explanatum explanatum in domestic water buffalo in Pakistan

“…However, confirmation of the true species identity of Paramphistomatidae flukes by morphological examination can be imprecise in all except the most experienced hands, while molecular speciation methods are seldom used. Fasciola hepatica is generally described as occurring in temperate regions (Farjallah S, 2013;Ichikawa and Itagaki, 2010) and Fasciola gigantica in tropical areas (Amor et al, 2011), but both species overlap in subtropical areas along with intermediate genotypes (Agatsuma T, 2000). F. gigantica is the predominant species in buffalo and cattle in the Punjab and Baluchistan provinces of Pakistan (Chaudhry et al, 2015), but co-infections with F. hepatica and F. gigantica and intermediate genotypes have been described in the same region (Agatsuma T, 2000;Huang et al, 2004;Ichikawa and Itagaki, 2010;Marcilla A, 2002;Rokni MB, 2010).…”

Molecular evidence for resurrection of Plesiochorus elongatus (Digenea: Gorgoderidae): An urinary bladder parasite of sea turtles

“…variants of the same species as ITS2 has been shown to vary between populations of trematode species, with haplotypes found to be associated with specific geographical locations [22,23,24,25]. However, the occurrence of genotypes from both the USA and Brazil in both sub-clade A and B supports strong separation of the two non-location specific lineages which appear to occur sympatrically.…”

“…There is genetic evidence of movement of loggerhead sea turtles from South East Asia, to South America and then up into the waters of North America [45]. The distribution of parasites is intimately linked to the movement of hosts[22,23,24]: given the global connectivity of loggerhead sea turtle populations, the occurrence of such sympatry in populations of P. cymbiformis and P. elongatus in the USA and Brazil is not surprising.…”
