Stool samples from 409 pre-school and school students, living in six villages of the Cajabamba and Condebamba districts, Cajamarca, Perú, were examined using wet preparations and Lumbreras' method, looking for Paragonimus eggs. Fecal and sputum samples from two children (0. 5%) of 6 and 8 year-old showed eggs of Paragonimus. One hundred and twenty freshwater crabs, Hypolobocera chilensis eigenm...

Ten polymorphic loci were isolated and characterised from the intertidal New Zealand trematode Curtuteria australis. This common parasite manipulates the burrowing behaviour of its abundant bivalve host Austrovenus stutchburyi, with cascading impacts on the biodiversity of intertidal communities. Observed heterozygosities of the 10 loci ranged from 0.500 to 0.905, and three to 14 alleles were d...

Diplostomum is a taxonomically problematic genus of trematodes, with many members harmful at the metacercarial stage to fish in aquaculture. We found metacercariae eye vitreous humor rudd, Scardinius erythrophthalmus; bleak, Alburnus alburnus; and roach, Rutilus rutilus, Karelia (Russia) identified them as numericum based on combination morphological ecological data. Previously, D. was thought ...

Liver fluke infection caused by O. viverrini remains a major public health problem in many parts of Southeast Asia including Thailand, Lao PDR, Vietnam and Cambodia (IARC, 1994; Kaewpitoon et al., 2008b; Sripa et al., 2010; Sitthithaworn et al., 2012; Kaewpitoon et al., 2015a). Infection is acquired by ingestion of undercooked cyprinoid’s fish harboring infective metacercariae (Kaewkes 2003). L...

D icrocoelium dendriticum is the most widespread liver fluke in cattle and sheep in Italy [1]. Adult forms live in the gall bladder and bile ducts of their final hosts (ruminants). Eggs are passed in faeces and ingested by land snails which excrete cercaria in mucous balls, which are eaten by ants. Infestation usually occurs by ingestion of ants that carry metacercariae by animals and occasiona...

Pleurolophocercous cercariae emerged from naturally infected Melanoides tuberculata from Minas Gerais State, Brazil, were used to perform experimental infection of laboratory-reared Poecilia reticulata. Mature metacercariae were obtained from the gills of fishes and force-fed to Mus musculus. The adult parasites which recovered from small intestines of mice were identified as Centrocestus formo...
