Neorickettsia risticii is an obligate intracellular bacterium of the trematodes and mammals. Horses develop Potomac horse fever (PHF) when they ingest aquatic insects containing encysted N. risticii-infected trematodes. The complete genome sequence of N. risticii Illinois consists of a single circular chromosome of 879 977 bp and encodes 38 RNA species and 898 proteins. Although N. risticii has...

Bovine fasciolosis is a parasitic disease of cattle caused by trematodes usually Fasciola gigantica and Fasciola hepatica in the tropics. The members of this genus are commonly known as liver flukes. The life cycle of these trematodes involves snail as an intermediate host (IH). The disease is found in vast water lodged and marshy grazing field condition anticipated to be ideal for the propagat...

To know the prevalence of heterophyid trematodes among inhabitants of a southern coastal village, i.e., Sacho-ri, Gangjin-gun, Jeollanam-do (Province), 82 stool samples were examined on helminth eggs and protozoan cysts using Kato-Katz and formalin-ether sedimentation techniques. Total 33 people (40.2%) were positive for trematodes (Heterophyes nocens 15 people, Pygidiopsis summa 3, Metagonimus...

The occurrence of trematodes within the gastropod Hydrobia ulvae was studied in two areas (a Zostera noltii bed and a eutrophic area) in the Mondego Estuary, Portugal. The aim was to assess trematode infections across snail age classes, as well as to investigate any influence of parasitism on the shell shape and size of these gastropods. In the Z. noltii bed, infection occurred in snails with s...

Food-borne trematodes constitute a family of lung, liver and intestinal flukes that have parasitized mankind and domesticated animals since the distant past. In the modern global village, food-borne trematodes present a daunting challenge of infection with severe morbidity, despite being highly neglected as causes of disease. Urbanization is the population shift from rural to urban centers, as ...

This study aimed to investigate the infection status, worm development, and phylogenetic characteristics of the intestinal trematode, Stellantchasmus falcatus. The metacercariae of S. falcatus were detected only in the half-beak (Dermogenus pusillus) out of the 4 fish species examined. Their prevalence was 90.0%, and the intensity of infection was 919 metacercariae on average. Worms were recove...
