Infection with Paryphostomum sufrartyjex (synonyms : Artyfechinostomum surfrartyfex; Euparyphium malayanum; Eclmiostoma sujrartyfcx) is extremely rare in human beings and to our knowledge this is the first case recorded in South India. The first report of human infection with this worm was reported by Lane in 1915. Bhalerao, in 1931, recovered this fluke from a pig in Bengal and worked out its ...

BACKGROUND The World Health Organization aims for complete morbidity control of fishborne zoonotic trematodes (FZT) in endemic areas by 2020. The main intervention tool for achieving this goal is regular use of preventive chemotherapy by offering praziquantel to those at risk in endemic areas. The purpose of this study was to investigate the effectiveness of preventive chemotherapy to control F...

1. Animal malformations engender wide public and scientific concern because of associated environmental health risks. This is highlighted by increased incidence of limb malformations in amphibians associated with trematode infections and disturbance. Malformations may signal new emerging disease threats, but whether the phenomenon is broadly applicable across taxa, or has population-scale impac...

The interactive effects of ocean acidification (OA) and parasitic infection have the potential to alter the performance of many marine organisms. Parasitic infection can affect host organisms’ response to abiotic stressors, and vice versa, while the response of marine organisms to stressors associated with OA can vary within and between taxonomic groups (host or parasite). Accordingly, it seems...

Charlie's Pond (North Carolina) harbors a diverse community of trematodes that infect the planorbid snail Helisoma anceps. Research at the Pond began in 1984 and serves as a foundation on which to investigate long-term changes in trematode communities. In 2002, 2005, and 2006 average size and fecundity of H. anceps were calculated each month, and seasonal trends analyzed with randomization test...

The occasional occurrence of high frequencies of limb abnormalities, including extra limbs, in natural populations of amphibians has long been a puzzle. In this paper we report the discovery of a population in which such limb abnormalities appear to be caused by a parasitic flatworm (trematode) that uses amphibians as intermediate hosts. The cercarial larval stage of the trematode attacks amphi...
