Temporal variations in copper, iron and zinc levels in the periwinkle, Littorina littorea, were investigated to determine whether levels were affected by the sex of the organisms and/or by the presence of two species of trematode parasite. Significan

The parthenogenetic metacercarial stages of the gymnophallid trematode Cercaria margaritensis are found in the extrapallial cavity of the subtidal prosobranch mollusc Margarites helicinus. The primary metacercariae (M1) produce second-generation meta

The generally accepted perception of a parasite is invariably negative. They are considered degenerate, repulsive creatures that have appalling effects on their hosts and, as such, have been used as models by the film industry to represent the nature

Microphallus piriformes (Trematoda) is unusual in having only two hosts and no motile free-living stages. The intermediate host, the rough periwinkle, Littorina saxatilis, is present year-round on rocky shores and has a high parasite prevalence near

This study compares the metacercariae of a ‘pygmaeus’ microphallid discovered in Littorina saxatilis from the coast of Northern Ireland with the metacercariae of Microphallus piriformes and M. pygmaeus from the same species of gastropod mollusc f

SUMMARYThe behaviour of cercariae was recorded on video at 10, 20 and 30 °C and a combination of population and individual behavioural patterns studied. Initially cercarial populations were extremely active, individuals alternating between swimming

The cercariae of Cryptocotyle lingua have a brief but active life during which they do not feed. In order to maximize the probability of infection they must respond to a variety of host-related stimuli yet conserve their finite energy reserves by min

Maritrema arenaria is a microphallid trematode found in the intestines of marine wading birds. The metacercarial stage occurs in barnacles, Semibalanus balanoides. To date the cercarial stage had not been identified. Large numbers of M. arenaria meta

Scanning electron microscopy was used to compare the topography of Echinostoma trivolvis and E. caproni adults grown in golden hamsters for 15 days. The oral sucker of E. caproni was well-defined whereas that of E. trivolvis was not. Collar spines of
