Add a definition Recently laboratory studies have attempted to study more realistictoxicanteffects on cercarial survival by utilising contaminated material collected from polluted field sites. From theCambridge English Corpus For example, recent studies have examined the potential for use of ant semiochemicals as termite repellents and toxicants. From theCambridge English Corpus During the mark-recapture studies, colonies were not treated with anytoxicant. From theCambridge English Corpus The impaired survival of infected molluscs in polluted conditions may be due to an alteration intoxicantaccumulation in infected molluscs compared to uninfected ones. From theCambridge English Corpus A number of studies have noted that exposure of a host to atoxicantmay affect the physiology of trematodes residing in their tissues. From theCambridge English Corpus All studies reported a general trend of a decrease in cercarial survival with increasingtoxicantconcentration. From theCambridge English Corpus Data on the infectivity oftoxicant-exposed metacercariae is limited to species that form free-living cysts. From theCambridge English Corpus Despite the voluminous literature devoted to this subject, intraspecific comparisons amongtoxicantresistance genes are rare. From theCambridge English Corpus Only after the mark-recapture experiments were finished, colonies were treated with different toxicants. From theCambridge English Corpus The relatively few studies on the effects of toxicants on miracidial infectivity to date have focused on the effects of short duration acute concentrations. From theCambridge English Corpus These studies have demonstrated a number of important physiological factors which influence parasite transmission undertoxicantexposure. From theCambridge English Corpus These authors considered that exposure to both parasite andtoxicantmay have induced fish to abort their pregnancies. From theCambridge English Corpus The effects of toxicants on cercarial infectivity have been extensively studied. From theCambridge English Corpus Respiration can also be seriously compromised intoxicantexposed infected snails. From theCambridge English Corpus The duration and activity of the movement of cilia were significantly reduced with increasing temperature ortoxicantconcentration. From theCambridge English Corpus Attention has thus begun to focus on other mechanisms of cercarial functional biology which may be better indicators of an increased vulnerability to toxicants. From theCambridge English Corpus It was concluded that this was due to an increase in the mortalities of the cercarial and metacercarial stages, which occurred with more frequency with increasing exposure to the toxicants. From theCambridge English Corpus Morley et al. (2002 a) reported that different species of target hosts may have differing susceptibilities totoxicant-exposed cercariae.
