You can help!Add a definitionRecently laboratory studies have attempted to study more realistictoxicanteffects on cercarial survival by utilising contaminated material collected from polluted field sites.From theCambridge English CorpusFor example, recent studies have examined the potential for use of ant semiochemicals as termite repellents and toxicants.From theCambridge English CorpusDuring the mark-recapture studies, colonies were not treated with anytoxicant.From theCambridge English CorpusThe 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 CorpusA number of studies have noted that exposure of a host to atoxicantmay affect the physiology of trematodes residing in their tissues.From theCambridge English CorpusAll studies reported a general trend of a decrease in cercarial survival with increasingtoxicantconcentration.From theCambridge English CorpusData on the infectivity oftoxicant-exposed metacercariae is limited to species that form free-living cysts.From theCambridge English CorpusDespite the voluminous literature devoted to this subject, intraspecific comparisons amongtoxicantresistance genes are rare.From theCambridge English CorpusOnly after the mark-recapture experiments were finished, colonies were treated with different toxicants.From theCambridge English CorpusThe 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 CorpusThese studies have demonstrated a number of important physiological factors which influence parasite transmission undertoxicantexposure.From theCambridge English CorpusThese authors considered that exposure to both parasite andtoxicantmay have induced fish to abort their pregnancies.From theCambridge English CorpusThe effects of toxicants on cercarial infectivity have been extensively studied.From theCambridge English CorpusRespiration can also be seriously compromised intoxicantexposed infected snails.From theCambridge English CorpusThe duration and activity of the movement of cilia were significantly reduced with increasing temperature ortoxicantconcentration.From theCambridge English CorpusAttention 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 CorpusIt 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 CorpusMorley et al. (2002 a) reported that different species of target hosts may have differing susceptibilities totoxicant-exposed cercariae.From theCambridge English Corpus
