“…Generally, with the similar fresh weight, H. diminuta accumulates up to 3-fold portion of ingested Pb dose compared with that of the host most loaded soft tissue (kidney) at both exposure levels. Therefore, our research clearly confirmed hyper-accumulative properties of H. diminuta for Pb, and the Hymenolepid tapeworm could serve as a suitable accumulative indicator of environmental pollution as introduced by Torres et al (2011) and Sures et al (2002, 2003 b ). Unlike field studies, we were able to determine the exact Pb-dose portion stored in fresh tapeworm tissue which was 0·015 and 0·037% after low and elevated exposure, respectively.…”

The effect of gastrointestinal helminths on Pb accumulation in the host body is ambiguous. A laboratory experiment with Rattus norvegicus/Hymenolepis diminuta model was conducted to determine Pb toxicokinetics in a terrestrial host-parasite system. The ET-AAS or ICP-OES techniques were used to determine Pb concentrations (CPb) in both tapeworms and host tissues (kidney, liver, bone, testes, muscle and intestinal wall). Concerning the entire host-parasite system, the highest CPb were detected in H. diminuta. Rat kidneys and bone were the only two tissues whose mean Pb levels were lower in parasitized animals than they were in non-infected subjects after both levels of exposure. At low Pb exposure, parasitization slightly changed the Pb toxicokinetics in the host body. However, with respect to tissue at the same exposure level, no significant differences were detected between the parasitized and non-parasitized animals and no significant correlations were found between CPb in tapeworms and those of host tissues. The results of this study indicate that H. diminuta does not protect rat from elevated Pb exposure even if tapeworm accumulates a higher portion of ingested Pb dose compared with that of the most Pb-loaded host soft tissue. The portion of Pb dose accumulated in H. diminuta correlates positively with parasite biomass.

The aim of this study was (i) to compare levels of accumulated heavy metals in the fox intestines with and without parasites. Moreover, our research also dealt with (ii) examination of the relationship between heavy metal content in fox intestines and between the presence of fox intestinal parasites. The intestines of 34 hunter-killed foxes were dissected to detect the occurrence of parasites. In 15 intestinal samples, parasitic intestinal helminths were found. Heavy metal content in small intestine tissue and in parasites was determined using atomic absorption spectrometry (AAS). The prevalence of parasites was significantly dependent on Cd content in the host’s small intestine (p < 0.01). To conclude, the authors suggest that parasites are sensitive to Cd levels; their prevalence in the intestines of the fox host decreases to zero with increasing Cd content.

Wildlife are frequently a neglected component of One Health; however, the linkages between the health of wildlife and human, domestic animal, and environmental health are clear. The majority of emerging zoonotic diseases are linked to wildlife, primarily driven by anthropogenic land changes. Despite this risk, wildlife have important links to people as environmental indicators, food security and safety, and through human livelihoods. This chapter will describe these linkages and demonstrate the need to understand these linkages through targeted surveillance and understanding the ecology of wildlife diseases. While the management of wildlife diseases presents a significant challenge, such practices will greatly improve the health of people, domestic animals, wildlife and the environment.
