Tapeworms develop in the small intestine. Adults attach to the intestinal mucosa. Adult tapeworms may grow to over 10m in length and may constitute of over 3,000 proglottids which contain sets of male and female reproductive organs, allowing for high fecundity. Eggs appear in the faeces 5–6 weeks after infection. D. latum tapeworms are the longest and typically reach a length of 4-15m, but may grow up to 25m in length within the human intestine. Growth rate may exceed 22 cm/day. D. latum tapeworms feature an anterior end (scolex) equipped with attachment grooves on the dorsal and ventral surfaces. Host-parasite interactions<unk>  is postulated to cause changes in neuromodulator concentrations in host tissue and serum. D. latum infection has been shown to cause local changes in the host, leading to altered GI function (including motility) via neuroendocrine modulation.<unk>  causes mast cell and eosinophil degranulation, leading to pro-inflammatory cytokine release.
