The tapeworm, Spirometra erinaceieuropaei, was 1cm long and it had travelled 5cm from the right side of the brain to the left when it was removed by doctors.

It causes sparganosis – inflammation of the body’s tissues, which can lead to seizures, memory loss and headaches. It is thought people become infected by consuming tiny infected crustaceans from lakes, eating raw meat from reptiles and amphibians and by using frog poultice (a Chinese remedy for sore eyes).
Effrossyni Gkrania-Klotsas, study author from the Department of Infectious Disease, Addenbrooke’s NHS Trust, said, “We did not expect to see an infection of this kind in the UK, but global travel means that unfamiliar parasites do sometimes appear.”

The man has recovered from the operation and is well and scientists have now been able to discoverer the genetic secrets of the worm, offering new opportunities to diagnose and treat the parasite.
Hayley Bennett, first author of the study from the Wellcome Trust Sanger Institute, said, “The clinical histology slide offered us a great opportunity to generate the first genome sequence of this elusive class of tapeworms. However, we only had a minute amount of DNA available to work with just 40 billionths of a gram. So we had to make difficult decisions as to what we wanted to find out from the DNA we had.”

Researchers are now able to diagnose the worm through MRI scans, but more work is needed to identify its vulnerabilities. They also said the information gained can be matched with their work in global travelers infection, to give a better insight into what infections people can get in specific destinations.

Matt Berriman, senior author and member of Faculty of the Sanger Institute, said, “For this uncharted group of tapeworms, this is the first genome to be sequenced and has allowed us to make some predictions about the likely activity of known drugs. The genome sequence suggests that the parasite is naturally resistant to albendazole, an existing anti-tapeworm drug. However, many new drug targets that are being explored for other tapeworms are present in this parasite and could offer future clinical possibilities.”
