Description
Ivica Králová-Hromadová and colleagues genotype tapeworm larvae in fish from a western Norwegian lake in a 2026 parasitology study. Two broad tapeworm species, Dibothriocephalus dendriticus and Dibothriocephalus ditremus, mature in fish-eating birds and use salmonids as intermediate hosts. Brown trout and Arctic charr from Lake Kalandsvatn carried larvae of both.
Microscope form plus a PCR test sorted 1,313 larvae. The count came out lopsided: 90.8 percent were D. ditremus, against 9.2 percent D. dendriticus, making this the first record of ditremus in the lake. Prevalence per fish followed the same order, reaching one hundred percent of charr for ditremus, and its infection intensities ran far higher, up to 221 larvae in a single trout. The authors attribute the dominance to feeding ecology and to the abundance of the fish-eating birds in which ditremus completes its life cycle. The study updates the lake's parasite map with molecular certainty.
