Following the publication of the original article [1], we were notified that:

  1. 1.

    The description of Fig. 2 was incorrect:

    • This image shows "an amphipod crustacean of the species E. verrucosus densely covered with an overgrown colony of parasitic ciliates. Ciliates living on weakened crustaceans are capable of forming vast colonies resembling a "fur coat"

    Should read:

    • This image shows "an amphipod crustacean of the species E. verrucosus densely covered with an overgrown colony of parasitic ciliates and unknown oomycetes or fungi. These organisms on weakened crustaceans are capable of forming vast colonies resembling a "fur coat"

  2. 2.

    The caption of Fig. 2 was changed from “Eulimnogammarus verrucosus, a species of crustacean endemic to the UNESCO World Heritage Site Lake Baikal, suffering from a parasitic ciliate infection. Attribution: Kseniya Vereshchagina” to “Eulimnogammarus verrucosus, a species of crustacean endemic to the UNESCO World Heritage Site Lake Baikal, suffering from a parasitic ciliate and unknown oomycete (water mold) or fungi infection. Attribution: Kseniya Vereshchagina”.

  3. 3.

    The affiliations of the 3rd and 4th authors had been swapped by mistake.

The original article has been corrected.
