Studies on new infection route of pathogens to fish and shellfish via electrostatic interactions of positively charged heavy metal ions with negatively charged cells of the microorganisms

在这项研究中，我们通过实验揭示了鱼类或贝类通过食物生物体感染海洋双核病毒(MABV)的途径，该途径是通过用二价阳离子如Cd~(2+)、Zn~(2+)或Pb~(2+)喂养带负电荷的病毒颗粒和浮游生物细胞的离子凝聚来感染的。因此，重金属对环境的污染将在水产养殖环境中MABV感染循环的发展和鱼类疾病的暴发中发挥重要作用。

In this study, we experimentally revealed the development of an infection route via food organisms that fish or shellfish is infected with marine birnavirus (MABV) by feeding ion coagulations of negatively charged virus particles and plankton cells by bivalent cationssuch as Cd2+，Zn2+or Pb2+. Therefore, environmental pollution due to heavy metals will play an important role in development of the MABV infection cycle and fish disease outbreaks in aquaculture environments.
