Nodular gill disease (NGD) is an infectious condition characterized by proliferative lesions leading to respiratory problems, oxygen deficiency and mortality in fish. Globally, NGD primarily impacts freshwater salmonids intensive aquaculture systems. In recent years, numerous outbreaks of severe have affected more than half the larger rainbow trout (Oncorhynchus mykiss) farms Switzerland, mainly during spring early summer. Mortality has reached up 50% cases where no treatment was...
ABSTRACT Nodular gill disease (NGD) is a serious proliferative condition that affects farmed salmonids, particularly in Europe. While the cause of NGD remains unknown (and maybe multifactorial), various amoebae are often isolated from gills affected fish and can some cases be seen associated with lesions by histopathology. The present study aimed to quantify abundance different amoeba species directly rainbow trout healthy controls. An 18S rRNA amplicon metagenomic approach was employed...
