TL;DR: Evidence that HSMI is associated with infection with piscine reovirus (PRV) is provided, and measures must be taken to control PRV not only because it threatens domestic salmon production but also due to the potential for transmission to wild salmon populations.

TL;DR: The development and first validation of a TaqMan minor groove binder (MGB) real-time polymerase chain reaction (RT-PCR) method for quantitative and highly specific detection of Aphanomyces astaci, the causative agent of crayfish plague is presented.

TL;DR: An extensive evaluation of some promising chemistries: sequence-unspecific DNA labeling dyes (SYBR green), primer-based technologies (AmpliFluor, Plexor, Lux primers), and techniques involving double-labeled probes, comprising hybridization (molecular beacon) and hydrolysis (TaqMan, CPT, LNA, and MGB) probes, based on recently published experimental data.

TL;DR: It is suggested that the lacustrine P. aciculiferum and the marine-brackish S. hangoei diverged very recently, after a marine–freshwater transition that exposed the ancestral populations to different selective pressures, indicating a significant role of natural selection in the divergence of free-living microbes, despite their virtually unrestricted dispersal capabilities.

TL;DR: In this article, the authors used high throughput sequencing on heart samples from natural outbreaks of Cardiomyopathy syndrome (CMS) and from fish experimentally challenged with material from fish diagnosed with CMS.
