Abstract

In this study, two aspects of the ultrastructure of white spot syndrome virus (WSSV) were identified: (i) The virus nucleocapsids were disassembled, and transmission electron microscopy (TEM) image analysis confirmed that the nucleocapsids were composed of stacked ring segments rather than the usual helix system, with each ring segment consisting of three rows of subunits linked by filaments. (ii) In addition, the morphological characteristics of virus self-assembly at different stages were observed, and two different enveloping morphologies were found, implying that the virion matures through two distinct envelopments. Thus, we propose a viral membrane assembly process for WSSV virion.

WHO estimates that half of all patients worldwide are non-adherent to their prescribed medication. The consequences of poor adherence can be catastrophic, on both the individual and population level.

Join our expert panel to discover why you need to understand the drivers of non-adherence in your patients, and how you can optimize medication adherence in your clinics to drastically improve patient outcomes.
