This brilliant colour is caused by IIV-31 (Isopod Iridescent Virus). I've been checking hundreds of pill bugs over several years for this unusual phenomenon and my persistence finally paid off! Sadly, this total colour change is usually the later stage of the virus; once a pill bug is this bright it generally doesn't have much longer to live. This should occur in any sizeable pillbug population so keep an eye out for it! @dlbowls @finatic @jaykeller @tiyumq @loarie @sambiology @glmory @cedric_lee

Summary[edit] Description: English: Transmission electron micrographs of FHM cells infected by Frog virus 3 (FV3). Upper left and right panels show typical virus-infected cells with nuclei (N) showing evidence of chromatin condensation, well-defined viral assembly sites (AS); intracytoplasmic paracrystalline arrays (asterisk), and virions budding from the plasma membrane (arrow). Lower left panel shows a virus-infected cell in which virions are scattered throughout the cytoplasm. Lower right panel is an enlargement of a viral assembly site showing virions in various stages of assembly. Full (A4 and A5) and empty (A3) viral particles are shown as well as two possible intermediates (A1 and A2) and two aberrant forms (C and E). The inset indicates membranes (arrows), possible originating from the ER, that play a role in virion morphogenesis. Date: 2015.

Summary[edit] Description: Since the mid 1990s, a type of virus known as a ranavirus has been taking a devastating toll on reptiles and amphibians -- especially turtles, frogs, toads and salamanders -- in more than 20 states across the U.S. Hundreds of thousands of these animals have died from the lethal virus and the disease continues to spread. Scientists are stepping up their efforts to better understand and combat the pathogen, and VOA's Zulima Palacio talked with some of them. Date: 13 April 2012. Source: http://youtu.be/pVYQK5WxGr8.

What is it that makes them turn blue? That's what I'd like the ID for!

Summary[edit] Description: English: Schematic diagram of Ranavirus replication. Virions enter cells by one of two possible routes and initial events in virus replication (early viral transcription and the synthesis of unit length genomes) take place within the nucleus. Viral genomes are subsequently transported into the cytoplasm where they are methylated and serve as templates for concatemer formation. Viral assembly sites contain viral DNA and a number of virus-encoded proteins and serve as the loci of virion formation. Newly synthesized virions are found free within the cytoplasm or within paracrystalline arrays, and, a minority, at least in vitro, bud from the plasma membrane and in the process acquire an envelope.
