Artemia spp., a Susceptible Host and Vector for Lymphocystis Disease Virus.

ABSTRACT: Different developmental stages of Artemia spp. (metanauplii, juveniles and adults) were bath-challenged with two isolates of the Lymphocystis disease virus (LCDV), namely, LCDV SA25 (belonging to the species Lymphocystis disease virus 3) and ATCC VR-342 (an unclassified member of the genus Lymphocystivirus). Viral quantification and gene expression were analyzed by qPCR at different times post-inoculation (pi). In addition, infectious titres were determined at 8 dpi by integrated cell culture (ICC)-RT-PCR, an assay that detects viral mRNA in inoculated cell cultures. In LCDV-challenged Artemia, the viral load increased by 2-3 orders of magnitude (depending on developmental stage and viral isolate) during the first 8-12 dpi, with viral titres up to 2.3 × 102 Most Probable Number of Infectio
