| Outline of Final Research Achievements |
Fish diseases are generally diagnosed by histological and/or molecular biological analysis following the observation by eyes. However, it is difficult to examine the whole body and clarify the localization of pathogens. Here, we investigated whether the recently developed transparent techniques such as Scale, SeeDB, ClearT and CUBIC are applicable to diagnosis of fish diseases.
CUBIC, which is modified from Scale was most effectively transparentized the fish body, and applicable to imaging of GFP and immunostaining. Furthermore, Aeromonas hydrophila labeled with DAPI could be visualized under a fluorescent microscope. Although DNAs were preserved in all transparent specimens and applicable to PCR, RNA was degraded by CUBIC due to containing basic aminoalcohols. On the other hand, RNA was highly preserved in organs treated with SeeDB or ClearT. Our results indicate that proper use of transparent techniques enable whole body diagnosis of the infectious disease in fish.
