Development and application of the MIRA and MIRA-LFD detection methods of Spiroplasma eriocheiris.

The tremor disease (TD) caused by Spiroplasma eriocheiris is the most destructive disease of the Chinese mitten crab, Eriocheir sinensis. This study attempts to construct Multienzyme Isothermal Rapid Amplification (MIRA), a quick and simple nucleic acid amplification method that operates at room temperature. Based on the gene sequences of S.

The Eriocheir sinensis calcium/calmodulin-dependent protein kinase II activates apoptosis to resist Spiroplasma eriocheiris infection.

Calcium/calmodulin-dependent protein kinase II is a downstream mediator of calcium signalling and participates in the regulation of various cellular physiological functions. In previous studies, the expression of Eriocheir sinensis CaMKII (EsCaMKII) was significantly decreased in the thoracic ganglion after Spiroplasma eriocheiris infection, as shown using TMT-based quantitative proteomic analysis; however, the specific functions of EsCaMKII are still unclear. In this study, the full-length cDNA of EsCaMKII was 3314 bp long, consisting of a 1605 bp open reading frame encoding a protein of 535 amino acids, including a 258 aa serine/threonine protein kinase catalytic domain (EsCaMKII-CD).
