In the present study, to further explore the etiology of HPND, the diseased crabs with HPND were collected from Yangcheng Lake Modern Agriculture Development Company, Suzhou, China, observation of the ultrathin section of tissues from the diseased crabs were observed with a transmission electron microscope and animal regression test were performed, moreover, toxic effect of avermectin and high pH water on crabs was also examined, the results indicated that HPND was not caused by virus or microsporidian and might be induced by water of high pH value and other environmental factors.

Ultrathin sections (40 to 50 nm) of tissue samples were cut using a Leica Ultracut UCT ultramicrotome (Leica Company, Solms, Gemany).
Semithin and ultrathin sections were obtained using an RMC MT-6000 ultramicrotome.
Ultrathin sections (5070 nm) were subsequently cut with a diamond knife on an LKB-11800 ultramicrotome (LKB Stockholm Sweden) and collected on 300- mesh copper grids.
After complete polymerization, the abscission zone tissues were obtained and made into ultrathin sections (50 nm).
