Characterization of Two Trichinella spiralis Adult-Specific DNase II and Their Capacity to Induce Protective Immunity.

ABSTRACT: Deoxyribonuclease II (DNase II) is a widespread endonuclease, which can degrade the DNA. Trichinella spiralis adult-specific DNase II-1 (TsDNase II-1) and DNase II-7 (TsDNase II-7) were identified in excretory-secretory (ES) or surface proteins of adult worm (AW) and intestinal infective larvae (IIL) using immunoproteomics with early infection sera. The aim of this study was to characterize the two T. spiralis DNase II enzymes and to investigate their role as potential vaccine candidate target molecules. The cDNA sequences of the two DNase II enzymes from 3 days old AWs of T. spiralis were cloned and expressed. The sequencing results showed that the complete cDNA sequences of the two DNase II enzymes were 1221 and 1161 bp long, and the predicted open reading frames enc
