Schistosomiasis is an important zoonosis and some livestock especially cattle play a crucial role in disease transmission in endemic areas. In order to establish an effective diagnostic method for detecting Schistosoma japonicum infection in cattle, the gene encoding large hydrophilic domain of Sj23 (LHD-Sj23) was cloned and expressed in Escherichia coli as a fusion protein with GST tag. The purified rLHD-Sj23-GST was used as an antigen in an indirect enzyme-linked immunosorbent assay (iELISA). The sera samples collected from cattle experimentally infected with S. japonicum from week 0 to week 54 post-infection were examined by rLHD-Sj23-GST iELISA. Furthermore, 484 clinical sera samples collected from cattle in schistosomiasis epidemic and free areas in China were tested by this method with a positive rate of 18.4% and 3.44%, respectively. The findings from this study indicated the established iELISA is a useful method for diagnosing S. japonicum infection in cattle and could be used in serological surveys to map out the prevalence of this disease.

Cystic echinococcosis (CE) is a widely distributed zoonosis that is highly endemic in the Mediterranean basin. The disease represents a serious public health threat and causes economic losses. The parasite life-cycle involves dogs and ruminants as definitive and intermediate hosts; humans are accidently infected, causing serious clinical issues. Vaccination of ruminants and dog treatments represent the most efficient measures to prevent parasite transmission. The recombinant protein vaccine, EG95, has been used successfully in sheep vaccine trials against CE in several countries. In this study, we expressed the modified antigen, EG95NC-GST, in Escherichia coli for use as a vaccine against Echinococcus granulosus in ruminants. We tested three different media formulations for E. coli culture and established for each culture conditions for optimal levels of soluble EG95 expression. The results demonstrate that SOC and TB media provided high yields in cell density and EG95 protein expression. Purification of the recombinant protein with affinity chromatography (using FPLC) was also performed to increase the purity of the EG95NC--GST antigen.
