OBJECTIVE: To develop a bionic animal skin and evaluate its detective effect of Schistosoma japonicum cercariae so as to provide a new technique for the monitoring of the schistosome susceptibility water body.
METHODS: A bionic animal skin was made with pigskin and the experiments were carried out for evaluating its detective effects of S. japonicum cercariae in laboratory and simulate fields, and at the same time, the sentinel mouse method was used as the control.
RESULTS: In the laboratory, the cercariae were found in 10-, 30-, 60-cercaria subgroups in the bionic animal skin group after 1 and 2 hours, but the cercariae were found only in the 60-cercaria subgroup in the sentinel mouse group. In the simulate fields, in the water body with 5 schistosome-infected Oncomelania hupensis snails, the cercariae were found in 2 bionic animal skin devices (2/4) and 3 bionic animal skin devices (3/4) after 2 hours and 4 hours respectively, and in the water body with 10 schistosome-infected O. hupensis snails, the cercariae were found in 4 bionic animal skin devices (4/4) and 3 bionic animal skin devices (3/4) after 2 hours and 4 hours respectively in the bionic animal skin group. In the the sentinel mouse group, in the above-mentioned water bodies (with 5 or 10 schistosome-infected O. hupensis snails), the cercariae were found in 2 sentinel mice (2/4) and 1 sentinel mice (1/4) after 2 hours and 4 hours respectively; and the cercariae were found in 2 sentinel mice (2/4) and 3 sentinel mice (3/4) after 2 hours and 4 hours respectively.
CONCLUSIONS: The bionic animal skin device can be used to detect the S. japonicum cercariae, and its sensibility and efficiency are superior to the traditional sentinel mouse method.
