Objective:
To develop a dynamic automatic identification system (device) of Schistosoma japonicum miracidia to achieve the automatic detection and improve the detection rate and efficiency of schistosome miracidia.
Methods:
The dynamic automatic identification system (device) of S.japonicum miracidia was composed of an optical stereoscope, a digital camera, dynamic automatic tracking recognition software, and a computer. Under different conditions, the detection rates and efficiency of the system were compared with those of five professional persons.
Results:
The basic function of the system was to identify, label and warn the miracidia of S. japonicum, and the records could be saved automatically. The laboratory tests showed that the missing rate of the system was 0. The total consistent rates of the manual detection were 74.67% and 66.67% in the condition with and without water bug, while the total consistent rates of the system were 100.00% and 96.67%, respectively (χ2 = 9.634, 11.081, both P < 0.01) .
Conclusions:
The system is much superior to manual detection in the accuracy and speed, and the system could completely replace the manual detection. Therefore, the system could be used in the field and basic research of schistosomiasis.
