[Application value of a dynamic automatic identification system in miracidium hatching test].

OBJECTIVE

To evaluate the value of a dynamic automatic identification system in routine miracidium hatching test with nylon gauzes.

METHODS

Different quantities of fresh eggs were added to bovine fecal samples and divided into the low-infection group, medium-infection group and high-infection group, while the bovine feces without eggs served as negative controls. The detection efficiency and accuracy were compared between the identification system and manual detection in different groups.

RESULTS

The identification system can automatically identify miracidium. The detection rate and efficiency of miracidium in bovine fecal samples were both higher by using the identification system than by manual detection. Notably in the low-infection group, the identification system had a significantly higher rate of detection of miracidium than manual detection (χ = 10.769, = 0.002). The identification system completed the detection of bovine fecal samples in the field within 1 min.

CONCLUSIONS

The dynamic automatic identification system may effectively improve the detection efficiency and accuracy of routine miracidium hatching test with nylon gauzes, and it may replace manual detection to be used in the field schisotsomiasis examinations and related researches.
