[Effect of ultrasound on Eimeria tenella (Coccidiida, Eimeriidae)].
Ultrasonics (frequency--20 kHz intensity--11.9 w/cm2 and external lateral surface--1.88 cm2) can annihilate for 8 minutes from 90 to 100% of non-sporulated and for 16 minutes 99.5 to 100% of sporulated oocysts of E. tenella maintained in 10ml suspension plunged into a bath with ice. The destruction rate of oocysts depends on the duration of the ultrasonics effect and the increase of its intensity. It should be noted that the increase in intensity is more effective in this respect than the extension of ultrasonics effect.
