ABSTRACT The present study was conducted to assess the effect of Nd:YAG laser on
L eis h m a nia d o n o v a ni
promastigotes. L. donovani promastigotes exposed to Nd:YAG laser (wavelength 1060 A°) in 500, 1000 and 1500 pulse between each pulse and another 6 second in comparison to the control ( L . d o n o v a ni
promastigotes without exposure to Nd:YAG laser. The effect of Nd:YAG laser on the viability of L. donovani
promastigotes was measured using the colorimetric MTT assay and the percentage of viability was counted. L. donovani viable cells were decreased with long exposure to Nd-YAG laser. Nd:YAG laser was effective in killing most of L. donovani promastigotes, and the remaining were devoid flagellum that may lost their ability to cause infection.
