E-coil and he-ne laser beam

ABSTRACT

This paper deals with the effects of He-Ne laser beam [2=623.8 NM, p=5mw] with the effective dose at 60 min. Irradiance =20.7 10[]3 J/m[]2 on growth, morphology and antibiotic sensitivity of E. Coli [Type NCTC 1048] E. Coli cell number were decreased significantly at 60 minute irradiation. No dominant change in morphology is observed with an interesting change in antibiotic sensitivity
