Careful experimenters have shown that the electric current, either direct or alternating, has no direct destructive effect on bacteria. In a liquid medium the organisms may be attracted to or repelled from one or the other pole or may arrange themselves in definite ways between the poles (galvanotaxis), but are not injured. However, electricity through the secondary effects produced, may be used to destroy bacteria. If the passage of the electric current increases the temperature of the medium sufficiently, the bacteria will be killed, or if injurious chemical substances are formed (ozone, chlorine, acids, bases, etc.), the same result will follow (see Ozone, pp. 77 and 157).
