Abstract

A process and apparatus for killing organisms in situ within a host by means of successive short-duration high-current-density pulses of electricity of alternately opposite polarity. These pulses are passed through the host and concomitantly the organisms for a period of a few seconds. The cellular structure of the host is not destroyed, nor is the temperature thereof appreciably elevated. The current is conveyed to the host from electrodes (3, 4) immersed with the host in a weak electrolyte (24). The pulses are formed by phase-controlled thyristors (5, 6).
