Abstract

Escherichia coli belongs to the genus of Escherichia which can cause many diseases to humans including gastrointestinal diseases and appendicitis. The aims of study were to determine and evaluate the effects of infrared radiation on E. coli isolated from appendectomy.

In this study, we had 10 tubes contained known numbers of bacterial colonies in Nutrient broth. These tubes were irradiated by infrared from a source emits infrared at wave length700-1200nm with 50watt ans at different exposure times, constant energy rate.

The results showed that the number of E. coli bacterial colonies were significantly (P<0.01) decreased at each increasing in exposure time at constant energy rate. The number of E. coli bacterial colonies died in first tube after irradiation at 10min was 11 and in the seventh tube at 70min were 110. So, all bacterial colonies died at infrared radiation wave length 700-1200nm in 150watt within 70min. We concluded that the infrared radiation can kill E. coli bacteria by stimulating oxidation, breaking chemical bonds and producing free radicals.
