The effect of electromagnetic waves on the growth of Entamoeba histolytica and Entamoeba dispar med./bio.

Published in: Saudi Med J 2005; 26 (9): 1388-1390

Aim of study (acc. to author)

To study the influence of electromagnetic irradiation of a GSM mobile phone (900 MHz) on the growth of the parasites Entamoeba histolytica and Entamoeba dispar (cysts or trophozoites, or both) in a 24-hour period.

Exposure setup
Exposure source
Chamber The mobile phone was placed in front of the medium tubes in an incubator (37?C) or in a plastic coated, heat insulated box (22?C).
Setup The mobile phones were turned to speech position for 60 seconds at 1-hour intervals during a total period of 24 hours.
Additional info Control groups were also divided into two temperature sub-groups but placed in another laboratory environment without mobile phones.

No parameters are specified for this exposure.

  • after exposure

Main outcome of study (acc. to author)

The number of E. histolytica and E. dispar decreased after electromagnetic field exposure at 37°C and room temperature (22°C) compared to the control group.
The results showed that exposure to electromagnetic field for a certain period of time may cause damage that can lead to death in single-cell organisms.
