Effect of Radiofrequency Radiation from Telecommunication Base Stations on Microbial Diversity and Antibiotic Resistance

We aimed to investigate the effects of radiofrequency radiation from telecommunication on bacteria diversity and antibiotic sensitivity of surrounding bacteria micro-flora. In all cases of bacteria isolated, results indicated that radiation majorly influences and selected bacteria of specific morphology (rod-like, gram positive and spore formers) belonging to the genera Bacillus , Clostridium , Corynebacterium and Sporosarcina . Spore formation have been associated with prevention of DNA damage, this suggest that radiation may imposes stress detrimental to various non-spore forming, gram negative bacteria of nonrod morphology. The antibiotic resistance pattern indicated resistance above 50% in three of the ten common antibiotics tested with the highest of 96% recorded against zinnacef, followed by amoxicillin (70%) and ampiclox (56%). The highest resistance recorded was attributed to Bacillus spp while lowest resistance was recorded in Corynebacterium. The two largest groups of isolates; Bacillus and Clostridium have been reported as human pathogens and found to be multidrug resistant.
