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.
