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. © JASE

Colonial Heritage, Identity-Building and Communication: English and Nigerian Languages in Biafra

The Biafran War (1967–1970) has often been called “the forgotten war”, yet it marked a watershed in the development of the Nigerian foreign policy, gave birth to the NGO Médecins sans frontières and its refugee camps taught foreign journalists the intercultural skills they were to use later to report on other African conflicts. While many books and scholarly articles have been written on the war, its use of languages and impact on post-war language policies have never really been considered. Using media bulletins compiled by the author between 1968 and 1970, data collected by French journalists and published in 1968–1969, memoirs published later by various people involved in the humanitarian efforts of the period and songs recorded by the Biafran Red Cross during the conflict, this chapter will reveal how war years confirmed language preferences built during the colonial period. It will show how the necessity to communicate both with the outside and within the Biafran enclave contributed to gradually shape language practices, and will consider the reasons behind that choice. It will finally confirm the huge emotional and psychological power mobilised by languages during the conflict
