OBJECTIVES: In light of the dramatic spread of Ebola virus in some parts of Africa and the 2014 outbreak in Nigeria, a study was conducted to evaluate bushmeat dealers’ knowledge and attitudes about zoonotic infections and the risk of transmission to humans. METHODS: A crosssectional survey was conducted in a community in Nsukka, southeast Nigeria. Hunters (n=34) and bushmeat traders (n=42) were interviewed. A semistructured questionnaire was used to generate the data. The Fisher exact test was used to evaluate the significance of differences between these groups. RESULTS: Only 11.8% of the hunters, as compared to 35.7% of the traders, had no knowledge of possible causes of zoonotic infections (p<0.05). However, 64.7% of the hunters, compared to 38.1% of the traders, were ignorant regarding the responsibility of public health personnel and veterinarians (p<0.05), and 76.5% of the hunters compared to 42.9% of the traders were ignorant regarding the existence of zoonoses in Nigeria (p<0.05). A statistically significant difference was also found between these groups regarding the risk of contracting an infection from ectoparasites (p<0.05). The attitudes of respondents towards zoonotic diseases did not differ significantly between the groups. CONCLUSIONS: The level of awareness about zoonotic diseases was low in this area, underscoring the need for interventions.

In this study we attempted to screen bacteria and fungi that generate electricity while treating wastewater using optimized double-chamber microbial fuel cell (MFC) system parameters. Optimization was carried out for five best exoelectrogenic isolates (two bacteria and three fungi) at pH values of 6.0, 7.5, 8.5, and 9.5, and temperatures of 30, 35, 40, and 45℃; the generated power densities were measured using a digital multimeter (DT9205A). The isolates were identified using molecular characterization, followed by the phylogenetic analysis of isolates with known exoelectrogenic microorganisms. The bacterium, Proteus species, N6 (KX548358.1) and fungus, Candida parapsilosis, S10 (KX548360) produced the highest power densities of 1.59 and 1.55 W/m<sup>2</sup> (at a pH of 8.5 and temperatures of 35 and 40℃) within 24 h, respectively. Other fungi― Clavispora lusitaniae, S9 (KX548359.1) at 40℃, Clavispora lusitaniae, S14 (KX548361.1) at 35℃―and bacterium― Providencia species, N4 (KX548357.1) at 40℃―produced power densities of 1.51, 1.46, and 1.44 W/m<sup>2</sup>, respectively within 24 h. The MFCs achieved higher power densities at a pH of 8.5, temperature of 40℃ within 24 h. The bacterial isolates have a close evolutionary relationship with other known exoelectrogenic microorganisms. These findings helped us determine the optimal pH, temperature, evolutionary relationship, and exoelectrogenic fungal species other than bacteria that enhance MFC performance.

African Traditional Fermented Foods and Probiotics
Kingsley C. Anukam,Gregor Reid 한국식품영양과학회 2009 Journal of medicinal food Vol.12 No.6
African traditional fermented foods remain the main source of nutrition for many rural communities in Africa. Although lactic acid bacteria are integral to many of these foods, little is known about the specific health benefits they confer or the properties of their strains. This mini-review explores the history of some African fermented foods and their microbial content and properties within the context of probiotic characteristics. Given the recent upsurge in probiotic research, recommendations are made on studies that could be performed with African fermented foods and their strains, with a view to improving the health of people in sub-Saharan Africa.

The development of rural areas is expected to be holistic covering all essential infrastructure. Community information centres (CICs) are agencies that should be part of the infrastructures for rural development. Unfortunately, these centres are hardly seen in rural communities in Nigeria, including Afikpo in Ebonyi State. Thus, this study was conceived to explore the perceptions of citizens towards the establishment of CICs in the locality. It adopted survey research method with questionnaire as instrument for data collection, which was self-developed and validated by experts with a pre-texted reliability index of 0.72. A total of 399 copies of the questionnaire were distributed, out of which 267 copies were properly completed, representing 67% and were used for analysis. Findings revealed that the citizens have overall positive perception towards establishing the CICs; they are also knowledgeable of the benefits of such centres. Furthermore, there are workable suggestions on ways of establishing, funding and managing CICs in Afikpo. In addition, about 65% of the respondents indicated interest to assist and support the funding and management of the CICs when established. However, the challenges of inadequate funding and support as well as the possible politics of where to site/locate the CICs in Afikpo, are likely impediments to the project. The study concluded that citizens have strong and positive disposition towards establishing CICs in Afikpo. The implications of such CICs for technological innovations were analysed. The study recommends, among others, that government should see the establishment of CICs as priority projects that would significantly contribute to the growth and development of rural communities in Nigeria; communities in Afikpo should explore self-help approach to development; and political representatives from Afikpo should take advantage of establishing CICs as constituency projects for the citizens.
