Abstract: Microbial Fuel Cell (MFC) is a technology fed with microorganisms that mediate the conversion of chemical energy present in organic matter into electrical energy. MFC technology offers the potential to treat wastewater and generate power at the same time. In this research MFC was utilized to treat wastewater and generate bioelectricity. The wastewater sample was obtained from Dutse urban, Nigeria. MFC was run in fed batch mode for three cycles. Wastewater was treated by calculating the percentage removal of Chemical Oxygen Demand (COD). Voltage was measured using digital multimeter. Power and current density were calculated using ohms law. During wastewater analysis the MFC shows a reduction in COD by 82 % (Initial 680 ± 5 mg/L and final 120  ± 2 mg/L ). The highest voltage in first, second and third cycles were 178 mV, 196 mV and 183 mV respectively, Power density was 18.26 mW/m² and current density was 97 mA/m^2.. The result obtained in this study can contribute to improve understanding on wastewater treatment and bioelectricity generation using MFC.

Abstract: A study was carried out to determine the prevalence of intestinal helminths infestation among primary school pupils in Aba metropolis. A total of 100 stool samples were randomly collected from pupils of both sexes, aging 5 - 12 years old and examined using direct smear and formol-ether concentration technique. Twelve (12%) of the samples were found positive for intestinal helminths. The Intestinal helminths observed were Ascaris lumbricoides 7 (58.3%) and hookworm 5 (41.7%). Pupils in the age group 10 - 12 years old had the highest prevalence of 66.7% followed by  the age group 7 -9 years old (25%) the least was in age group 5 – 6 years (8.3%) .There was no significance association between age and the prevalence of infestation (p > 0.05). Females are more infested (66.7%) than males (33.3%). There was no association between gender and prevalence of infestation (p > 0.05). Also there was no significant difference on the prevalence of intestinal helminths among schools (p > 0.05), although Ogborhill primary school has the highest number of infestation (33.3%) while Living word Academy has the lowest number (8.3%). Pupils drinking sachet water had the highest infestation (83.3%) than those drinking borehole (16.7 %). There was a statistically significance association between the prevalence of infestation and the source of water (p < 0.05).Our study  shows that pupils carry moderate intestinal parasites burden and source of water had contributory effect on the prevalence of infestation. To reduce the prevalence of intestinal helminths in the area, school based deworming campaign; public health awareness programs and improved water supply of the populace are recommended.
