Examining household possession and willingness to pay for the retreatment of ITNs with insecticides among local residences in a malaria endemic area.

Objective: To examine the household possession and willingness to pay for the retreatment of ITNs with insecticides among local residences in a malaria endemic area of Ethiopia.

Methods: A descriptive cross-sectional study was conducted between October 2008 and December 2008 using a pre-tested questionnaire in Azendabo town, Ethiopia. 246 household members were interviewed on the household possession and willingness to pay for the retreatment of ITNs with insecticides.

Assessment of siltation and nutrient enrichment of Gilgel Gibe dam, Southwest Ethiopia.

Gilgel Gibe hydroelectric power dam was located in the submerging part of the Addis Ababa, Jimma highway in Ethiopia which is about 55 km far from Jimma was constructed in 2004. A cross-sectional study was conducted during 2005 to assess the siltation and nutrient enrichment level of the dam. It was found from the study that siltation and nutrient enrichment were the major problems in this reservoir.

Characterization of Escherichia coli isolates from different fecal sources by means of classification tree analysis of fatty acid methyl ester (FAME) profiles.

Microbial source tracking (MST) methods need to be rapid, inexpensive and accurate. Unfortunately, many MST methods provide a wealth of information that is difficult to interpret by the regulators who use this information to make decisions. This paper describes the use of classification tree analysis to interpret the results of a MST method based on fatty acid methyl ester (FAME) profiles of Escherichia coli isolates, and to present results in a format readily interpretable by water quality managers.
