Molecular markers link Vibrio cholerae hazards in the Akaki catchment to human sewage pollution. 0.6-20% of fecal coliforms in the rivers of the catchment had ESBL producing antibiotic resistance traits. Hazards were highest in the dry season when river water is used for irrigation. Read our paper in Science of the Total Environment.
Sometimes you find the opposite of your hypothesis. Despite of the river pollution from domestic, industrial, and commercial activities in Addis Ababa, higher metal levels were found in nails of residents living in the upstream rather than the downstream area of the Akaki river catchment. Excellent work led by Dr Dessie and colleagues in Ethiopia.
Excellent video clip from our collaborators in Ethiopia describing the water quality challenges in the Akaki River Basin.
We have assembled small equipment items into a water quality lab that fits into a suitcase. The suitcase lab enables 16S rRNA gene amplicon based characterization of millions of bacteria in water samples, almost anywhere in the world. A fantastic outcome of our collaboration with colleagues in Ethiopia.
