Intermittent leaching of copper from copper based fungicide through a saturated soil profile

Journal of Soil Science and Environmental Management

J. Soil Sci. Environ. Manage.

Copper is a micronutrient required for plant growth. However, it can have negative effect on plant growth if the concentration is too high. The aim of this study was to examine copper concentrations of leachate from soil columns treated with copper based fungicide. A 2 × 4 factorial arrangements consisting of two soil types (0 to 60 cm sample depth) and four rates of copper based fungicide concentrations (0, 1.88, 3.75 and 7.50 g/L ) was used... Read more

Extended-spectrum β-lactamase production and antimicrobial resistance in Klebsiella pneumoniae and Escherichia coli among inpatients and outpatients of Jimma University Specialized Hospital, South-West, Ethiopia

African Journal of Microbiology Research

Afr. J. Microbiol. Res.

Extended spectrum β-lactamases (ESBLs) have emerged as a major threat worldwide with limited treatment options. The prevalence of ESBL producing Escherichia coli and Klebsiella pneumoniae strains largely remain unknown in Ethiopia. The study was aimed at determining the occurrence of extended spectrum β-lactamase-producing E. coli and K. pneumoniae among inpatient and outpatient settings, their antimicrobial resistance profile and...

Alternatives for remediation and decontamination of soils from Brazil

African Journal of Agricultural Research

Afr. J. Agric. Res.

The aim of this work is to identify the main sources of contamination of soils, their effects on organisms also presenting alternatives for remediation and decontamination of these contaminated environments. The soils have in their composition organisms that are naturally present, as well as the presence of contaminants in increasing proportion when compared to the world industrialization and modernization of agriculture; therefore, increase in...
