Therefore, this laboratory-based study aimed at determining enteric bacterial pathogens and their antibiotic-resistant patterns from the environmental sources in different regions of Ethiopia.Ī laboratory-based cross-sectional study was conducted by following the standard microbial culture and the Kirby-Bauer disc diffusion method for identification and AMR patterns of the enteric bacteria using a total of 180 environmental samples from January through June 2020.

Unfortunately, it is one of the missing topics on sustainable development goals (SDGs). Finally, it is the first report of siderophore-producing microorganisms from polluted soil of Callejón de Huaylas highlands, interestedly they displayed metabolic properties useful to enhance phytoremediation and biotechnology application.Īntimicrobial resistance (AMR) resulting in the most significant public health and economic threat. Medicago sativa seedlings inoculated with BEP17-Dm, BEP18-Dm, or BRU16-Sr showed more surviving percentage under in vitro culture in presence of Cd, Pb (0.5–1.0 mM), or Al (2.5–5.0 mM). BEP18-Dm produced higher concentration of IAA (53.42 μgml⁻¹) while six bacteria and all fungi strains produced a low concentration of auxins. subtilis BRU16-Sr exhibited higher solubilization index. Two bacteria and six fungi solubilized cadmium carbonate, while eleven bacteria and two fungi solubilized tricalcium phosphate, where P. All bacteria strains tolerated lead (2−8 mM) and eigth tolerated cadmium (1−6 mM) also all fungi tolerated lead (9−70 mM) and cadmium (3−10 mM). According to the 16S rDNA analysis, bacteria belong to Pseudomonas, Bacillus, and Achromobacter genera, whereas by ITS analysis fungi belong to Talaromyces, Hypoxylon, Tolypocladium, and Penicillium. It was selected 14 bacteria and 9 fungi strains by their iron and/or aluminum siderophore production trait, where BEP17-Dm showed higher production. Endophytic and rhizospheric microorganisms associated with six native plants adapted to heavy metal polluted soil from Punta Olímpica and Chahuapampa, located in Callejón de Huaylas mountains, were evaluated as potential candidates for technologies to clean polluted ecosystems.
