A natural phosphate electrode modified with antibiotic (amoxivillin) was employed for the detection and quantification of Staphylococcus aureus from aqueous solutions. The new electrode (AMX-NPE) revealed interesting electroanalytical detection of Staphylococcus aureus based on the adsorption of these bacteria onto antibiotic under open circuit conditions. The bacteria redox peaks were operated by square wave voltammetry in 0.1 mol/L NaCl solution. The response depends on the concentration of bacteria in the bulk solution as well as the parameters involved in the preconcentration, pH and the measurement steps
