Poultry colibacillosis causes several diseases that can cause great economic damage to poultry herds. Escherichia coli (E. coli) is a prominent member of this family, is known as one of the bacteria that pollutes the environment. Today, antibiotics and disinfectants are used to prevent a variety of diseases. However, due to inappropriate consumption, as well as incomplete duration of treatment, antibiotic-resistant bacteria have emerged. Due to their small size and high surface-to-volume ratio, nanoparticles have particle inhibitory properties and therefore have many cell-killing effects that can be used as antibacterial, fungal and viral agents. In this study, the antibacterial effects of cadmium sulfide nanoparticles were investigated by chemical and microwave precipitation methods in Escherichia coli bacteria isolated from poultry. For this purpose, Escherichia coli bacterial samples were collected from poultry clinics in Tabriz in May and June 2016 .Synthesized cadmium sulfide nanoparticles and Identified by XRD, UV and SEM analysis were exposed to cultured E. coli by both precipitation and microwave methods. Results were determined based on the minimum amount of MBC bactericidal and the minimum inhibitory concentration of MIC. The MIC was 1.653% and the MBC was 2.051%, the MIC was 2.051% and the MBC was 1.653%. The results of this study showed that cadmium sulfide nanoparticles have good antimicrobial effects on Escherichia coli; however, no significant difference was observed between the synthesis method of these nanoparticles for bactericidal and bacteriostatic effects.
