Nanoparticles against resistant Pseudomonas spp

Pseudomonas spp. collected from areas where human regularly comes into contact with were tested for their susceptibility to antibiotics. Twenty-nine samples were collected and screened for Pseudomonas spp. Of the nine isolated strains Pseudomonas spp. six were resistant to antibiotics. A few were used for an antimicrobial study on the interaction with silver and zinc oxide nanoparticles individually and as a mixture. A mixture of silver and zinc oxide nanoparticles showed synergy against resistant Pseudomonas spp. •Antibiotic resistant Pseudomonas spp. collected from areas where human regularly comes into contact with.•Antimicrobial assay on antibiotic resistant Pseudomonas spp. using colloidal NPs killed them at the range of 15–30 ppm.•A synergetic antimicrobial effect of colloidal Ag and ZnO NPs on kanamycin resistant Pseudomonas spp. was observed.
