Antimicrobial Activity of Gold Nanoparticles and SWCNT-COOH on Viability of Pseudomonas aeruginosa

Abstract

Pseudomonas aeruginosa is a prevalent, opportunistic, gram-negative bacterium that infects immunocompromised individuals, frequently causing hospital-acquired and community-acquired infections. Total of 220 specimens were collected from different clinical sites included burns, ears, wounds, urinary tract, respiratory tract.

This study found that (25) isolates belong to Pseudomonas, where six isolates (24%) were obtained from wounds, nine isolates (36%) from burns, four isolates (16%) from ear infections, two isolates (8%) from urine and four isolates (16%) from respiratory infections. And in this study the effect of gold nanoparticles and single walled carbon nanotubes on the growth had tested. Results showed that the single walled carbon nanotube has a greater effect on the growth of Pseudomonas aeruginosa after exposure to the different concentrations of the single walled carbon nanotube for 24hr and 48hr.
