ABSTRACT

 

Noomi BS, Jaffar NA, Abdullwahab MH., Effect of titanium dioxide, zinc oxide and silver nanoparticles on growth of resistant bacteria isolated from wound infections in sheep, Onl J Vet Res., 22 (8):638-644, 2018. Authors report effect of titanium dioxide (TiO2), Zinc oxide (ZnO) and silver (Ag) nanoparticles (NP) on growth of multidrug resistant bacteria isolated from wound infections in sheep. Bacteria were tested against oxytetracyclin, cephalosporin, chloramphenicol, trimethoprim, ampicillin and ceftazidime for resistance and inoculated on blood, MacConkey's, chocolate, and mannitol agars. Of 59 wounds, 86.4% were infected by Pseudomonas aeruginosa (32%), S aureus (25%), E coli (20%), Klebsiella spp (13%) and Proteus mirabilis (9.8%). Minimum inhibitory concentrations for Ag NP ranged 10-60 g/ml, ZnO 40-60 g/ml and TiO2 20-40 g/ml with inhibition zones of 20-34mm, 14-36mm and 18-38mm, respectively.

 

Keywords: Nanoparticles, wound infection, MIC, TiO2 , Zno, Ag, multidrug resistant bacteria.
