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 µg/ml, ZnO 40-60 µg/ml and TiO2 20-40 µg/ml with inhibition zones of 20-34mm, 14-36mm and
18-38mm, respectively.
Keywords: Nanoparticles, wound
infection, MIC, TiO2 , Zno,
Ag, multidrug resistant bacteria.
