Table 3.

The zones of inhibition (mm) of AgNPs synthesized using aqueous and organic extracts of Z. zerumbet.

Sr. No. MDR Bacterial Strains Zone of Inhibition (mm) Means ± SD
ZZAE-Ag-NPs ZZEE-Ag-NPs
1 Enterococcus faecalis 19.33 ± 0.57 19.83 ± 0.57
2 Streptococcus mutans 17.83 ± 0.57 18.83 ± 0.57
3 S. aureus 13.83 ± 0.57 14.66 ± 0.57

Note: Plant extracts (ZZAE and ZZEE) did not show antimicrobial activity against MDR pathogen strains. MDR multidrug-resistant, ZZAE-Ag-NPs = AgNPs synthesized using aqueous extract of Z. zerumbet, ZZEE-Ag-NPS = AgNPs synthesized using organic extract of Z. zerumbet, ZZAE = Z. zerumbet aqueous extract, ZZEE = Z. zerumbet ethanolic extract. (Sr.No = Serial Number and Means ± SD = Mean ± standard deviation).
