Resumo

Zinc sulfide (ZnS) nanoparticles powders were prepared using the sol-gelmethod at pH values of 5, 6, and 7. The samples were treated at 200 °C for 1 h.The X-ray diffraction (XRD) results showed that the samples have a cubic crystalstructure. The crystalline size decreased to 2.22 ± 0.6 nm at pH 7 due to an increase in the micro-strain. The higher lattice parameter value of ZnS is observedat pH 7 and reached a value of 5.38 ± 0.006 Å, close to bulk ZnS’s value of 5.4Å. The synergistic effect of as-prepared ZnS with chloramphenicol (C), Gentamycin (CN), and nalidixic acid (NA) antibiotics showed significantly decreasedgram-negative Salmonella typhi and gram-positive Bacillus cereus bacteria activityat pH 5 and 7. The calcinated ZnS has a good synergistic effect with NA andC antibiotics against S. typhi at pH 5 and 7. The B. cereus bacteria was sensitiveto the ZnS with CN antibiotic only at pH 5 and pH 7, with zone of inhibition(ZOI) diameters of 21 and 24 mm, respectively. ZnS nanoparticles at pH valuesof 5 and 7 promoted the efficiency of C, NA, and CN antibiotics and they had agood impact against S. typhi and B. cereus bacteria.
