Abstract

The resistance of hospital bacterial isolates against traditional germicides, which used frequently, is one of the important factors contributing to emerging nosocomial infections. Moreover, due to having the side effects of chemical substances, the development of novel low-risk natural compounds seems necessary for control the spread of resistant pathogens in hospital environments. The aim of this study was to compare the effect of carvacrol and glutaraldehyde against two common hospital acquired pathogens, including Pseudomonas aeruginosa and Staphylococcus aureus. In this study 365 samples were collected from different wards of hospitals of Khorramabad, Iran. One hundred and sixty samples were identified as P. aeruginosa and S. aureus by using standard microbiological methods. Then the antibacterial effects of four combinations including carvacrol+ethanol, carvacrol+dimethyl sulfoxide (DMSO), glutaraldehyde 2%, and pure glutaraldehyde (50%) were evaluated and determined using dilution broth and disk diffusion methods. Our results showed that the carvacrol had more antibacterial effects against selected bacteria compared to glutaraldehyde. Moreover, the optimal time and concentration of carvacrol+ethanol against hospital isolates of P. aeruginosa and S. aureus was determined after 1 h at concentration of 64 μl/ml and 8 μl/ml, respectively. In conclusion by comparing the results of carvacrol and glutaraldehyde, seem that carvacrol, as an herbal and natural agent, may be a suitable alternative to glutaraldehyde in hospital equipment’s’ sterilization.
