ABSTRACT

 

Comparison of the antimicrobial activity of eucalyptus (Eucalyptus citriodora), clove (Syzygium aromaticum) and pine oils (Pinus sylvestris) against eleven Multiple Drug Resistant (MDR) pathogens was studied. Maximum antibacterial activity was shown by clove oil (Syzygium aromaticum), followed by eucalyptus oil (Eucalyptus citriodora). Pseudomonas aeruginosa was found to be inhibited maximum by clove oil. Eucalyptus and clove oils were found to be most effective against MDR pathogens, except Salmonella typhi. A comparative study of effect of fourteen essential oils on different species of same genera was performed and it was observed that the most pathogenic and most common species (Klebsiella pneumonia and Proteus vulgaris) were inhibited the least by the oils. Rare and less pathogenic species are found to be more sensitive towards the essential oils. Citrobacter diversus and Citrobacter freundii had shown almost similar sensitivity patterns.
