Acinetobacter baumanii, also known as ‘Iraqibacter’ ranked among the top most pathogens causing

hospital acquired infections. Acinetobacter baumanii is resistant to most of the antibiotics which is

attributed to its ability to form biofilms. The hike in antimicrobial resistance poses and extra ordinary

threat to human life and therefore developing new antimicrobial drugs become a compelling situation for

scientific community. Plants are the rich sources of bioactive compounds. Mankind depended on plants

to cure infections ever since life began. Essential oils secreted by the plants have been used since ancient

times in many traditional therapies. Essential oils are volatile odoriferous oil extracted from deferent plant

parts. In this study, the essential oil from inflorescence of Etlingera elatior (Torch ginger) is used to study

its antibacterial and antibiofilm effects on Acinetobacter baumanii. Essential oil was extracted from the

inflorescence using the Clevenger apparatus and stored at 40C. The oil was found to be a promising

antibacterial and antibiofilm agent against the selected bacteria. The components of essential oil were

identified using GC-MS analysis. Further studies are required to develop drug molecule from the selected

plant essential oil.
