The control of infectious diseases caused by bacterial pathogens has been a challenge in recent years, due to the spread of bacterial resistance to various antibiotics. 1Increased antibiotic resistance in Gram-negative bacteria has raised serious public health concern. 2 Acinetobacter is a Gram-negative, non-motile coccobacillus classified in the family Moraxacellaceae. 3,4These microorganisms can be resistant to multiple drugs. 3Being ubiquitous in nature, these bacteria are part of the normal flora of the oropharynx, human skin, and perineum in approximately 20 to 25% of healthy individuals. 3In addition, they can develop in hospital settings, largely due to their persistence on abiotic surfaces, 5 becoming an opportunistic pathogen causing life-threatening infections such as pneumonia, bacteraemia and meningitis in hospitalised 1-
