Objective: Multidrug-resistant bacteria, including carbapenem-resistant Acinetobacter baumannii (CRAB), are considered a major public health threat, particularly those which are responsible for nosocomial infections. This study aimed to investigate the molecular mechanism of carbapenem resistance and the clonal relationship of CRAB isolates of a probable outbreak in the intensive care unit (ICU) of Saydet Zgharta University Medical Center, in north Lebanon.

Methods: Thirty-two non-duplicate CRAB isolates were collected from patients hospitalised in the ICU.

Carbapenem and colistin-resistant bacteria represent a global public health problem. Refugees carrying these bacteria and living in inadequate shelters can spread these microorganisms. The aim of this study was to investigate the intestinal carriage of these bacteria in Syrian refugees in Lebanon.

Introduction: The increasing incidence of infections caused by multidrug-resistant bacteria is considered a global health problem. This study aimed to investigate this resistance in Gram-negative bacteria isolated from patients hospitalized in North-Lebanon.

Methodology: All isolates were identified using the matrix-assisted laser desorption/ionization time-of-flight mass spectrometry.

: Bacterial infections resulting from wars and natural disasters represent a major public health problem. Over the past 50 years, Asia and the Middle East have suffered several wars. Moreover, East-Asian countries are considered the most natural disaster-prone countries in the world.

Objectives: The increase in resistance to antibiotics has led to the revival of colistin as the last option for treatment, which automatically led to an increase of colistin-resistant, Gram-negative bacteria. In this study, we report the presence of clinical colistin-resistant Enterobacteriaceae isolated from a Lebanese hospital.

Methods: From 23 rectal swabs, eight colistin-resistant clinical strains (five Escherichia coli, two Enterobacter cloacae, and one Klebsiella pneumoniae) were isolated.

This study aims to describe the molecular mechanisms of carbapenem and colistin resistance in strains isolated from hospitalized patients in Lebanon. We report in this study the first description of producing carbapenem-resistant ST383, as well as the presence of two out of five isolates resistant to colistin due to mutations in the amino acid sequences of proteins (, , and ). Therefore, screening of such isolates may be effective in limiting the spread of these resistant microorganisms in hospitalized patients and within the community.
