Carbapenem-resistant bacteria are a growing global threat. Researchers found the bla Oxa-72 gene, linked to resistance, in Acinetobacter calcoaceticus from Lebanese vegetables, suggesting a potential environmental reservoir.
Area of Science:
- Microbiology
- Environmental Science
- Public Health
Background:
- Increasing global reports of carbapenem-resistant Acinetobacter species pose a significant public health challenge.
- Carbapenem resistance in Acinetobacter spp. is a critical concern due to limited treatment options.
Purpose of the Study:
- To report the first detection of the bla Oxa-72 gene in Acinetobacter calcoaceticus from vegetables in Lebanon.
- To investigate the potential role of the Lebanese environment as a reservoir for antibiotic resistance genes.
Main Methods:
- Isolation and identification of Acinetobacter calcoaceticus from vegetable samples.
- Molecular detection of the bla Oxa-72 gene using appropriate genetic techniques.
Main Results:
- The bla Oxa-72 gene was successfully detected in an Acinetobacter calcoaceticus isolate.
- This marks the first identification of this specific carbapenemase gene in Acinetobacter spp. from vegetables in Lebanon.
Conclusions:
- The Lebanese environment, specifically vegetable sources, may act as a reservoir for the bla Oxa-72 antibiotic resistance gene.
- This finding highlights the need for surveillance of antibiotic resistance in environmental settings to understand transmission pathways.
