[NDM-1 cases and outbreaks in Turkey].

Area of Science:

• Microbiology
• Infectious Diseases
• Antimicrobial Resistance

Background:

• The study addresses a commentary regarding the identification of carbapenem-resistant strains, specifically New Delhi Metallo-beta-lactamase (NDM-1) producers.
• It clarifies the methods used for isolate selection, highlighting the limitations of ertapenem sensitivity and the Modified Hodge Test (MHT).

Discussion:

• The authors explain their choice of molecular methods over MHT for enhanced sensitivity in detecting NDM-1 producing isolates.
• They discuss previously reported NDM-1 cases in Turkey, noting publication timelines and potential clonal relationships or foreign origins.

Key Insights:

• Molecular methods are preferred over MHT for accurate NDM-1 detection due to higher sensitivity and specificity.
• NDM-1 producing isolates may have origins linked to foreign sources before becoming endemic.
• The study emphasizes the importance of ertapenem's sensitivity but notes its specificity limitations for NDM-1 identification.

Outlook:

• Healthcare facilities, especially those treating foreign patients, must implement robust NDM-1 identification protocols.
• Effective control measures are crucial to prevent the further spread of NDM-1 producing bacteria.
• Continued surveillance and molecular characterization are essential for understanding NDM-1 epidemiology.
