Frequency of CIT, EBC and DHA flocks (families) of AmpC beta-lactamases in clinical isolates of Klebsiella pneumoniae collected from hospitalized patients in North of Iran

Key Points

• Diverse families of AmpC beta-lactamases were identified among clinical isolates.
• The frequency of these beta-lactamases indicates a growing concern for antibiotic resistance.
• Analysis involved samples from hospitalized patients in Northern Iran over a defined period.
• Results highlight the need for ongoing monitoring of pathogenic resistance patterns.
