Hypothesis
This study aimed to comprehensively analyze virulence factors, antibiotic resistance patterns, and biofilm formation in clinical isolates of K. pneumoniae.
Conclusion
K. pneumoniae demonstrates notable biofilm-associated antibiotic resistance, supported by a significant association with XDR strains.
Supporting Evidence
- 88.15% of the analyzed isolates were identified as K. pneumoniae.
- High resistance rates were observed for cefepime (88.55%) and imipenem (85.82%).
- 4.22% of isolates formed strong biofilms, while 25.87% formed moderate biofilms.
Takeaway
K. pneumoniae can stick to surfaces and form a protective layer, making it hard to treat with antibiotics, especially in hospitals.
Methodology
The study collected 402 K. pneumoniae isolates from clinical samples, performed antimicrobial susceptibility testing, assessed biofilm formation, and conducted MLST analysis.
Potential Biases
Potential bias in sample collection and testing methods could affect the generalizability of the findings.
Limitations
The study was limited to isolates from Hamadan hospitals, which may not represent broader geographical trends.
Participant Demographics
The isolates were predominantly from tracheal samples, with a gender distribution of 53.73% women and 46.26% men.
