Correlation of minimal inhibitory concentrations (MIC) values of Benzalkonium chloride and chlorhexidine with resistance profiles (MDR, XDR, PDR) in Klebsiella pneumoniae isolates (N = 50)
| Resistance patterns | Benzalkonium chloride MIC (µg/mL) | chlorhexidine MIC (µg/mL) | p-values | ||||
|---|---|---|---|---|---|---|---|
| Mean | Median | Range | Mean | Median | Range | ||
| MDR(Multidrug resistance) | 23.00 | 16.00 | 8–64 | 59.67 | 64.00 | 8-128 | *P-value = 0.005 |
| XDR(Extensively drug resistance) | 43.60 | 16.00 | 8-256 | 63.00 | 64.00 | 4-128 | **P-value = 0.670 |
| PDR(Pan-drug resistance) | 85.33 | 64.00 | 32–256 | 48.00 | 40.00 | 8-128 |
P1 = 0.459 P2 = 0.001 P3 = 0.006 |
*p-value: Represents the statistical analysis of benzalkonium chloride MIC values in relation to resistance patterns
**P-value: Represents the statistical analysis of chlorhexidine MIC values in relation to resistance patterns
P1: Compares benzalkonium chloride MIC values between MDR and XDR strains
P2: Compares benzalkonium chloride MIC values between MDR and PDR strains
P3: Compares benzalkonium chloride MIC values between XDR and PDR strains
