Table 2 Comparison of biofilm-forming ability between carbapenemase-producing (CP-Kp) and nonproducing Klebsiella pneumoniae (CN-Kp) isolates (Fisher’s exact test)
Biofilm formation | CP-Kp, n = 52 (%) | CN-Kp, n = 37 (%) | Total, n = 89 (%) | p value |
|---|---|---|---|---|
No biofilm | 9 (17.31) | 17 (45.95) | 26 (29.21) | 0.0046 |
Weak | 18 (34.62) | 14 (37.84) | 32 (35.96) | 0.8243 |
Moderate | 22 (42.31) | 4 (10.81) | 26 (29.21) | 0.0018 |
Strong | 3 (5.77) | 2 (5.41) | 5 (5.62) | 1.0000 |
