Characterization of Hypervirulent Klebsiella pneumoniae (Hv-Kp): Correlation of Virulence with Antimicrobial Susceptibility

Table 2

Differentiation of Klebsiella pneumoniae isolates into classical (C-Kp) and hypervirulent (Hv-Kp) type based on phenotypic and genotypic markers.

Isolated from	Total	Virulence marker		K. pneumoniae type (%)
		Hyper-mucoviscous	Aerobactin gene	C-Kp	Hv-Kp
Blood (central line)	35	05	04	31 (88.6)	04 (11.4)
Biopsy (deep tissue, etc.)	07	0	0	07 (100.0)	0
BAL	03	0	0	03 (100.0)	0
Exudate (pus/Drain/Abscess/Swab)	18	05	05	13 (72.2)	05 (27.7)
ET suction tip	13	04	02	11 (84.6)	02 (15.4)
Fluids (CSF/Pleural)	04	01	01	03 (75.0)	01 (25.0)
Sputum	04	01	01	03 (75.0)	01 (25.0)
Urine	45	07	05	40 (88.8)	05 (11.1)
Total	129	23	18	111 (86.1)	18 (13.9)

% isolates in each type of infection; classification as Hv-Kp was based on possession of Aerobactin gene.
