| Objective: Klebsiella pneumoniae, one of the clinical superbugs, causes diverse infections
because of its variable capsular antigens. This study focused on K. pneumoniae and aimed to
assess any correlation between capsular serotype, capsule-associated virulence genes, and
evaluate its resistance to conventional antibiotics in order to gain insight into any regional
differences.
Materials and Methods: A total of 61 K. pneumoniae collected from various clinical
specimens were confirmed genotypically. Clinical and demographic data for all patients were
reviewed. All isolates were subjected to antimicrobial susceptibility tests. Capsular serotyping
and capsule-associated virulence genes were studied using the molecular method.
Results: All typeable isolates were typed into K5, K20, and K54 serotypes, and among
them, K54 was observed to be predominant. The most common capsule-associated virulence
genes comprised uge (93.4%), ycfM (91.8%), and wabG (88.5%), while wcaG (29.5%) and
rmpA (21.3%) were noted at much lower prevalence rates. The gene wcaG was significantly
associated with K54 positive isolates (p = 0.001), while rmpA was associated with K20
positive isolates (p = 0.01).
Conclusion: Serotype K54 had a high frequency in isolates collected from patients with
pulmonary diseases, while serotype K20 was associated with burn patients. Carbapenems
and levofloxacin were the best therapeutic options for the treatment of infections with
serotypes K20 and K54. |
