Abstract:
Klebsiella pneumoniae is responsible for a wide range of infections, including urinary tract infections, pneumonia, bacteremia, and liver abscesses. In addition to susceptible clinical isolates involved in nosocomial infections, multidrug-resistant (MDR) and hypervirulent (hvKP) strains have evolved separately in distinct clonal groups. The rapid geographic spread of these isolates is of particular concern. However, we still know little about the virulence of K. pneumoniae except for hvKP, whose secrets are beginning to be revealed. The treatment of K. pneumoniae infections is threatened by the emergence of antimicrobial resistance. The dissemination of resistance is associated with genetic mobile elements, such as plasmids that may also carry virulence determinants. A proficient pathogen should be virulent, resistant to antibiotics, and epidemic. However, the interplay between resistance and virulence is poorly understood. Here, we review current knowledge on the topic.
Insights
Klebsiella pneumoniae infections are a growing concern due to multidrug-resistant and hypervirulent strains. This review explores the complex relationship between antimicrobial resistance and pathogen virulence in K. pneumoniae.
Area of Science:
- Microbiology
- Infectious Diseases
- Antimicrobial Resistance
Background:
- Klebsiella pneumoniae causes diverse infections like pneumonia and UTIs.
- Multidrug-resistant (MDR) and hypervirulent (hvKP) strains are emerging and spreading globally.
- Understanding K. pneumoniae virulence is limited, especially regarding the interplay with resistance.
Purpose of the Study:
- To review current knowledge on K. pneumoniae virulence.
- To examine the relationship between antimicrobial resistance and virulence in K. pneumoniae.
- To highlight the challenges in treating K. pneumoniae infections.
Main Methods:
- Literature review of scientific articles on K. pneumoniae.
- Analysis of studies on virulence factors and resistance mechanisms.
- Synthesis of information on genetic mobile elements like plasmids.
Main Results:
- Hypervirulent K. pneumoniae (hvKP) strains are increasingly recognized.
- Antimicrobial resistance in K. pneumoniae is often linked to mobile genetic elements, such as plasmids.
- The interaction between resistance and virulence in K. pneumoniae remains poorly understood.
Conclusions:
- The emergence of MDR and hvKP strains poses a significant threat.
- Further research is needed to elucidate the interplay between resistance and virulence.
- Effective treatment strategies for K. pneumoniae infections require addressing both resistance and virulence.
