Hypothesis

Can spirulina algal extract effectively combat carbapenem-resistant Klebsiella pneumoniae?

Conclusion

The study found that spirulina algal extract has promising antibacterial and antibiofilm activities against carbapenem-resistant Klebsiella pneumoniae.

Supporting Evidence

  • Spirulina extract showed minimum inhibitory concentrations ranging from 500 to 1000 µg/mL against K. pneumoniae.
  • Histopathological analysis indicated improvement in lung architecture in treated mice.
  • Spirulina extract inhibited biofilm formation in 68.75% of the tested isolates.

Takeaway

Spirulina, a type of green algae, can help fight off bad bacteria that don't respond to regular medicines.

Methodology

The study involved in vitro and in vivo testing of spirulina extract against K. pneumoniae, including antibiotic susceptibility testing and histopathological analysis.

Participant Demographics

30 clinical isolates from various samples including blood, urine, and sputum.
