  • This study explores how non-ionic surfactants, specifically Cremophor EL and Cremophor RH40, can help inhibit efflux pumps in multidrug-resistant (MDR) bacteria, which often render antibiotics ineffective.
  • Researchers confirmed the presence of MDR strains and tested how these surfactants, combined with ciprofloxacin, affected minimum inhibitory concentrations (MIC).
  • Results showed that both surfactants significantly reduced MIC values of ciprofloxacin, indicating their potential to enhance the effectiveness of existing antibiotics against resistant strains.

Estimating dispersion in populations that are extremely rare, hidden, geographically clustered, and hard to access is a well-known challenge. Conventional sampling approaches tend to overestimate the variance, even though it should be genuinely reduced. In this environment, adaptive cluster sampling is considered to be the most efficient sampling technique as it provides generally a lower variance than the other conventional probability sampling designs for the assessment of rare and geographically gathered population parameters like mean, total, variance, etc.
