Machine Learning Predicts Antibiotic Resistance in Pseudomonas, But MIC Breakpoints Are Still Tricky!
By combining genomic and transcriptomic data with machine learning, researchers achieved high accuracy in predicting antibiotic resistance in Pseudomonas aeruginosa for several antibiotics. Gene expression data significantly improved prediction, especially for ceftazidime, meropenem, and tobramycin, and classifiers performed better when MIC values were further from breakpoints.
Possible Conflicts of Interest
None identified.
Identified Weaknesses
Phylogenetic bias
The study acknowledges potential biases due to the phylogenetic structure of the bacterial population, which might lead to the identification of markers distinguishing between phylo-groups rather than purely resistance/susceptibility.
Limited generalizability
The study uses a specific set of clinical isolates, and the generalizability of the findings to other clinical settings or different P. aeruginosa populations needs further validation.
MIC testing variability
The accuracy of MIC testing, used as the gold standard, has inherent variability, especially near breakpoint values, which affects the performance of classifiers in those regions.
Rating Explanation
This is a strong study with a robust methodology using a large dataset of clinical isolates and combining genomic and transcriptomic data for improved prediction accuracy. The integration of machine learning techniques and the focus on a clinically relevant problem add to its value. However, the limitations regarding phylogenetic bias, generalizability, and MIC testing variability prevent a top rating.
