BacteriologyTwo-Site Evaluation of the Colistin Broth Disk Elution Test To Determine Colistin In Vitro Activity against Gram-Negative BacilliLimited methods for colistin MIC determination are available to clinical microbiology laboratories. The purpose of this study was to evaluate the accuracy of the colistin broth disk elution (CBDE) test compared to that of broth microdilution (BMD) for identifying colistin MICs.
BacteriologyUsing Machine Learning To Predict Antimicrobial MICs and Associated Genomic Features for Nontyphoidal SalmonellaNontyphoidal Salmonella species are the leading bacterial cause of foodborne disease in the United States. Whole-genome sequences and paired antimicrobial susceptibility data are available for Salmonella strains because of surveillance efforts from public health agencies.

ParasitologyRole of Toxoplasma IgA as Part of a Reference Panel for the Diagnosis of Acute Toxoplasmosis during PregnancyThis study evaluated the usefulness of adding the Toxoplasma gondii IgA antibody enzyme-linked immunosorbent assay (ELISA) to the serologic panel of tests done for the diagnosis of acute toxoplasmosis in pregnant women in a reference laboratory in the United States. We conducted a retrospective study of 690 consecutive pregnant women with positive...
CommentaryPredicting Antimicrobial Resistance and Associated Genomic Features from Whole-Genome SequencingThanks to the genomics revolution, thousands of strain-specific whole-genome sequences are now accessible for a wide range of pathogenic bacteria. This availability enables big data informatics approaches to be used to study the spread and acquisition of antimicrobial resistance (AMR).
CommentaryThe Search for a Practical Method for Colistin Susceptibility Testing: Have We Found It by Going Back to the Future?Polymyxins are relied upon for the treatment of carbapenem-resistant Gram-negative bacterial infections, but polymyxin resistance is increasing. Only broth microdilution is recommended for polymyxin susceptibility testing, but this method is impractical for most clinical microbiology laboratories.
