Pathogen Detection Beta

NCBI Pathogen Detection integrates bacterial and fungal pathogen genomic sequences from numerous ongoing surveillance and research efforts whose sources include food, environmental sources such as water or production facilities, and patient samples. Foodborne, hospital-acquired, and other clinically infectious pathogens are included.

The system provides two major automated real-time analyses: 1) it quickly clusters related pathogen genome sequences to identify potential transmission chains, helping public health scientists investigate disease outbreaks, and 2) as part of the National Database of Antibiotic Resistant Organisms (NDARO), NCBI screens genomic sequences using AMRFinderPlus to identify the antimicrobial resistance, stress response, and virulence genes found in bacterial genomic sequences, which enables scientists to track the spread of resistance genes and to understand the relationships among antimicrobial resistance, stress response, and virulence.

The new AST Browser displays submitter supplied antibiotic susceptibility testing data (AST) in a tabular format.
