Genomic tool untangles how microbes spread—even when they look almost identical

Phys · · 819 words · By Wellcome Trust Sanger Institute
Public Health Improvement Advancement in Genomic Technology

Researchers have developed a new genomic tool called TRACS to track the spread of microbes with high precision. This tool analyzes small genetic differences (SNPs) to determine if pathogens were transmitted directly or acquired from a shared source. The technology was tested on data from SARS-CoV-2, Streptococcus pneumoniae, and Plasmodium falciparum, showing its potential for improving infection prevention and developing new treatments.

“In a collaboration between experts at the Peter MacCallum Cancer Center in Australia, the Wellcome Sanger Institute and the University of Oslo, researchers used the TRACS tool to map the transmission of the SARS-CoV-2 virus, the bacterium that causes pneumonia, Streptococcus pneumoniae, and the malaria parasite, Plasmodium falciparum, across different populations.”
CORROBORATED
At least one web search result explicitly mentions the collaboration between experts at the Peter MacCallum Cancer Center, the Wellcome Sanger Institute, and the University of Oslo, and the use of TRACS to map the transmission of SARS-CoV-2. The claim lists three pathogens (SARS-CoV-2, S. pneumoniae, and P. falciparum), and the evidence confirms the involvement of the institutions and the mapping of SARS-CoV-2, while also referencing the other pathogens in the context of the overall research area.

“To address this, an international team developed TRACS, a highly accurate and easy-to-use algorithm that can distinguish between two closely related samples and tell whether they are likely to have come from a direct point of transmission or were acquired at the same source.”
SINGLE SOURCE
The provided web search results for this claim relate to a commercial product named 'TRACS Direct' (ordering/inventory management) and do not corroborate the scientific description of TRACS as an algorithm distinguishing transmission types. Therefore, the claim cannot be corroborated by independent sources, but the web search results are not contradictory, leading to 'single_source' based on the limited, non-scientific evidence found.
