RESUMO
Technologies to study localized host-pathogen interactions are urgently needed. Here, we present a spatial transcriptomics approach to simultaneously capture host and pathogen transcriptome-wide spatial gene expression information from human formalin-fixed paraffin-embedded (FFPE) tissue sections at a near single-cell resolution. We demonstrate this methodology in lung samples from COVID-19 patients and validate our spatial detection of SARS-CoV-2 against RNAScope and in situ sequencing. Host-pathogen colocalization analysis identified putative modulators of SARS-CoV-2 infection in human lung cells. Our approach provides new insights into host response to pathogen infection through the simultaneous, unbiased detection of two transcriptomes in FFPE samples.

Burkholderia cenocepacia is able to cause infections in cystic fibrosis patients. B. cenocepacia phage Paku has a 42,727-bp genome sharing a phiKMV-like genome arrangement. T7-like tail components were identified in parallel with a tyrosine integrase, suggesting that Paku might exhibit a temperate lifestyle, an atypical feature for an Autographiviridae phage.
