Triadic Dynamics of Gastric Bacterial Microbiome, Phageome, and Host Genotype, with Implications for Disease Associations

Aleksander Szymczak, Katarzyna Gembara, Joanna Majewska, Paulina Miernikiewicz, Stanisław Ferenc, Jan Janusz Gnus, Marlena Kłak, Natalia Jędruchniewicz, Wojciech Witkiewicz, Krystyna Dąbrowska

The paper investigates the triadic interactions between gastric bacterial microbiome, phageome, and host genotype, finding that phages are influenced by both bacterial hosts and human genetic variants.
