Stenotrophomonas maltophilia are opportunistic, multi-drug-resistant Gram-negative pathogens increasingly prevalent in clinical settings. Quorum sensing (QS) systems play a crucial role in their pathogenesis, coordinating bacterial populations and enabling interactions within polymicrobial communities. While not the primary QS mechanism in S.

In swine, H3N2 subtype is associated with human-to-swine spillovers of seasonal viruses. In Latin America, the molecular and antigenic characteristics of swine FLUAV H3N2, as well as its phylogenetic origin, are poorly understood.

This study aimed to determine the frequency of hereditary cancer syndromes (HCS) in Colombians with solid tumors and to characterize the spectrum of PVs. Using data from the Colombia's largest Institutional Hereditary Cancer Program, we included patients aged ≥18 years with solid tumors who met HCS criteria and were offered genetic testing with a 105-cancer gene panel.

However, no vaccines or therapies are currently available. In this study, a recombinant Sendai virus (SeV) vector encoding the SRLV gag-P25 gene (rSeV-GFP-P25) from the EV1 strain was generated using In-FUSION cloning and rescued using the SeV reverse genetic system.
