Background: Porcine reproductive and respiratory syndrome virus (PRRSV) is a major threat to swine industry worldwide, especially virulent variants arising during the last years, such as Spanish PRRSV-1 Rosalia strain. The role of the nasal microbiota in respiratory viral infections is still to be unveiled but may be promisingly related with the health status of the animals and thus, their susceptibility. The goal of this project was to study the nasal microbiota composition of piglets during a highly virulent PRRSV-1 outbreak comparing animals that died due to the infection with animals that survived it.

Background: The zoonotic and highly infectious pathogen Francisella tularensis is the etiological agent of tularemia. Tularemia in humans is mainly caused by F. tularensis subspecies tularensis and holarctica, but Francisella species like F.

Pseudomonas aeruginosa is a Gram-negative bacterium that is notorious for airway infections in cystic fibrosis (CF) subjects. Bacterial quorum sensing (QS) coordinates virulence factor expression and biofilm formation at population level. Better understanding of QS in the bacterium-host interaction is required.

Non-O1/non-O139 (NOVC) strains inhabit aquatic environments and sporadically induce human illnesses. This study involved the virulence and antimicrobial genetic characterization of 176 NOVC strains, comprising 25 from clinical samples and 151 from environmental sources, collected between 2021 and 2023. The antimicrobial susceptibility of the examined NOVC population was predominantly high, exhibiting only poor susceptibility to colistin, with 89.
