Alteraciones en el tracto urinario durante la infección con Proteus mirabilis que expresa la toxina codificada en plásmido (Pet)

Abstract: La toxina Pet (plasmid-encoded toxin) producida por Escherichia coli (EAEC) es uno de los autotransportadores más estudiados en la familia Enterobacteriaceae.Es responsable de cambios morfológicos enenterocitos durante la infección por EAEC. Recientemente, Pet fue encontrada en el genoma de una cepa de Proteus mirabilis RTX339 [P. mirabilis (Pet+)]. P. mirabilis causa infección en el tracto urinario (ITU) en pacientes que usan catéteres o que presentan anomalías estructurales o funcionales. En este estudio una… Show more

“…Considering all the data presented in this study and in other previously published works (Navarro-Garcıá et al, 1999;Navarro-Garcıá et al, 2001;Abe et al, 2008;Park et al, 2009;Nazemi et al, 2011;Herzog et al, 2014;Nunes et al, 2017;Espinosa-Antuńez et al, 2019;Carbonari et al, 2020;Freire et al, 2020;Mandomando et al, 2020;Schüroff et al, 2021;Nascimento et al, 2022), we suggest that Pet producer-EAEC could cause damage to the intestinal epithelium, translocate through the intestinal barrier and reach the bloodstream, degrading complement components and promoting bacterial immune evasion. Likewise, Pet-producing ExPEC could evade the complement system by direct cleavage of its components and successfully spreading throughout the host.…”

“…Pet binds and cleaves epithelial fodrin in vitro and in vivo, and this activity depends on the serine protease motif (Navarro-Garcıá et al, 1999;Villaseca et al, 2000;Navarro-Garcıá et al, 2001;Canizalez-Roman and Navarro-Garcıá, 2003;Navarro-Garcıá et al, 2007b;Nava-Acosta and Navarro-Garcia, 2013). Additionally, the Pet-encoding gene has been recently detected in E. coli strains isolated from extraintestinal sites (Abe et al, 2008;Tapader et al, 2014;Freire et al, 2020;Mandomando et al, 2020;Schüroff et al, 2021;Nascimento et al, 2022), and in Proteus mirabilis causing urinary tract infections (Espinosa-Antuńez et al, 2019).…”
