Summary

Tadução automática

Hier beschrijven we de constructie van nulmutanten van Aeromonas in specifieke glycosyltransferasen of regio's die glycosyltransferasen bevatten, de beweeglijkheidstests en flagellenzuivering die worden uitgevoerd om de betrokkenheid en functie van hun gecodeerde enzymen in de biosynthese van een glycaan vast te stellen, evenals de rol van deze glycaan in bacteriële pathogenese.
