The and genes, which code for UDP-ManNAc-dehydrogenase and UDP-GlcNAc-2-epimerase, respectively, are involved in capsular polysaccharide biosynthesis in A1. loss to the cattle industry (50). Several A1 virulence factors Tpo have been characterized; these include leukotoxin (3, 21, 27, 46), neuraminidase (45), lipopolysaccharide (LPS) (49), and transferrin binding proteins (35, 36). A1 cells are also encapsulated.… Continue reading The and genes, which code for UDP-ManNAc-dehydrogenase and UDP-GlcNAc-2-epimerase, respectively, are
