Cardiac outflow obstruction may also result in sudden-onset syncope with little or no prodrome. One critical clue is the exertional nature, and the other is the presence of a cardiac murmur. Young athletes may present with this etiology for syncope.
SUMMARY. Summary: Flagellar and translocation-associated type III secretion (T3S) systems are present in most Gram-negative plant-and animal-pathogenic bacteria and are often essential for bacterial motility or pathogenicity.o date, T3S4 proteins have been described for translocation-associated T3S systems from several animal-pathogenic bacteria (YscP from Yersinia spp., Spa32 from Shigella spp., and InvJ from Salmonella spp.) and the plant-pathogenic bacterium X. campestris pv. vesicatoria (HpaC) (Table 6).
Just as in humans, the plant microbiome is shaped by the types of bacteria that successfully colonize the plant's ecosystem. Most of these bacteria are symbiotic, drawing from and providing for the plant in ways such as nitrogen-fixing and leaf-protection. Pathogenic bacteria may also colonize a plant. Pathogens can include viruses and bacteria that damage the plant itself or bacteria like the Shiga-toxin producing E. coli O104:H4.
