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).
LOCALIZATION OF PEPTIDOGLYCAN SYNTHESIS. Rod-shaped bacteria are considered to have two modes of cell wall synthesis: one associated with elongation and one associated with formation of the division septum, which, after division, becomes the ânew poleâ of both daughter cells (Fig. 1).
