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).
In this experiment, bacteria from the III-S strain were killed by heat, and their remains were added to II-R strain bacteria. While neither alone harmed the mice, the combination was able to kill its host.riffith was also able to isolate both live II-R and live III-S strains of pneumococcus from the blood of these dead mice. Griffith concluded that the type II-R had been transformed into the lethal III-S strain by a transforming principle that was somehow part of the dead III-S strain bacteria.
