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).
The lambda phage, also called Enterobacteria phage Î» and colphage Î», is a type of temperate bacteriophage or bacterial virus that infects the Escherichia coli (E. coli) species of bacteria. The virus may be housed in the genome of its host via lysogeny.n order to infect a host cell, the bacteriophage attaches itself to the bacteriaâs cell wall, specifically on a receptor found on the bacteriaâs surface. Once it becomes tightly bound to the cell, the bacterial virus injects its genetic material (its nucleic acid) into the host cell.
