SPI1
toxin to bacteria into the host and toxify cell.
All components of the type 3 secretion system
SPI14
Encod T1SS in the invasion of polarized cells by Salmonella
channel to the plasma membrane and use ATP
purpose to get Sii1 to attach to the host and infect the disease
Binds to epithelial cells
SPI1 vs SPI4
?
each repsresnt diffferent infections in the cells

Figure 1
How many bacteria are in the host
without type 3 secretion SPi1 cannot get into the hot cells
SPI4 and SPI5
?
SPI4
important for invading apical polarized cells
SPI5 in blood stream
In polarized cells SPI5 is important in infection of cells. Enters macrophage to enter the bone marrow and get into other organs.
SiiC role in entering host cells
SiiF, b, c and e all of the genes are impotatant for cells infection for salmonella. if SiiC is removed than no enter into host cells.
