50
Salmonella typhi, paratyphi, enteritidis, and typhimurium are the ____
SEROTYPES/serovars
51
what does the kauffman white classification differentiate
isolates of a given serotype by determining the major antigens: important for tracking outbreaks to their source

58
shigella is oxidase ____
negative
59
shigella disease and reservoir is limited to ____
humans
60
how does shigella invade
cross mucosa via M cells, use invasins to enter epithelial cells,move thru host cell and spread to adjacent host cells via actin based motility
