T2 lipopolysaccharide antigen of Salmonella: comparison of the properties of T2 and mucoid forms.

摘要

The T2 form of Salmonella was found to resemble mucoid mutants to some extent by growing as rather slimy colonies, especially at low temperatures. Its sensitivity to rough-specific phages was greatly reduced at low temperature. However, the T2 form did not produce colanic acid. The mucoid mutants of Salmonella studies corresponded to previously described mucoid mutants of Escherichia coli culturally, chemically,and genetically.
