Arylamidase activity in cell extracts of sonically cell treated suspensions of 23 Salmonella strains, including 12 strains of S. typhimurium, was investigated. All cultures hydrolyzed five of nine different neutral and basic substrates. Activity against aspartyl-, cystyl- histidinyl-, and isoleucyl-beta-naphylamide was negligible. Alanyl-beta-naphthylamide was the preferred substrate for the Sa...
To extend the knowledge on the fragments of Proteus penneri lipopolysaccharide core regions, which determine the cross-reactions with specific antibodies, serological studies were performed by use of P. penneri 7 core-specific antiserum and Proteus sp. lipopolysaccharides. Different reactivity of the tested antiserum with three groups of antigens suggested differences in their core regions' epi...
The effect of temperature variation on the multiplication rates of two strains of Amoeba proteus and the corresponding heterotransfer strains obtained by transplantation of nuclei between the 'parent' strains, has been studied. The two 'parent' strains multiply at a similar rate at 17° C but at different rates at 27 C and 11° C. The multiplication rates of the heterotransfers follow the cytopla...

SYNOPSIS The properties and characteristics of 296 Proteus strains isolated from hospital patients and from sewage have been examined with a view to determining those characters which are of most use in following and detecting cross-infection. Ninety-six per cent of the organisms isolated were P. mirabilis and it was found that by identifying biotypes and by phage typing the species could be di...

BACKGROUND The Proteus syndrome is characterized by the overgrowth of skin, connective tissue, brain, and other tissues. It has been hypothesized that the syndrome is caused by somatic mosaicism for a mutation that is lethal in the nonmosaic state. METHODS We performed exome sequencing of DNA from biopsy samples obtained from patients with the Proteus syndrome and compared the resultant DNA s...
