Properties of Proteus mirabilis and Providence spheroplasts.
Proteus mirabilis strain I 3 and Providence strain NCTC 92 I I were converted to osmotically sensitive spheroplasts by growth in the presence of penicillin or glycine in sucrose-supplemented or unsupplemented medium. Lysazyme in the presence of tris and ethylenediaminetetra-acetic acid (EDTA) converted both these strains to spheroplasts. Penicillin spheroplasts could be stabilized with sucrose,...
متن کاملBiochemical investigation of Providence strains and their relationship to the Proteus group.
The search for the possible causative agents of acute infective diarrhoea in infants and children has brought to light a great number of groups and strains of enteric bacteria other than Salmonella and Shigella. None of them can yet be incriminated with certainty as being pathogenic. The problem of potential or conditioned pathogenicity cannot be solved without a more comprehensive knowledge of...
متن کاملAn improved ferric chloride test for differentiating Proteus-Providence group from other Enterobacteriaceae.
It has been found by a number of investigators that cell suspensions and sonic extracts of one species (Proteus vgaris) of the family Enterobacteriaceae contain an enzyme which catalyzes the oxidative deaTnination of most of the i,-amino acids to their corresponding a-keto acids (Bernheim et al., 1935; Uemura, 1942a, b; Uemura, 1944; Stumpf and Green, 1944). Henriksen (1950) utilized this facul...

چکیده: سرطان پستان دومین عامل مرگ مرتبط با سرطان در خانم ها است. از آنجا که سرطان پستان یک تومور وابسته به هورمون است، می تواند توسط وضعیت هورمون های استروئیدی شامل استروژن و پروژسترون تنظیم شود. استروژن نقش مهمی در توسعه و پیشرفت سرطان پستان ایفا می کند و تاثیر خود را روی بیان ژن های هدف از طریق گیرنده های استروژن اعمال می کند. اما گروه دیگری از گیرنده های هسته ای به نام گیرنده های مرتبط به ا...
