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...

آب حاصل از بارش منبع تأمین نیازهای بی شمار جانداران به ویژه انسان است و هرگونه کاهش در کم و کیف آن مستقیماً حیات موجودات زنده را تحت تأثیر منفی قرار می دهد. نوسان سال به سال بارش از ویژگی های اساسی و بسیار مهم بارش های سالانه ایران محسوب می شود که آثار زیان بار آن در تمام عرصه های اقتصادی، اجتماعی و حتی سیاسی- امنیتی به نحوی منعکس می شود. چون میزان آب ناشی از بارش یکی از مولفه های اصلی برنامه ...
15 صفحه اولA Biochemical Study of Proteus Vulgaris
In this study we deal with the cultural properties, the products of growth, the pathogenicity, and the toxicity, of two strains of Proteus vulgaris, Hauser. This is an exceedingly interesting organism on account of its wide distribution, the ease with which it is modified, and because it seems to stand between the true saprophytic and the purely pathogenic bacteria. It has been found under a gr...
