Studies on Bacterial Localization
THE RESULTS OF GROSS AND MICROSCOPIC OBSERVATIONS AND SURVIVAL TESTS AFTER SUBCUTANEOUS INFECTION OF MICE WITH TYPE I PNEUMOCOCCI CAN BE SUMMARIZED AS FOLLOWS: Normal mice possessed no adequate means of protection against this organism. The bacteria disseminated freely through the tissue spaces in the presence of widespread inflammation, and were not ingested by significant numbers of host cell...
متن کاملStudies on Bacterial Nutrition
1. Certain anaerobic bacteria grow under aerobic conditions in plain broth in the presence of sterile unheated plant tissue. 2. Aerobic growth of anaerobic bacteria under the above conditions may be related to the presence of growth-accessory substances, and to the action of oxidizing-reducing systems of plant tissue in the destruction of toxic peroxides of bacterial origin.
متن کاملStudies on Bacterial Enzymes
The meningococcus cell contains a peptonase enzyme which hydrolyzes the peptides and similar constituents of commercial "peptone." The activity of this enzyme is independent of the presence of the formed bacterial cell. The peptonase enzyme is more resistant to heat and to oxidation than is the maltase enzyme of the same bacteria.
متن کاملChemical Studies on Bacterial Agglutination
1. A method, conforming to the criteria of quantitative analytical chemistry, is described for the estimation of the agglutinin content of antisera. Examples are given of the application of the method to various antipneumococcus sera. 2. This new, absolute method is discussed with regard to its relation to the commonly used relative methods.
متن کامل9i. Saccharase Activity in the Barley Plant
IT has long been recognized that most plant tissues have the capacity of inverting sucrose, but intensive study of saccharase action has hitherto been almost exclusively concerned with the saccharase of yeast [O'Sullivan & Tompson, 1890; Hudson, 1908, 1, 2; Michaeis & Menten, 1913; Nelson & Hitchcock, 1921; von Euler & Josephson, 1923; Willstatter & Kuhn, 1923; Weidenhagen, 1930, and many other...
