Blood group substances as
The level of cellular differentiation of human oral, sulcular, and junctional epithelium was compared by immunohistochemical analysis of cell membrane-associated blood group-specific carbohydrates. Identification of the blood group A-specific carbohydrate and its two immediate precursor substances, type 2 chain H and N-acetyllactosamine. was accomplished by an indirect immunofluorescence techni...
متن کاملCommen salism in pathogenic anaerobic Actinomyces cultures.
Conversion of a ‘rough’ typical strain of Actinomyces israelii of human origin to a ‘smooth’ soft form more tolerant of oxygen was found to result from the physical trapping within the mycelium of a few alien and facultatively anaerobic cells. Such cells, which commonly proved to be staphylococci, were isolated in single cell culture by micromanipulative techniques and then grown aerobically. T...
متن کاملAN AEROBIC SOIL MICROORGANISM WHICH DECOMPOSES BLOOD GROUP SUBSTANCES II. : Effect of Cell-Free Extracts on Blood Group Substances.
Cell-free extracts of a number of microorganisms have been shown to possess enzymatic activity against blood group substances. Thus, enzymes of Bacillus fulminans, isolated by Iseki and Tsunoda (1952), were found to attack O(H) but not A or B substances. Extracts from strains of Lactobacillus bifidus, var. penn, have been shown (Springer et al., 1954; Gyorgy et al., 1954) to break down A, B, an...
متن کاملMetabolic and serologic differentiation of Actinomyces bovis and anaerobic diphtheroids.
It is frequently a difficult task to differentiate Actinomyces bovis from "anaerobic diphtheroids" of questionable pathogenicity. Diphtheroids, isolated from normal and pathological tissues, resemble A. bovis morphologically and in some cultural characteristics. These similarities and lack of suitable criteria for their definitive identification have been responsible for the errors in separatin...
متن کاملSTUDIES ON BLOOD GROUPS Ill . PROPERTIES OF PURIFIED BLOOD GROUP A SUBSTANCES FROM INDIVIDUAL
Some of the properties of blood group A specific substances from enzymatic digests of pools of hog stomachs have been presented in the preceding report (1). However, since it was known that not all hog stomachs show A activity (2), it was considered of interest to determine whether better products could be isolated from individual hog stomachs. When stomach linings from a number of individual h...
