The Fine Structure of Chondrococcus Columnaris
An electron microscope study of the myxobacterium Chondrococcus columnaris has revealed the following structures in the peripheral layers of the cells: (1) a plasma membrane, (2) a single dense layer (probably the mucopeptide component of the cell wall), (3) peripheral fibrils, (4) an outer membrane, and (5) a material coating the surfaces of the cells which could be stained with the dye ruthen...

Kingsbury, David T. (University of Washington, Seattle), and Erling J. Ordal. Bacteriophage infecting the myxobacterium Chondrococcus columnaris. J. Bacteriol. 91:1327-1332. 1966.-During a series of screening experiments, seven bacteriophages which infect the pathogenic myxobacterium Chondrococcus columnaris were isolated. Of these, one was chosen for detailed study. This phage has a wide host ...
متن کاملStudy of a bacteriophage infecting the myxobacterium Chondrococcus columnaris.
Lysed areas suggestive of phage activity were observed on a plate in the course of isolation of a strain of Chondrococcus columnaris from trout at the Fisheries Center of the University of Washington. C. columnaris is an aquatic fruiting myxobacterium responsible for epizootics in salmonid and other fishes (Ordal and Rucker, 1944). Subsequently a bacteriophage was isolated which infected and ly...

In 1922 Davis described an infectious disease which was responsible for heavy mortalities in a number of species of warm water fishes in the Mississippi Valley. Although Davis was unsuccessful in his attempts to cultivate the etiological agent, he reported that large numbers of slender, motile bacteria were characteristically present in the lesions of infected fish. He further noted that when m...

هدف از انجام این تخقیق بررسی رابطه احتمالی بین سطح مهارت زبان خارجی (foreign language proficiency) و ساختار مهارت زبان خارجی بود. تعداد 314 زبان آموز مونث و مذکر که عمدتا دانشجویان رشته های زبان انگلیسی در سطوح کارشناسی و کارشناسی ارشد بودند در این تحقیق شرکت کردند. از لحاظ سطح مهارت زبان خارجی شرکت کنندگان بسیار با هم متفاوت بودند، (75 نفر سطح پیشرفته، 113 نفر سطح متوسط، 126 سطح مقدماتی). کلا ...
