Isolation of an oral filamentous microorganism.
In the past, a wide variety of unrelated oral filamentous and rod shaped bacteria were placed either in the genera Leptothrix or Leptotrichia. The confusion resulted from meager studies of many of these organisms, inadequate generic descriptions, and use of the ill-defined word "filamentous." Bergey's Manual of Determinative Bacteriology in 1948 stated, "the genus Leptotrichia Trevisan, 1879 is...
متن کاملUltrastructure of an anaerobic filamentous oral micro-organism.
Thin sections of an anaerobic filamentous oral organism possibly related to Leptotrichia buccalis have been examined in the electron microscope. The organism exhibited a cell wall profile characteristic of Gram-negative bacteria, viz. a solid membrane and an outer double-layered membrane. The outer membrane could be removed by treating intact cells with trypsin or phenolwater. The organism cont...
متن کاملMicroorganism and filamentous fungi drive evolution of plant synapses
In the course of plant evolution, there is an obvious trend toward an increased complexity of plant bodies, as well as an increased sophistication of plant behavior and communication. Phenotypic plasticity of plants is based on the polar auxin transport machinery that is directly linked with plant sensory systems impinging on plant behavior and adaptive responses. Similar to the emergence and e...
متن کاملCell wall analysis of oral filamentous bacteria.
The cell wall compositions of 41 strains of oral filamentous bacteria belonging to the genera Fusobacterium, Leptotrichia and Bacterionema were examined by paper chromatography. Leptotrichia walls showed principally alanine, glutamic acid, DAP, glycine and aspartic acid. The genus Bacterionema had the same amino acids but aspartic acid appeared to be a minor component and was not detected in th...
متن کاملCharacterization of strain HY99, a novel microorganism capable of aerobic and anaerobic degradation of aniline.
We have characterized a novel microorganism, strain HY99, which is capable of aerobic and anaerobic degradation of aniline. Strain HY99 was found to aerobically metabolize aniline via catechol and 2-hydroxymuconic semialdehyde intermediates, and to transform aniline via p-aminobenzoate in anaerobic environments. Physiological and biochemical tests revealed that strain HY99 was most similar to D...
