[Characteristics of spore formation in Clostridium botulinum type C]. 1978

A A Shakhbanov

Electron microscope study of C1. botulinum, tyep C, showed that microbial cells were surrounded with a five-layer wall. Structures characteristic of sporulating cells and phage particles whose intracellular development led to reduction and lysis of the cytoplasm were revelaed in the area of the cytoplasm. Mature spores were encountered rarely. Formation of prespore, cortex was observed, but the elements of the spore membrane were chaotically dispersed in the whole cytoplasm. Such disturbances could be connected with the presence of phage in the culture.

UI	MeSH Term	Description	Entries
D008854	Microscopy, Electron	Microscopy using an electron beam, instead of light, to visualize the sample, thereby allowing much greater magnification. The interactions of ELECTRONS with specimens are used to provide information about the fine structure of that specimen. In TRANSMISSION ELECTRON MICROSCOPY the reactions of the electrons that are transmitted through the specimen are imaged. In SCANNING ELECTRON MICROSCOPY an electron beam falls at a non-normal angle on the specimen and the image is derived from the reactions occurring above the plane of the specimen.	Electron Microscopy
D003014	Clostridium botulinum	A species of anaerobic, gram-positive, rod-shaped bacteria in the family Clostridiaceae that produces proteins with characteristic neurotoxicity. It is the etiologic agent of BOTULISM in humans, wild fowl, HORSES; and CATTLE. Seven subtypes (sometimes called antigenic types, or strains) exist, each producing a different botulinum toxin (BOTULINUM TOXINS). The organism and its spores are widely distributed in nature.
D013171	Spores, Bacterial	Heat and stain resistant, metabolically inactive bodies formed within the vegetative cells of bacteria of the genera Bacillus and Clostridium.	Bacterial Spores,Bacterial Spore,Spore, Bacterial
