A bacillus (plural bacilli) is a rod-shaped bacterium. Bacilli are found in many different taxonomic groups of bacteria. However, the name ''Bacillus'', capitalized and italicized, refers to a specific genus of bacteria. The name Bacilli, capitalized but not italicized, can also refer to a less specific taxonomic group of bacteria that includes two orders, one of which contains the genus ''Bacillus''. When the word is formatted with a lowercase and not italicized, 'bacillus', it will most likely be referring to shape and not to the genus at all. The shape bacillus can also be called rods. 〔(【引用サイトリンク】title=The Size, Shape, And Arrangement Of Bacterial Cells )〕 Bacilli usually divide in the same plane and are solitary, but can combine to form diplobacilli, streptobacilli, and palisades.〔(CHAPTER 4 FUNCTIONAL ANATOMY OF PROKARYOTIC AND EUKARYOTIC CELLS ).〕 *Diplobacilli: Two bacilli arranged side by side with each other. *Streptobacilli: Bacilli arranged in chains. *Coccobacillus: Oval and similar to coccus (circular shaped bacterium). 〔(【引用サイトリンク】title=Sizes, Shapes, and Arrangements of Bacteria )〕 There is no connection between the shape of a bacterium and its color in the Gram staining. MacConkey agar can be used to distinguish among Gram negative bacilli such as ''E. coli'' and salmonella. ==Examples of Gram positive bacilli== * ''Clostridium'' genus * ''Corynebacterium'' genus * ''Listeria'' genus * ''Propionibacterium'' genus 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Bacillus (shape)」の詳細全文を読む スポンサード リンク
