WebMost bacteria of this genus have a constant ratio of cell length and their diameter is 2: 1. Their surface is smooth and has no cilia. Certain species of this genus, grown on liquid media, demonstrate the capacity of developing involution forms and of linking the cells into greater complexes which may appear in a form of flocculus. WebINVOLUTION FORMS AND PLEOMORPHISM: Certain species of bacteria are known to exhibit variation in shape and size of individual cells. This variation is known as pleomorphism. Swollen and aberrant forms may be seen in ageing cultures of Nesseria gonorrhoeae and Yersinia pestis or in the presence of high salt concentration.
