Question

do inclusion bodies cause senescence, or does their formation indicate a correlation and what mchanism is repsonible for aging in bacteria?

Answer 1

Answer) Ageing or Senescence in bacteria can be described under two categories as: (a) Senescence in asymetrically dividing bacteria- Under this category, bacteria such as swimmers and motile comes,here the progeny produced by individual cells decrease its activity with age (b) Senescence in symetrically dividing cells-Under this category bacteria such as E. coli, in this case old cells shows decline in growth rate results in localization of inclusion bodies near the cell wall,this further reduces the diffusion of materials across cell wall and thereby the activity of bacterial metabolism reduces and leads to senescence and ultimately death.
