The process in which N. Meningitidis reproduces
is binary fission.
Binary fission is one of the most common ways for
bacterial cells to reproduce.
The steps of binary fission are as follows:
- Chromosome attaches to plasma
membrane
- Chromosome replicates
- Cell grows and protein ring
forms
- Protein ring in middle
constricts and the membranes and cell wall come in
and pinch together
- Fission is complete and two
genetically identical daughter cells are created
The product is two genetically
identical daughter cells.
This allows the bacteria to continue to replicate
without genetic abnormalities or changes that would
affect its growth or ability to be parasitic in humans.
Nutrition
N. Meningitidis is heterotrophic meaning it
survives off the organism in which it lives.
Since it also causes disease because of its
location in humans it is called a heterotrophic
parasite. The
bacteria gets its nutrients from the mucous membrane in
which it lives and also from the blood of humans in the
cases where it invades the circulatory system.
