Schizogony is a form of asexual reproduction seen in certain parasitic protozoa, particularly in the phylum Apicomplexa. It is also known as multiple fission or merogony. In schizogony, a single cell undergoes multiple rounds of nuclear division without any subsequent cytoplasmic division.

During schizogony, a parent cell replicates its genetic material (DNA) multiple times by undergoing multiple rounds of nuclear divisions (mitosis). This leads to the formation of multiple nuclei within the parent cell. However, the cytoplasm of the cell remains undivided, resulting in a multinucleated parent cell. This process allows for the production of numerous daughter cells within a single parent cell.

Once the nuclear divisions are completed, the parent cell undergoes a process known as cytokinesis, which involves the separation of the cytoplasmic contents into individual daughter cells. These daughter cells are genetically identical to each other and to the parent cell.

In parasitic protozoa, schizogony plays a crucial role in the life cycle of the organism. The daughter cells, also called merozoites, are typically infectious and capable of invading host cells. In the case of malaria-causing protozoa, such as Plasmodium, the merozoites are released from the infected red blood cells and can invade new red blood cells to continue the infection cycle.

Schizogony is a significant mechanism for rapid multiplication and expansion of the parasite within the host’s body. It allows the pathogen to establish and maintain a high parasite load, leading to increased pathogenicity and potential harm to the host.

In summary, schizogony is a form of asexual reproduction seen in parasitic protozoa, involving multiple rounds of nuclear division without cytoplasmic division. It facilitates the rapid multiplication of the parasite within the host’s body, aiding in their survival and spread.
