Sporoplasm

Sporoplasm is an infectious material present in the cytoplasm of various fungi-like organisms, such as members of class Microsporidia. Sporoplasm is defined as a mass of protoplasm that gives rise to or forms a spore. The protoplasmic body that is released as an infective amoebula from a cnidosporidian cyst.

Mode of infection

It is injected to host cell through a coiled polar tube which acts as a spring-like tubular extrusion mechanism. It is mainly involved in the asexual cycle of the organism.

Reproduction

Inside the host cell, the sporoplasm multiplies to generate Apicomplexan [life cycle|meronts], cells with loosely organized organelles enclosed in a simple plasma membrane. Multiplication occurs either by merogony or schizogony or plasmotomy.
