(mī'krō-nēm),
A small, osmiophilic, cordlike twisted organelle found in the anterior region of many sporozoans; one of the characteristics that helps to define the subphylum Apicomplexa.

Full-length AMA1 is an 83-kDa polypeptide that is translocated to the apical organelle microneme at the time of invasion [13, 14], when the 83-kDa polypeptide undergoes N-terminal processing to form a 66-kDa form that is translocated to the merozoite surface 1,15].
Some sporozoites that are deficient in cell migration, such as spect (sporozoite microneme protein essential for cell traversal)-/- or spect2-/- sporozoites, are immobilized in the dermis, associated with CD11b+ cells, and destroyed by phagocytes [15].
