title: Intracytoplasmic flagellum in trypanosomatids.
abstract: Electron microscopy of thin sections and detergent extracted preparations of certain trypanosomatids of the genus Phytomonas revealed the unusual presence in some flagellates of an intracytoplasmic flagellum which appears as a naked axoneme encircling the nucleus before emerging at the anterior end of the cell. Another feature of these atypical flagellates is the absence of the flagellar pocket normally present in trypanosomatids at the emergence of the flagellum.
