 AB    The microsporidian parasite, Enterocytozoon bieneusi, is currently
       recognized as a potentially important cause of chronic diarrhoea in
       patients infected with the human immunodeficiency virus (HIV). Faecal
       concentrates from a 38-year-old, HIV-seropositive patient examined by
       light and electron microscopy revealed the presence of numerous
       microsporidian spores. The structural characteristics of the spores were
       consistent with those previously described for Enterocytozoon bieneusi.
       Each spore contained a single nucleus, a posterior vacuole and a polar
       filament with 6-7 overlapping coils which appeared in cross-section as a
       series of 3 doublets. Mature spores were surrounded by an inner unit
       membrane, an electron-lucent endospore and a thin, electron-dense
       exospore. The identity of the parasite was confirmed by the detection of
       unique endogenous developmental stages in duodenal biopsies. Both
       proliferative and sporogonial plasmodia (meronts and sporonts) were
       observed and all stages were monokaryotic (single nucleus) and
       apansporoblastic (sporophorous vesicle absent). Proliferative and
       sporogonial plasmodia divided by plasmotomy and spore organelles (polar
       filament, attachment disc and polaroplast) were well developed prior to
       fission of the sporogonial plasmodium.
