Putative Bronchopulmonary Flagellated
Protozoa in Immunosuppressed Patients.
After settlement, the larval flagellated cells dedifferentiate into a simple cell mass on the substratum; thereafter they differentiate again into the three principal cell types of a juvenile sponge.
The coeloblastula is a hollow spheroid consisting of a layer of flagellated cells around a large central cavity (Fig.
Figures 4 and 5 show magnified images of the apical region of flagellated cells.
The larvae are covered by a layer of flagellated epithelial cells, which disappear within 24 h, at about the time of larval settlement, to a substrate such as rocks, shells, etc.
The present study addresses the fate of peripheral flagellated cells in Microciona larvae with methods other than those used in previous reports.
Peripheral flagellated cells showed an intense brown stain with the con A probe for mannose [ILLUSTRATION FOR FIGURES 1A,B OMITTED], but only a weak stain with GlcNAc [ILLUSTRATION FOR FIGURE 1C OMITTED], and no stain at all with the other lectins tested (SBA, DBA, PNA, UEA-1) (not shown).
While alive, she slept on a pile of bricks, wore gloves filled with nettles, flagellated
herself with chains, and gouged her flesh with shards of glass.
In minutes, the cysts turn into what Burkholder calls "toxic flagellated
vegetative cells" and propel themselves towards the fish.
The larvae use a surface layer of flagellated cells to swim around for a while, then settle on a substratum.
In calcareous sponges, larval flagellated cells are transformed into the choanocytes of a juvenile during metamorphosis (Duboscq and Tuzet, 1937; Amano and Hori, 1992, 1993).
Bd is called a chytrid fungus from the Greek chytridium, meaning "little pot" because small blisters filled with sperm-like, flagellated
zoospores form in the skin of infected frogs.
