Although this occurs rarely, such an infection nearly always results in the death of the victim.2 The case fatality rate is greater than 95%.3 NAgler, an early 20th century Austrian bacteriologist first identified amoebae that pass through a
biflagellate stage.
Dunaliella is a unicellular, naked
biflagellate green algae, and without cellular membrane.
Perkinsus marinus has a nonphotosynthetic plastid in the
biflagellate zoospore stage (Perkins 1996).The presence of a plastid in Perkinsus spp.
Thus, in SEM preparations, sperms with
biflagellate tail were observed (fig.7c).
Many algae, such as Ulva, in addition to
biflagellate gametes, exhibit flagellated zoospores (quadriflagellate in the case of Ulva) produced by the sporophyte.
Eggs are fertilized by motile,
biflagellate sperm during, or shortly following, the release of eggs from the oogonia.
