Right ventrolateral view of oral infraciliature

Description:

Right ventrolateral view (optical section) of the oral infraciliature of Dexiotrichides centralis (STOKES, 1886). The blue, green and light blue arrowheads indicate the kinetosomes of the first (M1), second (M2) and third (M3) adoral membranelles respectively. The pink arrowhead indicates the undulating membrane on the right margin of the cytostome. The yellow arrowhead indicates the rhomboidal scutica, unciliated kinetosomes of the buccal anlage. Densley stained endosymbiotic bacteria are seen in the cytoplasm (white arrowhead). Stained by the silver carbonate technique (Foissner,W. Europ. J. Protistol.27:313-330;1991).Brightfield.
