	Blepharisma
		Blepharismas are protists that are commonly viewed under microscopes in science classes.
		Blepharisma is a microphagus filter feeder and a ciliate, it is classified in the phylum Ciliophora.
		Blepharismas generally eat bacteria from decomposing vegetation, which is drawn into the buccal cavity and then passes to the food vacuoles at the posterior end of the cell.

		As a primary compact macronucleus is already present, there is no condensation phase prior to the division and the macronucleus just elongates until it is divided between the two daughter cells, thus the binary fission process is analogue to that of most other ciliate species.
		The vegetative macronucleus (MA) is the present strain of Blepharisma consists of 4-9, generally 7, spherical nodes arranged as a bent string of beads with diameters from about 5 to 10 um.
		In Blepharisma's with a multinodal macronucleus a condensation of the latter takes place to form a spherical macronucleus, which reelongates before the cell splits to two daughter cells.

	BLEPHARISMA
		Blepharisma is a heterotrich ciliate and a microphagus filter feeder.
		But once the buccal cavity and all its associated structures are understood the organism as a whole is easier to view.
		Using what you know about the location of the buccal cavity and its related structures try to determine which view of the cell you are looking at.

	Blepharisma - Wikipedia, the free encyclopedia
		Blepharisma is a genus of heterotrich ciliates (a type of protista) which contains many species.
		Its members are elongated and roughly egg-shaped, with a contractile vacuole without collecting channels.
		Blepharisma reproduce by going through the 4 phases of Binary fission Blepharisma are covered in tiny hairlike parts called cilia.

	BioMedia organism identification contest
		Blepharisma is a ciliate protozoan that looks something like Paramecium (the genus of common ciliates named in many submissions to our contest).
		Blepharisma is covered with short cilia, except in the oral groove, where there are both longer membranelles (cilia bundles) and an undulating membrane running along a portion of the groove.
		If cultures of Blepharisma are left in the light for extended periods, the pink pigments fade away, whereas, the color of Blepharisma left in the dark is intensified.

	BioMed Central \| Full text \| A rapid and simple method of detection of Blepharisma japonicumusing PCR and ...
		Blepharisma japonicum is easily identified by a bright purple photopigment and is therefore a useful organism for developing and evaluating a molecular detection system.
		PCR amplification of DNA extracted from Blepharisma japonicum using primers BLEPTUBF and BLEPTUBR produced a band which co-migrated with the 400 bp marker and was therefore consistent with the predicted fragment size of 399 base pairs (Figure 1).
		To investigate the sensitivity of this process for the detection of Blepharisma, we carried out serial dilutions of DNA extracted from a known number of Blepharisma which were micromanipulated into an extraction tube and counted manually prior to extraction.

		Sustained treatment of Blepharisma cells with mastoparan also suppressed the photoresposiveness, as in the case of cell adaptation to light during prolonged illumination.
		Moreover, using antibodies raised against bovine transducin, a cross-reacting protein with an apparent molecular mass of about 55 kDa in the Blepharisma cortex fraction was detected on immunoblots.
		However, further experiments are necessary to clarify the possible coupling between the G-protein and the putative phospholipase C.

		This image shows the more normal, elongated body of the Blepharisma.
		Also visible is the dark undulatory membrane on the upper right - this is the feature that produces the waves that allow locomotion, much in the same manner as the Paramecium.
		In fact, under intense bright artificial light, the pink pigment will emit a poisonous toxin that causes the Blepharisma to completely disintegrate.

	FEBS Abstract
		Sobierajska K., Fabczak H., Groszy[nacute]ska B., Fabczak S. Blepharisma japonicum is a protozoan ciliate, which possesses a photoreceptor system that renders the cell capable of avoiding light (photophobic response).
		This photoreceptor system is coupled to photomotility changes via a G-protein-mediated sensory transduction pathway.
		The findings presented in this study suggest that the identified phosphoprotein in photosensitive Blepharisma may also participate in the regulation of sensory transduction resulting in photophobic response.
