Streblomastix
A symbiotic eukaryote that lives in the hindgut of termites, Streblomastix is a protist associated with a community of ectosymbiotic bacteria.
Streblomastix strix moves by beating its anterior flagella. When cells move forward, they usually rotate counterclockwise, during which time the flagella point backward; while during the reverse movement, the flagella point forward.
Streblomastix strix is able to move directionally toward sodium acetate (its presumed food source) (chemotaxis). Studies have shown that the bacteria covering its surface act as sensory symbionts, receiving environmental signals and transmitting them to the host to guide its movement.
These protists measure around 100 micrometers in length. The axostyle in Streblomastix strix exhibits a significant evolutionary divergence from the motile, contractile axostyles typical of many oxymonads. They completely lack mitochondria and Golgi apparatus.They have Club-shaped body
with a naked anterior end, which is used to attached to the gut surface of termites.The surface of the cell features longitudinal ridges separated by deep furrows. Unlike the axostyle inside the cell, these extended ridges structures are completely lacking in microtubule support.The organism possesses four flagella, which are used for locomotion.
In cross-section, the cell's has a stellate, or star-shaped, form with ectosymbiotic bacteria surround them. Except for the anterior region, the surface of Steblomastix strix is almost entirely covered with long, rod-shaped epibiotic bacteria. These bacteria are arranged end-to-end along the longitudinal lamina.The bacteria do not attach randomly, but are anchored via specialized "biconcave knots" on the host cell membrane. These knots precisely accommodate the ends of adjacent bacteria, forming stable connections.
These epiphytic bacteria may act as the host's extracellular skeleton. When antibiotics are used to remove the bacteria, Streblomastix strix loses its star-shaped and elongated form, transforming into a teardrop-shaped structure, indicating that its morphology is highly dependent on the support of the symbiotic bacteria.
Streblomastix strix is found only in the hindgut of dampwood termites, particularly in the genus Zootermopsis of the family Termopsidae.
