Cristispira Cultivation

The cells of Cristispira are single, curved, helically curved or planar corrugated cells 0.5-3.0μm in diameter. The total length of the screw is more than 80 microns, and it can be as long as 150 microns, and there are 2-10 complete curls. The ends of the cells are either rounded, tapered, or pointed. Its cells reproduce by transverse division.

The cells of Cristispira may contain 30-80 consecutive rows of oval inclusions of unknown composition, which replace the nuclear structure and cause the cells to streak horizontally on the stained slides. Normal motion can be moved forward and backward by means of a non-rotating, moving helical wave. The helix can also rotate or flex along its long axis. There are more than 100 axial filament wrapped around the protoplasmic cylinder, which can be seen with phase contrast microscopy when clustered in bundles. Degradation is prone to occur when removed from or disturbed its habitat conditions. The axial filament can leave the protoplast within the coating of the expanded helix, forming so-called ridges. In addition, it can also develop into central and terminal macrovesicles and helical cysts. After the structure is formed, the movement becomes irregular and the cells can be lysed.

Cristispira is a symbiotic animal. It is widely distributed in the shells of two- and one-lobed mollusks in both marine and freshwater, and is usually found in crystalline tailpieces (a rod-like structure composed of mucus secretions) or in the fluids of the digestive tract. Also found in other animals, such as echinoderms and tunicates.

Cristispira Culture Service

Creative Biogene offers customizable Cristispira strain culture services. This service can help you obtain Cristispira cultures for subsequent scientific research. This service allows you to skip the complicated and tedious groping of culture conditions, which helps to speed up research on this strain.

Cristipira pectinis

Cristipira pectinis has cylindrical helical curved cells. The overall length of the helix is 36-72 microns, and the average width of the cells is 1.5 microns. Most Cristipira pectinis have four complete spirals. The ends are rounded or pointed, without apical appendages. There are 30-79 inclusion bodies in the cells, thus showing horizontal streaks and polar granules in the stained slides. Bend inwards before transversal splits. In fixed slices, ridges run along one side of the cell. Not easily seen on live specimens.

Cristipira pectinis are found in the stomach and intestines of scallops in the Gulf of Nabris (marine environment) and sometimes in their crystalline tail pieces.
