Bacillus. 2003. Bacterial flagella are a coiled, thread-like structure, sharp bent, consisting of a rotary motor at its base and are composed of the protein flagellin. 2.2: Prokaryotic cells lack internal membranes that compartmentalize their functions unlike Eukaryotic cells. 12.3b) pole. 1.2: Eukaryote Cell Difference between Prokaryotic and Eukaryotic Cells Works by ROTATION ... Sporulation: Endospore formation. Striated muscle. 7. Bacteria may possess a single polar flagellum (monotrichous), tufts of flagella at each pole (lophotrichous), one or more flagella at both poles (amphitrichous), or flagella surrounding the perimeter of the cell (peritrichous). Many prokaryotes are motile, and the majority of motile prokaryotes move by means of flagella. • Flagella are very simple in structure compared to flagella of other organisms. 12.3d). MCP. They are responsible for the bacterial motility. Bacterial Flagella. presentations for free. The thin structures of the bacterial flagella make it difficult to observe under bright field microscope. Our new CrystalGraphics Chart and Diagram Slides for PowerPoint is a collection of over 1000 impressively designed data-driven chart and editable diagram s guaranteed to impress any audience. Different types of structure of bacterial flagella, and how these structures contribute to pathogenicity. The Flagellum and Bacterial Motility. B. Fimbriae and pili. The presence of sterols in eucaryotic cells such as fungi is important in chemotherapy, since certain antifungal antibiotics react with sterols in membranes. 18 Axial filaments spirochetes similar function to flagella run lengthwise along cell snake-like movement.

MICROBIOLOGY MODULE Morphology and Classification of Bacteria Microbiology 2 Notes zMost bacteria possess peptidoglycan, a unique polymer that makes its synthesis a good target for antibiotics zProtein synthesis takes place in the cytosol with structurally different ribosome’s Fig. Flagellin is a subunit protein of the flagellum, a whip-like appendage that enables bacterial motility. Spiral. Only 23 of these proteins, however, are common to all the other bacterial flagella studied so far. They'll give your presentations a professional, memorable appearance - the kind of sophisticated look that today's audiences expect. In terms of speed and agility, flagella-powered bacteria would leave Olympic swimmers for dead. Bacteria may be motile by a variety of mechanisms (5), but the most common involves flagella.

The structure of bacterial flagella have been described by Simon (1978), Doestsch and Sjoblad (1980) and Ferris and Beveridge (1985).
