Bacterial flagella and axial filaments
These are used for locomotion and adhesion on mucous membranes.
These are having glycoproteins which acts as virulent factor for various bacteria.
Axial filaments allow the spirichetes to penetrate mucous membrane and skin and enter blood vessels.
QUESTION 20 These structures enable some bacteria to move through mucous and contact mucosal epithelial cells...
QUESTION 22 These cell wall proteins allow many bacteria to adhere tightly to host cells, colonize, and resist flushing. This is used as a virulence factor by Bordetella pertussis, Helicobacter pylori, and Streptococcus pneumoniae, and Neisseria gonorrhoeae. This best describes what? Bacterial flagella and axial filaments. Bacterial cell surface proteins called adhesins. Bacterial capsules (glycocalyces). Bacterial invasions Bacterial pili.
QUESTION 19 These structures are usually composed of a polysaccharide slime that enables some bacteria to resist phagocytic engulfment and adhere to host cells, often as biofilms. They are used as a virulence factor by Streptococcus pneumoniae, Haemophilus influenzae, and Streptococcus mutans. This best describes what? Bacterial flagella and axial filaments, Bacterial cell surface proteins called adhesins. Bacterial capsules (glycocalyces), Bacterial invasions. Bacterial pili.
QUESTION 21 These proteins, often injected into host cells by a type 3 secretion system, allow certain bacteria to penetrate cells by inducing phagocytosis of the bacteria by the host cell. As a result, these bacteria don't have to compete for nutrients and can resist many body defense molecules. This is used as a virulence factor by Shigella, Yersinia, and Salmonella. This best describes what? Bacterial flagella and axial filaments. Bacterial cell surface proteins called adhesins. Bacterial capsules (glycocalyces). Bacterial...
QUESTION 18 These structures are protein tubules with adhesive tips that the bacterium can change. The adhesive tips are able to adhere to receptors on host cells, enabling the bacterium to colonize and resist flushing. They are used as a virulence factor by such bacteria as Neisseria gonorrhoeae and Neisseria meningitides, and Pseudomonas aeruginosa. This best describes what? Bacterial flagella and axial filaments. Bacteria cell surface proteins called adhesins, Bacteria capsules (glycocalyces) Bacteria invasions Bacteria pili
