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 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
QUESTION 20 These structures enable some bacteria to move through mucous and contact mucosal epithelial cells in order to colonize. They also enable spirochetes to penetrate mucous membranes, skin abrasions, and cell membranes, enter blood vessels and disseminate to other locations in the body. This is used as a virulence factor by Helicobacter pylori, Treponema pallidum and Borrelia bergdorferi. This best describes what? Bacterial flagella and axial filaments. Bacterial cell surface proteins called invasins. Bacterial capsules (glycocalyces). Bacterial cilia and...
QUESTION 39 Which best describes a type 3 secretion system? A system that allows bacteria to transfer virulence factors from one bacterium to another by horizontal gene transfer. A system that enables bacteria to directly injecting bacterial effector molecules into the cytoplasm of the host cell in order to alter its cellular machinery or cellular communication. A system that allows bacteria to sense their own population density by communicating with each other by way of secreted chemical factors and behaving...
