Homework Answers
The answer is BACTERIAL CAPSULES.
Explanation: It is bedcause all the strains of bacteria mentioned
here, i.e., STreptococcus pneumoniae, Haemophilus influenzae,
Streptococcus mutants,, all three of these has capsules as their
virulence fctors.

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 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 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 61 What are the main factors involved in dissemination of these bacteria from their initial site to other locations in the body? The ability of their capsules to form biofilms, adhere to host tissues, and resist phagocytic engulfment. The ability to enter epithelial cells with invasions in order to resist defense molecules and not have to compete for nutrients. Using adhesins and invasions at their tips, along with their rotating motility, to pass through or between endothelial cells of...

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 59 Why did the injection of capsular material from Hemophilus influenzae type b enable to remove this bacterium from the body? It enabled the body to make antibodies against the axial filaments thus blocking bacterial motility. It enabled the body to make antibodies against pili and cell wall adhesins thus blocking the bacterium from attaching to phagocytes. It enabled antibiotics used in treatment to better penetrate bacterial capsules It enabled the body to make opsonizing antibodies against the bacterial...
