Answer #1

Answer:- The presence of glutamic acid in the peptide moieties of the bacteria makes the cell wall almost invulnerable to protease designed to cleave between glutamic acid. They also provide fitness against low osmolarity and stationary phase stresses such as starvation, growth arrest or accumulation of secondary metabolites.

    Part A Which of the following statements accurately describes bacterial cell walls? In bacteria with acid-tast cell walls, the carboxylic acid in the walls forms a layer outside a thin layer of hydrophilic polypeptides. The cell walls of gram-negative bacteria contain many more layers of peptidoglycan than those of gram-positive bacteria. In gram-negative bacteria, the thin layer of peptidoglycan is surrounded by an outer membrane made of phospholipids, lipopolysaccharides, and proteins Gram-negative bacterial cell walls contain teichoic acids, whereas the...

    50 years ago, people thought we were approaching the end of what had been the war against infectious diseases that had occurred since the dawn of humanity. However, recent evidence has shown that not only are we constantly in danger of “new” diseases, but are still facing issues with traditional diseases that have increased resistance to available drugs. Answer the following questions. 1, What is the difference between Emerging and Re-emerging Infectious Diseases? 2. What is a broad-spectrum drug? 3....
