- How Liquefactive necrosis can generate disease ? please Explain at your own wordsGive the genus and species of two Gram-positive pathogenic bacteria that are hemolytic , and give the diseases they cause in humans .Streptococcus pyogenes, the main causative agent of bacterial pharyngitis (aka “Strep throat”) is differentiated from other Streptococcus species by type of hemolysis; S. pyogenes is ______ hemolytic on a Blood Agar Plate (BAP).
- What is the principle of the coagulase test result? How does coagulase contribute to the virulence of some bacterial species?Using this flow chart, a species that is alpha-hemolytic and catalase-negative is Streptococcus pyogenes Streptococcus pneumoniae Enterococcus faecalisCoagulase is aknown factor in the ability of S. aureus to cause infection. However, coagulases-negative staphylococci may be pathogenic as well. What are some of the factors that contribute to virulence of coagulase-negative bacteria?
- Show a diagram of beta-hemolysis and alpha-hemolysis by different bacteria on blood agar and explain with detail.The general public takes for granted the link between an infectious agent and a given infection Discuss the requirements established by Koch, the nineteenth-century German scientist, before ascertaining, for instance, that Helicobacter pylori bacterium is the cause of the gastric ulcer. Why is it so essential to meet these conditions?One of the symptoms of patients with severe Corona virus infection is acidosis. Explain why this may be fatal to the individual.
