Coagulase 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?

Compare and contrast the virulence factors associated with Staphylococcus aureus and Streptococcus pyogenes. Which of these agents is the most difficult to treat. Explain your answer

Resistance to antimicrobial agents is more commonly seen in hospital-acquired infections with enteric bacteria than in community-based infections with the same species. Explain why this is so.

Explain why coagulase positive bacteria are more pathogenic than coagulase negative bacteria

Once these pathogens enter the host the difference in environmental conditions signals for them to germinate and turn into growing cells. Compare Inhalation anthrax (Bacillus anthracis) to Tetanus (Clostridium tetani). Besides endospores used in transmission, what is a simple explanation to help explain how each microbe survives and grows in each location?

Which of the following bacteria is the most common isolate from blood? Vibrio cholerae Mycobactererium tuberculosis Mycoplasmapneumoniae Helicobacter pylori Escherichia coli Which of the following bacteria often cause Otitis media (middle ear infections) in children? Mycoplasma pneumoniae Mycobactererium tuberculosis Streptococcuspneumoniae Helicobacter pylori Escherichia coli Which of the following influenza viruses is/are influenza B virus(es)? H1N1 H3N2 H7N9 All of the above None of the above

What is group B Streptococcus? What can be done to protect fetuses?

Why Leishmaniasis is called black fever?

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).

bacteria that are able to be killed by cephalexin are said to be: cephalexin resistant methicillin sensitive cephalexin sensitive selected for methicillin resistant
