- Pathogens have a variety of traits that interact with a host and enable the pathogen to enter a host, adhere to host cells, gain access to nutrients, and escape detection or removal by the immune system. These traits are called virulence factors. The following enzymes and toxin can act as virulence factors and contribute to bacteria’s pathogenicity. What are the specific actions of the following enzymes and toxin that make them virulence factors? Coagulase Kinase (such as staphylokinases and streptokinases) Hyaluronidase Collagenase CytotoxinPlease answer the one question below, thanks In 2013, there was an outbreak of methicillin-resistant Staphylococcus aureus (MRSA) at an NFL training facility. One player suffered a career-ending infection to his foot and sued the team owners for $20 million for unsanitary conditions that contributed to the bacterial infection. A settlement with undisclosed terms was reached in 2017. MRSA is highly contagious and is spread by direct skin contact or by airborne transmission and can result in amputation or death. In addition, MRSA is very difficult to treat because it is resistant to many antibiotics. For example, β-lactamβ-lactam antibiotics, such as penicillin, function by binding to and inactivating bacterial penicillin-binding proteins (PBPs), which synthesize the bacterial cell wall. However, MRSA expresses an alternative type of PBP, called PBP2a encoded by the mecA gene. β-lactamβ-lactam antibiotics only weakly bind PBP2a, and thus cell wall synthesis can continue in their…Antibiotic resistance is a real threat to the human race. Unfortunately, it has not been given the kind of attention it deserves. So a lot of people are unaware of the seriousness of the situation and its consequences. You are expected to do a literature search about this burning issue and turn in a paper. I am not particular about the style you use for the paper. But I am particular about the fact that you must reference every statement you make if you are taking it from somewhere. I want you to use the ACS format to cite your reference Your paper must have an introduction. Your paper must read like an essay (headings are optional). If you use a question answer format I will not grade your paper. Please do not use the numbering or bullet format in writing the paper, the use of paragraphs is more appropriate. Please ensure that your paper is cohesive in font and writing style. In your paper please address the following issues · What are antibiotics? · What is antibiotic resistance? ·…
- Provide evidence in supporting or refuting the following statement: The cell, or cytoplasmic membrane, is a nonessential structure in bacteria because its function is replaced by the cell wall in these microbes. please provide minimum of 400 of words. Thank you!In terms of microbial pathogenicity, molecular Koch's postulates are a set of experimental criteria that show: A microbe is the aetiological agent of a disease A gene encodes a product that contributes to disease A gene encodes a product that contributes to immunity to a disease A mutation does not contribute to diseaseMost hospitals use hand sanitizers that claim to “kill 99.99% of illness causing germs”. What are some possible reasons that 0.01% of germs (germs = microorganisms and viruses) not affected by hand sanitizer? (In your answer, you should state what hand sanitizer is made of, and the mechanism by which it kills “germs”.
- I am having a hard time digesting this article https://www.sciencedaily.com/releases/2016/04/160429095038.htm to answer the following questions Summarize the article in 4-6 bullet points. How does this article relate to the information you've read/watched in Module 2? Discuss in detail /reflect on info from textbook, articles, videos about our immune system and our gut microbes. Does your chosen autoimmunity article involve the innate immune system or the adaptive immune system? or both?- Explain.Provide evidence in supporting or refuting the following statement: The cell, or cytoplasmic membrane, is a nonessential structure in bacteria because its function is replaced by the cell wall in these microbes. provide at least 400 of wordsSome antibiotics fail to kill/inhibit a pathogen simply because the microbe is naturally (intrinsically) resistant to it. True or False ?
- can you explain why Bacillus anthracis can be pathogenic in a mouse and not be fought off by the immune system? I need help finding the answer in the article and explain in short answer link to article: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC106848/write a brief summary on the KPC bacteria, What clinical significance does this organism have for humans? (What disease/infections does it cause in humans?) What is the mode of transmission to humans? (How do you get an infection with this organism?) What is the worldwide geographic distribution for this organism? (Where is it found, have there been any reported cases or outbreaks lately?)Most antibacterial drugs disrupt or destroy prokaryotic cellular structures or processes that are different than those of eukaryotic cells or may not even be present in eukaryotic cells. List and describe at least three prokaryotic cellular features that could be targeted to inhibit or kill a bacterial pathogen without harming its eukaryotic host.
