Question
Chapter 28.3, Problem 1TQ
Summary Introduction
To review:
The process to determine the source of nosocomial infection with MRSA in the provided case.
Introduction:
Methicillin-resistant of Staphylococcus aureus (MRSA) is a bacterium which belongs to Gram-positive bacteria and is responsible for causing a number of infections in the body. Treatment for this strain is tougher when compared to other strains of Staphylococcus aureus because they are resistant to antibiotics that are commonly used. The symptoms of MRSA change depending on the part it infects.

Assume you work at the local hospital in your home town. Suddenly you notice that 10% of your patients are having serious staphylococcal infections. None of these patients were admitted for having a staphylococcal infection, and we assume that all standard infectious control procedures are being followed (hand washing, use of gloves and masks, etc.). Remember that a small percentage of bacteria do evade even the most scrupulous of infectious disease control procedures. How could you use what you have learned in this week’s laboratory to solve the problem?
How could you find out where the infection originated? What steps would you need to take?
How could you determine definitively what organism is causing these patients’ infections?
How could you determine how to treat these patients?
Once you determine the source of the infection, what ethical issues, if any, are involved here? What should you do to protect the privacy and welfare of the patients as well as avoiding conduct…
In 2013, there was an outbreak of methicillin-resistant Staphylococcusaureus (MRSA) at an NFL training facility. One player suffereda career-ending infection to his foot and sued the team owners for $20 million for unsanitary conditions that contributed to the bacterialinfection. A settlement with undisclosed terms was reached in2017. MRSA is highly contagious and is spread by direct skin contactor by airborne transmission and can result in amputation or death.In addition, MRSA is very difficult to treat because it is resistant tomany antibiotics. For example, b -lactam antibiotics, such as penicillin,function by binding to and inactivating bacterial penicillin-bindingproteins (PBPs), which synthesize the bacterial cell wall. However,MRSA expresses an alternative type of PBP, called PBP2a encodedby the mecA gene. b -lactam antibiotics only weakly bind PBP2a,and thus cell wall synthesis can continue in their presence. Moreover,in a system somewhat analogous to the regulation of the…

- Identifying an unknown bacterium is an essential step in the diagnosis and treatment process. Since not every antibiotic is effective against every type of bacteria, knowing what caused a particular infection allows us to make correct prescriptions so patients can recover more quickly. Knowing the cause of an infection also prevents antibiotic resistance as well, since incorrect prescriptions allow bacteria to be unnecessarily be exposed to antibiotics, increasing the chances of developing resistance.arrow_forwardIn 2013, there was an outbreak of methicillin-resistant Staphylococcusaureus (MRSA) at an NFL training facility.

M. tuberculosis is transmitted indirectly via air droplets that are inhaled in the large and small airways. In fact, although 30% of individuals exposed to the bacteria will develop an infection, only 5-10% will develop clinical manifestations. This means 20-25% of people exposed to the bacteria will have a latent disease. Although people with latent disease are not infectious and will not transmit the disease to other community members, latent disease is difficult to diagnose. This was really playing on Lilly's mind, thinking about the difficulty of controlling the spread of the bacteria when most infected people were asymptomatic for years and then suddenly developed active disease, which could then spread for weeks…arrow_forward
- Imagine a newly developed drug that is highly lethal against all stages in the life cycle of Toxoplasma gondii. The drug has been found to be safe and effective both for human and for veterinary use. Although the drug can eliminate infection in both humans and cats, its use in humans will have vey little impact on overall prevalence of human toxoplasmosis. Its use in cats, alternatively, could, at least in theory, reduce prevalence in both humans and cats. Explain this difference.arrow_forwardUsing the Koch's Postulates, support the findings that Mycobacterium tuberculosis is the causative agent of tuberculosis. Specifically, you have to provide brief narratives/pictures/proofs and sources that support the postulate listed below: The organism must be isolated from the newly infected animals and cultured again in the laboratory, after which it should be seen to be the same as the original organism.arrow_forwardA 65-year-old woman has a long-term central venous catheter for intravenous therapy. She develops fever and subsequently has multiple blood cultures positive for Staphylococcus epidermidis. All of the S. epidermidis isolates have the same colony morphology and antimicrobial susceptibility pattern, suggesting that they are the same strain. In what possible way do you think she has contracted the bacteria? Which link in the chain of infection has broken in this particular scenario and what will be your advice to avoid such infections?arrow_forward
- Select all of the following that applies to the tradeoff between transmission and virulence that applies to many diseases. a) The tradeoff between transmission and virulence means that diseases always evolve to become more virulent. b) If greater virulence limits transmission, that disease will likely evolve to become less virulent than it could be. c) While making more copies of itself can increase the likelihood of transmission occurring, too much replication of the disease can make the host so sick it won't leave the house and spread the disease. d) A strain of a disease that replicates enough to be transmitted, but not so much that the host gets too sick to move, will be favored by natural selection over strains that either make the host too sick or do not replicate enough to be transmitted. e) If a disease can spread without making its host sick (e.g. when the host is asymptomatic), then the tradeoff between transmission and virulence…arrow_forwardIn 1971, Alfred Knudson noticed that children like Kay, who have retinoblastoma in both eyes (bilateral), presented at earlier ages than those who had unilateral disease. To explain these different disease kinetics, he proposed the “two-hit hypothesis.” What does this hypothesis propose?arrow_forwardAnthrax is O 1) a zoonosis. O2) only seen sporadically in the United States. O 3) a disease that, in humans, can cause a rapidly fatal toxemia and septicemia. 4) transmitted by contact, inhalation, and ingestion. O 5) All of these choices are correct.arrow_forward
- Different strains of Streptococcus pyogenes have different virulence factors, giving these microbes much versatility. Virulence factors include which of the following? Choose one or more: A.A capsule that, when thick, will help the organism avoid phagocytosis by macrophages B.A cell wall containing lipoteichoic acid, thought to facilitate adherence to pharyngeal epithelial cells C.Enzymes that lyse blood cells (streptolysins) D.The production of several endotoxins called streptococcal pyogenic endotoxins (SPEs)arrow_forwardA group of researchers wanted to evaluate the effectiveness of mask-wearing, handwashing, social distancing, and other personal protective measures in preventing COVID-19 infections They recruited two groups of participants. Those in group 1 tested positive for COVID-19, whereas those in group 2 tested negative for COVID-19. Each of the participants in each group had a history of recent contact with someone who was confirmed COVID-19 positive . Thereafter, participants in each group were asked whether they wore a face mask, the type of mask, and the frequency of wearing a mask; whether and how frequently they practiced handwashing; and whether they complied with social distancing guidelines. The above describes which of the following epidemiological study designs ? a. Cohort study b. Descriptive study c. Cross-sectional study d. Case-control studyarrow_forwardThe intestinal epithelium produces a variety of antimicrobial peptides that play a crucial role in establishing the balance of commensal organisms versus pathogens constituting the healthy host microbiota. Studies have found that, in Crohn's disease, individuals have dysbiosis, a condition in which there is disruption of the normal composition of the host microbiota. It is, therefore, not surprising that several cases of Crohn's disease have been linked to: Reduced recruitment of neutrophils to the intestinal mucosa O Increased IL-10 secretion by intestinal macrophages O Reduced production of IL-1-3 in response to microbial antigens O Defects in production of antimicrobial peptides in Paneth cells O Reduced number of Th17 cells in the lamina propriaarrow_forward
