Textbook Question
Chapter 11.4, Problem 1EG
Consumer products including bandages, cotton balls, diapers, and contact lens solutions are routinely irradiated. There is no opposition to these products in the marketplace. Given this, why are irradiated foods not more accepted when they can prevent illness from E. coli and other pathogens?

- there are different methods to be used in order to control opportunistic infection and that includes cleaning, sanitizing, disinfecting, sterilizing... And that depends how they can be applied according to the area and level the health care worker or scientist is and the environment. Do you know how these methods of microbial growth are applied and where?arrow_forward7) A patient who has been on her Amoxicillin regimin for 5 days calls your doctor's office today and says that she is experiencing a black "hairy" tongue and full body rash that is not raised or itching. Which of the following, after consultation with the physician, would be your BEST response to her? A) You are experiencing a medical emergency and you need to hang up and call 911. B) These are an idiosyncratic reaction to the medication. Go to the emergency department immediately. C) You're going to die! D) These are normal side effects of treatment with Penicillins. Call back or call 911 if you have difficulty breathing.arrow_forwardNonhealing wounds on the surface of the body are often extremely difficult to manage, in part because the microbial cause of the lack of healing is often extremely difficult to identify. Create a list of 4 reasons this might be the case.arrow_forward
- If a patient suspected to have sepsis or meningitis, samples for bacterial testing should be taken before giving antibiotics. Explain why?arrow_forwardAs you can see on the blood agar plates, some microbes can lyse red blood cells releasing nutrients into the surrounding area. What might the advantage be for a bacteria to be able to do this? Do you think this could have an effect on the bacteria’s virulence? Explain.arrow_forwardDifferent 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_forward
- Which of the following types of antimicrobial drugs make microbes more susceptible to osmotic pressure? 1) drugs that inhibit nucleic acid synthesis O 2) drugs that inhibit metabolic pathways 3) drugs that inhibit cell wall synthesis 4) drugs that block a pathogen's recognition of its host 5) drugs that inhibit protein synthesisarrow_forward3) Make the match with the terms and definitions Bioinert Undergoes degradation in the body and can be secreted naturally Bioactive Causing "no" biological effect/host response Biodegradable Produces an unexpected effect on living tissue 4) Which one of the below given properties belongs to second generation biomaterials ? a) Minimal reaction/interaction with the body b) stimulate specific cell responses at molecular level c) controlled reaction with the physiological enviroment d) Biointeractive and resorbablearrow_forwardA 65 year old patient undergoes a hernia repair surgery. He receives a polypropylene mesh implant that prevents hernia recurrence. The healing goes well, but four weeks after the surgery he develops fever and sense of discomfort at the surgery site. On a physical examination, there is skin redness and fluctuating mass (palpable mass filled with fluid) around the incision. The doctor suspects that mesh got infected and plans mesh removal surgery. 1) Describe the sequence of local events during wound healing after the implantation of the mesh. For each of the stages of the wound healing process, specify cells that are involved, their role(s), signal molecules that are involved, and their roles. 2) Which pathogen most likely caused the infection? 3) After initiation of antibiotic treatment, the symptoms are resolved in two days and the patient stops taking antibiotic against the doctor's advise. Two weeks later, the mesh is removed and analyzed. It is found that a small area of the mesh…arrow_forward
- A patient in ICU with an indwelling medical device is presenting with invasive infection symptoms, specifically fever and chills. They have been on a course of antibiotics that has not alleviated the condition. a) What type of organism do you suspect is causing the infection and why?arrow_forwardThe type of antimicrobial drug that would be most likely to have toxic effects in humans based on the premise of selective toxicity when treating microbial infection would be a drug that O 1) inhibits the synthesis of the cell wall O 2) inhibits metabolic pathways O 3) disrupts the cytoplasmic membrane 4) inhibits protein synthesis 5) All of the above have equal potential to be toxicarrow_forwardWhich of the following is true of commensal bacterium? Question 2 options: A) commensal bacteria do not receive any benefit from its host B) commensal bacteria only colonize adult hosts C) commensal bacterium may also be an opportunistic pathogen D) commensal bacterium cannot cause an infection its hostarrow_forward
