To explain:
The steps which should be taken to restore normal microbiota of intestine after extended antibiotic therapy. Also, explain two ways by which exact microbiota and some representative species could also be returned.
Introduction:
Normal microbiota of intestine plays various important roles such as they prevent colonization of pathogens inside the body of an organism. They are also very important for proper digestion of complex carbohydrates for their easy breakdown. These bacteria play an important role in the immune system of the body. Prolonged treatment of antibiotics leads to the destruction and removal of normal microbiota.
Explanation of Solution
Normal microbiota of intestine performs a variety of useful function such as they help in digestion of food particles into simple compounds. They also prevent individual’s body from harmful pathogens and maintain immune responses of the body. If a person is exposed to long term treatment of antibiotics, normal microbiota of body effects in several ways. For restoring normal microbiota probiotics can be taken. These probiotics would help in restoring gut flora following antibiotics. One week probiotics treatment should be given to the patient if he or she is on prolonged antibiotic treatment. Several doses which are sufficient for rebuilding the glycocalyx (a component of the cell wall) can be given for further restoration.
Two ways by which intestinal microbiota and some representative species could be returned are described as below:
(1) For normal microbiota, consumption of probiotics is generally advised in most cases. These probiotics would not show any side effects and can be effectively taken for restoring microbial flora.
(2) Consumption of fiber-rich food is also advised for the restoration of some representative species.

- 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.arrow_forwardThe patient was an 80-year-old female who 10 days previously had had a cystocele repair performed. At the time of the hospital admission, a urine culture was obtained and revealed >100,000 CFU/ml of an Escherichia coli strain that was susceptible to all antimicrobial agents against which it was tested. Postoperatively, she began a 7-day course of oral cephalexin. She was discharged after an uneventful postoperative course of 3 days. Ten days postoperatively, she presented with a 3-day history of diarrhea. The patient noted multiple watery, loose stools without blood, crampy abdominal pain, and vomiting. She presented with a temperature of 38.2 degrees C, pulse rate of 90/min, respiration rate of 20/min, and blood pressure of 116/53mm Hg. Her white blood cell count was normal, but a large number (53%) of immature polymorphonuclear cells were seen. Physical examination, electrolytes, liver enzymes, and lipase were all within normal limits. Cultures for Salmonella, Shigella, Yersinia,…arrow_forwardMost healthy and some abnormal gut microbiomes that have a high diversity of taxonomic groups are resistant to manipulation by probiotics and other therapeutic treatments such a fecal transplantation. Explain why these microbiomes are more likely to be resistant to manipulation.arrow_forward
- A newly admitted patient reports a penicillin allery. The prescriber has ordered a second-eneration cephalosporin as part of the therapy. Which nursin action is appropriate?a) Call the prescriber to clarify the order because of the patient’s allery.b )Give the medication, and monitor for adverse effects.c) Ask the pharmacy to chane the order to a first-eneration cephalosporin.d )Administer the dru with a nonsteroidal antiinflammatory dru to reduce adverse effectsarrow_forwardMethicillin-resistant Staphylococcus aureus (MRSA) is one of the most dangerous organisms that can be encountered in the health care setting. MRSA is often resistant to more than one antibiotic. 1. What does it mean to say that S. aureus is resistant to methicillin? 2. What antibiotic would you choose to combat this micro-organism? 3. What are some clinical consequences for the patient infected with MRSA?

Mucosal surfaces are better than skin surfaces at supporting colonization by commensal microorganisms. b. The skin provides a larger surface area than mucosal surfaces for commensal microorganisms. c. There are ten times as many bacteria residing in the intestinal tract than the number of cells in the human body. d. It is common for commensal bacteria to live in symbiosis with their human hosts. e. During gestation in mammals, a fetus does not have any commensal microorganisms on their skin or mucosal surfaces.arrow_forward
- The World Health Organization (WHO, 2017) haslisted six steps individualscan take to prevent and control the spread of antibiotic resistance. a.One of the recommendations is “Never demand antibiotics if your health worker says you don’t need them.”Explain why when you have a flu, your health care worker would say that you do not need antibiotics. What are the other five recommendations?arrow_forwardWhy does Helicobacter pylori cause ulceractions in the lining of the Stomach? 1)The microbes secrete a toxin that prevents the host from detecting invasion of the microbe and thus allows it to thrive in the stomach and damage the host cells. 2)After invasion of the microbe in the cells lining the stomach, they are no longer able to produce mucous to protect the host cells from acid erosion 3)The microbe produces an enzyme that causes the cell to produce potent digestive enzymes that erode the stomach lining. 4)Once the microbe has entered the stomach, it releases digestive enzymes that degrade the mucous secreting cells.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
