Step by step
Solved in 2 steps
- A 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?Why is it only necessary to include the exotoxin (in toxoid form) in vaccines for tetanus and botulism?Which of the following accurately reflects the information in this snip? When Staphylococcus aureus divides in two, it can produce either MRSA or MSSA. MRSA and MSSA are both types of Staphylococcus aureus. It is reasonable to assume that MSSA is harmless but that MRSA is a very serious disease.
- Bacteria have a single circular chromosome while human cells have 46 linear chromosomes. This means bacteria are considered half lloyd having only one copy of each gene.Mycobacterium tuberculosis microbes are not easily killed by sunlight or drying. This is because this microbe forms spores as a protective mechanism. True FalseA child presents with yellow crusting lesions on the arms and legs. It is determined that this is being caused by Streptococcus pyogenes. In what ways is the organism Streptococcus pyogenes different from Staphylococcus aureus?
- 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)Semi-synthetic and extended-spectrum penicillins have proven more effective than natural penicillins for two of the following reasons: 1-Interfere more effectively with the development of the peptidoglycan layer in cell-walls 2-Are less sensitive to penicillinases than natural penicillins 3-Do not contain the b-lactam ring thus making them less susceptible to b-lactamases 4-Are less susceptible to the development of resistance 5-Have a broader spectrum of activityUnder what conditions does Staphylococcus epidermidis become an opportunistic pathogen? Group of answer choices S. epidermidis can form biofilms on devices inserted into patients during surgery. S. epidermidis becomes pathogenic when it overgrows in the throat. S. epidermidis becomes pathogenic when it produces Shiga toxin. S. epidermidis becomes a pathogen whenever a patient has untreated diabetes.
- Can caffeic acid be used to treat cytomegalovirus CMV? Explain.A patient is diagnosed with malignant Hymenolepis nana and HIV. The patient's CD4 cell count is 28 cells per cubic millimeter and the patient is nonadherent to HIV drugs. Why or why not would albendazole be effective in this case?Your 66-pound patient is receiving Keflex (cephalexin) PO every six hours for impetigo. The recommended safe dose range is 25-100 mg/kg/day. The ordered dose is 500 mg PO every 6 hours. Does this dose fall within the recommended safe dose range?
