Step by step
Solved in 2 steps
- Normal microbiota provide protection from infection in each of the following ways EXCEPT: Question 3 options: A) they produce antibacterial chemicals. B) they compete with pathogens for nutrients. C) they make the chemical environment unsuitable for nonresident bacteria. D) they produce lysozyme.The question below is one question I just separated the question marks 1) How are antibiotics, as a class of drugs, unique? 2)How does this facilitate resistance? 3)How are antibiotics misused?What could the overuse of anti-bacterial agents lead to?
- Which one(s) is/are more harmful to the host and why? A) Antifungal agents B) antiprotozoal agents C) antibiotics A and BWhich of the following virulence factors among A-D is correctly matched with its definition or characterization? A) O Invasins: pathogen proteins that prevent opsonization of the pathogen B) O Phase variation: allows pathogen to switch between different forms of an extracellular antigen (e.g., flagellum) C) O Protein A. a microbial factor that allows for attachment, typically a surface protein or surface glycoprotein D) O Prevention of lysosome:phagosome fusion mechanism employed by an extracellular pathogen E) OM protein, Opa protein: enzymes that interfere with the functioning of antibodiesWhich immunization is recommended to protect against the bacterium Haemophilus influenzae type b (Hib), which can cause meningitis and pneumonia? A) HPV vaccine B) Hib vaccine C) Hepatitis B vaccine D) DTaP vaccine
- Opportunistic pathogens are least likely to affect which of the following groups?a) AIDS patientsb) Cancer patientsc) College studentsd) Drug addictse) Transplant recipientsBelow are a list of virulence factors/ strategies paired with an example of an organism that utilizes them. How do each of the following strategies contribute to the virulence of the pathogen? Strategy - Causes the host to produce more receptors (Organism - Rhinovirus) Strategy - Produces gas as a product of fermentation (Organism - Clostridium perfringens) Strategy - Produces a capsule (organism - Klebsiella pneumonia) Strategy - Ability to move between adjacent cells (organism - Cytomegalovirus) Strategy - Ability to use pilus as a motility structure (organism - Pseudomonas aerogenosa)Why is it necessary to develop new generations of antimicrobial medications?
