- Which statements describe ways in which antibiotic resistant bacteria can spread? Health care workers become infected after have interacting with sick patients. Hospital visitors transfer resistant bacteria from patients to family or community members. Animals raised for meat or milk are routinely given antibiotics. Animal feces is used as a fertilizer for food crops. Antibacterial soaps are used at home, at schools, and in hospitals.The illustration best describes: A dormant bacterial infection A dormant viral infection An active bacterial infection An active viral infectionThe term "colonization" is best described as: a large group of unicellular organisms presence of bacteria on our body that may not necessarily cause harm a virus that will colonize bacteria and make the disease more virulent all of the above
- Which of the following are criteria for antibiotics? (select all that apply) Chemical substance produced by a microbe Kills viruses Stops the growth or kills other microorganisms Effective in small dosesRobert Koch developed a set of criteria (postulates) for conclusively demonstrating the aetiology (specific cause) of an infectious disease. Which of the following is not a postulate? The infectious agent must be isolated and cultured in vitro The disease is reproduced when a pure culture of the infectious agent is inoculated into a new susceptible host The infectious agent can be recovered from the experimentally-infected host The infectious agent is present in most cases of the diseaseKoch's Postulate proved that: normal flora are necessary for life some diseases are caused by microbes yeasts produce alcohol from sugar viruses are not cells
- Which of the following is an example of a noncommunicable infectious disease? infection with a respiratory virus food poisoning due to a preformed bacterial toxin in food skin infection acquired from a dog bite infection acquired from the stick of a contaminated needleTrue or false Alexander Fleming discovered the first antibiotics penicillin in the early 20th century. Bacterial and fungal infection can be readily cured by antibiotics. Mosquito transmits various infectious diseases including Malaria.Which type of pathogen is the easiest to destroy? Gram-negative bacilli Naked viruses Prions Gram-positive cocci Endospores
- Which one of the following statements regarding antibiotics is FALSE? It is a substance produced by microorganisms It is a substance produced totally by chemical synthesis It is a substance produced partially by chemical synthesis JEANETEN SEER E It is a substance produced by our immune system in response to a pathogen OIt kills or inhibits the growth of micro-organismsWe commonly use antibiotics to treat infections by which microbes? Choose all that apply. Group of answer choices Viruses Protozoa Fungi BacteriaWhich of the following is NOT true about Koch's postulates? First developed by Robert Koch, the pioneering German microbiologist In the first step, the microbe that causes a naturally occurring disease is cultured from a "wild" (non-laboratory) animal which has that disease None of the other four answers (All are true about Koch's Postulates) They represent a process for showing a causal association between a specific microbe and a disease If the same microbe from a diseased "wild" (non-laboratory) host causes the same disease in a lab animal and it can be cultured from that lab animal, this proves that the microbe is the cause of the naturally occurring disease
