- During the fall 2001 bioterrorist attack in which anthrax endospores were sent through the mail, one news commentator suggested that people should iron all their incoming mail with a regular household iron as a means of destroying endospores. Would you agree that this is a good way to disinfect mail? Explain your answer. Which disinfectant methods would be both more effective and more practical?commercial sterilization is designed to provide enough heat to destroy the endospores of what organism? a. clostridium tetani b. stapylococcus aureus c. prions d. bacillus anthracis e. clostridium botulinumSome potentially pathogenic bacteria and fungi, including strains of Enterococcus, Staphylococcus, Candida, and Aspergillus, can survive for one to three months on a variety of materials found in hospitals, including scrub suits, lab coats, plastic aprons, and computer keyboards. What can hospital personnel do to reduce the spread of these pathogens?
- Of what practical importance are air borne microorganisms to the laboratory workers? What precautions should be taken to control laboratory contaminants? Of what advantage is the using a solid and a liquid medium?placing bacteria at ultracold temperatures is as effective at killing microbes as the use of dry heat in incineration. is is true/false?If you spill a culture, how should you proceed in a microbiology lab?
- Would you be able to grow a sample obtained from a patient's wound (suspected to be infected with MRSA) on EMB? Explain.Which of the following agents if introduced into a growing culture of bacteria would halt growth but if removed would allow growth to continue? A) Antiseptic B) Bacteriostatic agent C) Disinfectant D) Bactericidal agent E) Sterilizing agentA patient is experiencing high fever and body aches from an infected skin wound. You suspect a bacterial infection and perform a Gram stain from a pustular exudate why are you able to rule out an ENDOTOXIN as the cause of the fever and from the image, which organism do you suspect? The bacteria is purple(+).
- Infections among hospitalized patients are often related to the presence of a medical device in the patient. Which conditions favor the formation of biofilms on in-dwelling catheters?Of what practical importance are air borne microorganisms to the laboratory workers? What precautions should be taken to control laboratory contaminants? Why are petri dishes incubated in an inverted position? Of what advantage is the using a solid and a liquid medium?A student inoculates Escherichia coli into two test tubes containing the same sterile liquid medium, except the first tube also contains a drop of a chemical disinfectant with an antimicrobial effect. After 24 hours of incubation, the first tube remains clear while the second tube becomes cloudy with bacteria. How would you go about determining if the chemical is bacteriostatic or bactericidal?
