- Anaerobic bacteria produces which of the following inhibitory toxic product? -methilane -cyanide oxides -fatty acids -sulphidesIf a bacteria was found to survive very well in a pond of strong acid, but died quickly when exposed to air, this bacteria may be considered....? Aerobic Anaerobic Pathogenic E. coliYour supervisor contacts you to tell you that your recommended antimicrobic treatment did not work and the patient is still sick. Your supervisor thinks you may have misidentified the organism or that the organism was actually resistant to the antimicrobic. Write a follow-up paragraph to explain:- What may have gone wrong in your identification or choice of antimicrobic? - How could you convince your supervisor that your initial conclusion is accurate?
- Which of the following is NOT a property of an antimicrobial agent? a. Must have a known concentration over a period of time required to eliminate a pathogen b. all choices are correct c. must be selectively toxic d. Must have a favorable chemotherapeutic indexclostridium botulinum is a bacterium usually present in soil that may cause botulism. Briefly explain why one or few cells of a pathogenic bacterium, such as clostridium botulism, by itself typically does not secrete a toxin, despite the species as a whole being characterized as toxin producing.In some cases, why does a chemical is more effective as a microbicide when it is diluted rather than full strength?
