Concept explainers
To determine:
The chemical produced by the organism in the following illustration.
Concept introduction:
The illustration depicts the growth of bacteria on blood agar medium. Blood agar media is included under complex media as it has soybean meal and casein. This media also exhibits differential growth of microorganisms on a single media and brings major differences in different colonies; hence it is also a type of differential media. Microbes produce different types of toxins which are associated with causing diseases.
To determine:
The process by which this chemical add pathogenicity to an organism.
Concept introduction:
The illustration depicts the growth of bacteria on blood agar medium. Blood agar media is included under complex media as it has soybean meal and casein. This media also exhibits differential growth of microorganisms on a single media. The medium is used to grow a wide spectrum of microbes. The medium includes a mixture of nutrients which supports the growth of microorganisms.

Which of the following statements best describes why? a. All the microbes that were living inside the person’s body die when the person dies. b. Microbial populations grow and spread to different areas of the body after the person dies. c. Microbes in the body have fewer resources after the person dies, which increases competition. 2 Which of the following statements about cadavers (dead bodies) is most likely to be true? a. Microbial communities in and around a cadaver change over time. b. Samples taken from different cadavers always contain the same microbes. c. The microbial community found in a cadaver is very similar to the one found in a living body. 3 After death, gases build up inside the…arrow_forwardAs a medical microbiologist, if you are presented with a patient suspected to have a bacterial disease, describe the various steps you would follow, to establish a laboratory diagnosis.

After the building was evacuated and all of the potentially exposed workers had received antibiotics to prevent the establishment of infection, no one was sure how to disinfect the building to make it safe for the return of workers. Your team has been hired by the Management to develop a plan to decontaminate the Building Complex after the arrival of anthrax-laced letters. The Building Complex contains thousands of valuable documents that cannot be destroyed. Workers need to be able to return to the buildings, although they do not need to return immediately. You need to guarantee the safety of workers who return. a. Can you devise an experimental setting to test the effectiveness of your strategy?b. What advice would you give to workers concerned with contaminating their family members?arrow_forward
- Which of the following best describes COVID-19? Infectious disease Emerging infectious disease Pathogen Helmintharrow_forwardI need help answering this question to my professor: The topic for the discussion was this one: Some 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? My answer was this one: To reduce the spread of these pathogens an infection control protocol should be followed. Some ways in which this could be reduced is by using desinfectants, sterilization, hand washing, and disposing techniques. In addition, I currently work as a dental assistant at Jackson Main and the protocol we use is hand washing our hands for at least 20 seconds before and after seeing every patient. We use CaviWipes to disinfect every surface and autoclave every single instrument after every use. Also, we make sure to…arrow_forwardPlease reply to the post below whether or not you agree or disagree and why A common microbe found in foods and can be taken orally are probiotics. Probiotics are live bacteria that balance good and bad intestinal bacteria and aid in digestion or digestive problems. For example, Lactobacillus species habituate where rich carbohydrate substances are available including the human digestive and urinary tracts. In 1900 lactobacillus acidophilus was isolated by Moro from infant feces and the intestinal tract of animals and humans. Also, it was reported in the feces of milk fed infants and older persons consuming high milk/lactose diets. This microbe is also found in plant materials and agricultural products particularly milk, cheese, fermented milk products and beverages such as wine and cider. Historically, Lactobacillus species is most often known to be capable of eliciting beneficial effects on the microbiota of the gastrointestinal tract. It helps the body break down food, absorb…arrow_forward
- As a nurse supervisor working in a infectious disease ward facility you must know the infection prevention and control measures to prevent cross contamination. How will you consider that you are an expert, applying Patricia Benner's Novice to Expert Theory. Elaborate your answer.arrow_forwardPlease help. The terms germ and microbe are often used interchangeably. What comes to mind when you hear the word germ? The word biome can be defined as a major ecological community type such as a grassland or desert. Why is the term microbiome used to describe the microbes that live in or on the human body? Describe the benefits the microbe Bacteroides thetaiotaomicron provides to its host species. Helicobacter pylori was originally identified as a causative agent for ulcers in humans, but turns out its role is more complex. Describe how H. pylori also plays a role in regulating appetite. Describe the role that Bacteroides fragilis plays in controlling the human immune/inflammatory response.arrow_forwardEscherichia coli For each of the following, describe what information the field knows now and what additional questions the field still has opportunities to explore.
