Chapter 22, Problem 1VC
Summary Introduction
To determine:
The reason to not treat a patient having infection by E.coli STEC with powerful antibiotic.
Introduction:
Toxicity is defined as the degree to which a substance is harmful to humans or animals. Toxicity is of two types such as acute toxicity and chronic toxicity. Acute toxicity is caused by short exposure with harmful chemicals for short time. Chronic toxicity is caused due to long-term exposure to harmful chemicals.

Question 41
How can Clostridium tetani survive in aerobic environments?
Assume you work at the local hospital in your home town. Suddenly you notice that 10% of your patients are having serious staphylococcal infections. None of these patients were admitted for having a staphylococcal infection, and we assume that all standard infectious control procedures are being followed (hand washing, use of gloves and masks, etc.). Remember that a small percentage of bacteria do evade even the most scrupulous of infectious disease control procedures. How could you use what you have learned in this week’s laboratory to solve the problem?
How could you find out where the infection originated? What steps would you need to take?
How could you determine definitively what organism is causing these patients’ infections?
How could you determine how to treat these patients?
Once you determine the source of the infection, what ethical issues, if any, are involved here? What should you do to protect the privacy and welfare of the patients as well as avoiding conduct…
What new symptoms do you predict if the following exotoxins appeared in a new bacteria? Explain why you expect those symptoms.
1. A lower respiratory (lung) bacteria with the Cholera Toxin
2. A reproductive tract bacteria with the Exfoliative Toxin (ET)
3. A large intestine bacteria with Diptheria Toxin

- I 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_forwardThere have been recurring cases of mad-cow disease in the United Kingdom since the mid-1990s. Mad-cow disease is caused by a prion, an infectious particle that consists only of protein. In 1986, the media began reporting that cows all over England were dying from a mysterious disease. Initially, there was little interest in determining whether humans could be affected. For 10 years, the British government maintained that this unusual disease could not be transmitted to humans. However, in March 1996, the government did an about-face and announced that bovine spongiform encephalopathy (BSE), commonly known as mad-cow disease, can be transmitted to humans, where it is known as variant Creutzfeldt-Jakob disease (vCJD). As in cows, this disease eats away at the nervous system, destroying the brain and essentially turning it into a spongelike structure filled with holes. Victims experience dementia; confusion; loss of speech, sight, and hearing; convulsions; coma; and finally death. Prion diseases are always fatal, and there is no treatment. Precautionary measures taken in Britain to prevent this disease in humans may have begun too late. Many of the victims contracted it over a decade earlier, when the BSE epidemic began, and the incubation period is long (vCJD has an incubation period of 10 to 40 years). A recent study concluded that 1 in 2,000 people in Great Britain carry the abnormally folded protein that causes vCJD. In spite of these numbers, the death rate from vCJD remains low. It is not clear whether this means that the incubation period for the disease is much longer than previously thought, or whether they may never develop the disease.

- can you explain why Bacillus anthracis can be pathogenic in a mouse and not be fought off by the immune system? I need help finding the answer in the article and explain in short answer link to article: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC106848/arrow_forwardIdentifying an unknown bacterium is an essential step in the diagnosis and treatment process. Since not every antibiotic is effective against every type of bacteria, knowing what caused a particular infection allows us to make correct prescriptions so patients can recover more quickly. Knowing the cause of an infection also prevents antibiotic resistance as well, since incorrect prescriptions allow bacteria to be unnecessarily be exposed to antibiotics, increasing the chances of developing resistance.arrow_forwardWhat cells inside our bodies would be affected if you ingested a suspension of T4 phage?

If your organism is transmitted in a specific location or under certain circumstances be sure your patient has been to those locations or engaged in those behaviors that would lead to transmission Have the appropriate timeline in terms of incubation and length of illness. Cover the important symptoms. You do not have to give all possible symptoms, just the typical one. Provide some important laboratory test results without stating the name of your microorganism.
