There 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. How can a prion replicate itself without genetic material?
The worldwide spread ofmultidrug-resistant (MDR) pathogenicbacteria has becomean urgent threat to human and animalhealth. More than two million people inthe United States become infected withantibiotic-resistant bacteria each year, andmore than 23,000 of them will die fromtheir infections. In 2015, approximately480,000 cases of MDR tuberculosisoccurred worldwide and another 100,000cases were resistant to at least one antibiotic.In the United States, cases of drugresistantenterobacteriaceae infectionsincreased three-fold between 2001 and2012. In 2016, a woman in Nevada died ofa Klebsiella pneumoniae infection caused bya strain that was resistant to 26 differentantibiotics, including colistin, which is consideredthe “last resort” antibiotic.One factor leading to the spread ofMDR bacteria is the selective pressurebrought about by repeated exposure toantibiotics. Worldwide, livestock consume used as feed supplements. The routineuse of antibiotics in livestock feed and theoveruse of human…
What do you mean by antibiotic resistance? use youe own words to explain
Because of overuse of antibiotics and/or weakened governmental surveillance of infectious disease, several diseasesthat had been thought to be no longer a threat to humanhealth (e.g., pneumonia and tuberculosis) are rapidly becoming unmanageable. In several instances, so-called superbugs(microorganisms that are resistant to almost all known antibiotics) have been detected. How did this circumstancearise? What will happen if this process continues?

Hi i’m supposed to write a short essay on how evolution and microbiology relates to antibiotic resistance, but i don’t know where to start
Katelyn had been working for Dr. Johnson for a month, and while she had become quite good at measuring inhibitionzones, she didn’t know why she was doing all this work. She had gotten very curious after she began doing all themeasurements on a new set of antibiotics. # is experiment involved infecting mice with MRSA and tracking how theMRSA grew over time.Data were collected by counting the cells of MRSA taken from $ uid samples from the mice. # e cells were measuredby taking one gram of the $ uid and spreading it over plates, but now Katelyn counted the colonies that grew on theplate after 24 hours. Because there were so many, she actually measured the colonies as “log CFU/g.” A CFU is acolony forming unit, or essentially a cell that will divide into a colony that can be seen. Because there can be so many,Katelyn measured them on a logarithmic (log) scale. # e raw data in her lab notebook looked like the following:Table 1. E% ect of treatment on MRSA in mice after 24 hours of drug…
This article highlights a young doctor at Elmhurst Hospital during the beginning of Covid-19 pandemic. Dr. Zikry is quoted as saying: “It’s become very clear to me what a socioeconomic disease this is...”. In addition, the textbook discusses the personal variables and socioeconomic status (SES) that are used to find patterns in disease (pp.112-118). What do you think Dr. Zikry meant by referring to the SES of his patients? Why was it important to find a pattern of personal variables and SES among the of victims of Covid-19 at the beginning of the pandemic?

Why antibiotic resistant is a threat to the world?
In 1887 a strange nerve disease attacked the people in the Dutch East Indies. The disease was beriberi.Symptoms of the disease include weakness and loss of appetite, victims often died of heart failure.Scientists thought the disease might be caused by bacteria. They injected chickens with bacteria fromthe blood of patients with beriberi. The injected chickens became sick. However, so did a group ofchickens that were not injected with bacteria.One of the scientists, Dr. Eijkman, designed a new experiment based on his ownobservations. Before the experiment, all the chickens had eaten whole-grain rice, butduring the experiment, the chickens were fed polished rice. Dr. Eijkman researchedthis interesting case and found that polished rice lacked thiamine, a vitamin necessaryfor good health.1. State the question or problem that Dr. Eijkman investigated. 2. What was the original hypothesis? 3. What was the manipulated (independent) variable and the responding (dependent) variable? 4. Write a…
