A Cure for Beriberi
In 1887, a strange nerve disease attacked the people in the Dutch East Indies. The disease was beriberi. Symptoms of the disease included 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 from the blood patients with beriberi. The injected chickens became sick. However, those groups of chickens that were not injected with bacteria also became sick.One of the scientists, Dr. Eijkman, noticed something. Before the experiment, all chickens had eaten whole grain rice, but during the experiment, the chickens were fed polished rice. Dr. Eijkman researched this interesting case. He found that polished rice lack thiamine, a vitamin necessary for good health.

In the last century, Paul Ehrlich dreamed of a “magic drug” that could eliminate pathogens while preserving the body cells' health.
Can you explain the specific actions of antibiotics to destroy bacteria?
Hana comes from an island town of 2000 people. She goes to the mainland with a friend and there they catch a highly contagious virus. A week after their return to their island-town, 8 people are infected. How many will be affected after another week? If there are 150 bacteria after 2 hours and 900 bacteria after 6 hours, how many bacteria were present initially? How many bacteria are there after 10 hours?

- It was not until 1928 that penicillin, the first true antibiotic, was discovered by Alexander Fleming, Professor of Bacteriology at St. Mary's Hospital in London. Penicillin heralded the dawn of the antibiotic age. Before its introduction there was no effective treatment for infections such as pneumonia, gonorrhea or rheumatic fever. Hospitals were full of people with blood poisoning contracted from a cut or a scratch, and doctors could do little for them but wait and hope. 1. What is the mechanism of action of penicillin? 2. Cells treated with penicillin do not die immediately, so how this antibiotic is effective? 3. Why penicillin is most effective against Gram-positive bacteria? 4. Explain penicillin resistance mechanisms among bacteria today and the causes why they gained this resistance and making this great life-saving drug not usable anymore.arrow_forwardImagine you are an astronaut and you are the first person to walk on Mars. You make the surprising discovery that there are "bacteria-like organisms" on Mars. Which of the following do not need to be true for you to consider these "bacteria-like organisms" as living? They must be able to reproduce. They must be able to respond to their environment. They must be able to transform energy. They must be able to move.arrow_forwardtwo ways bacteria are harmful and two ways they are helpful to humans?arrow_forward
- E. coli can cause various infections and food poisoning. How can people protect themselves from becoming sick with E. coli? On the other hand, many bacteria live in our digestive tract, including E. coli, are important in producing vitamins and enhancing our absorption of nutrients. They represent roughly around 3 Ibs of an adult's body weight, and some scientists call them a person's second brain. Antibiotics can kill both "good" and "bad" bacteria. What are some of the effects of antibiotics killing good bacteria? How does consuming acidophilus influence your normal intestinal flora? What are some of the things people do to take care of the "microbial friends" inside their guts?arrow_forwardDescribe one scenario in which antibiotic resistant bacteria in a chicken could enter your body.arrow_forwardDraw a prokaryotic cell and show the different target parts of the cell where antibiotics can attack.

- Antibiotic-resistant bacteria have become a stubborn challenge for scientists. Should bacteriophages be used to save the lives of patients in which other treatments have failed?arrow_forwardMany disease-causing microbes do not cause disease in every host. Describe a possible reason for why one person gets an infection from the same bacteria that doesn't affect other people.arrow_forwardSuppose you got ill. When you have come to the doctor,he gave you antibiotics medication without doing any kind of test. What do youthink about which type of microbe attacked the body?
