After taking antibiotics for several weeks, a patient develops a severe bacterial infection in his intestines. The doctor claims

the antibiotics changed the microbiome of the patient’s gut, causing the infection to develop. What evidence would the doctor need to support the claim? Explain how competition and succession played a role in developing the bacterial infection.

Answer:

Before the antibiotic, the ‘good’ bacteria had colonized her intestines and formed colonies that made up her biome. These colonies out-compete other bacteria, including ‘bad’ bacteria that tried to grow in the intestines hence protecting her intestines from infection.

However, the antibiotics wiped out the established colonies of ‘good’ bacteria –destroying her biome- and gave room for recolonization of the intestines by bacteria. The secondary succession gave a chance for the ‘bad’ bacteria to also thrive and cause her massive infections.

Our intestines have a beneficial bacterial flora, that is, the bacteria present there do not affect our organism, but they do audit us in some functions. However, when a person has bacterial infection in the intestine, it means that that person has had their body invaded by harmful bacteria that are causing their illness. At this point, all of these bacteria begin to compete for space and food and many of them end up dying in the process.

However, when the patient takes antibiotics to end the infection, these drugs end up killing most of these bacteria, even the beneficial ones, leaving the intestine unbalanced and susceptible to bacteria resistant to this antibiotic.

Resistance happens, because some of these bacteria may not have been exposed correctly or environment, or have been exposed to a non-lethal dose, or have suffered some kind of mutation that makes them resist the drug. In this, the current natural selection, allowing non-resistant bacteria to die, while resistant ones survive and generate other resistant bacteria, creating a flora that is not attacked by the antibiotic.

If the harmful bacteria survive they will create a whole community of harmful bacteria that will cause an even more serious infection.

Denitrifying bacteria convert nitrate into _____, thus returning nitrogen to _____.
ziro4ka [17]

Denitrifying bacteria convert nitrate into <u>nitrogen gas</u>, thus returning nitrogen to the <u>atmosphere</u>.

Denitrifying bacteria- Numerous phyla are included in the broad class of bacteria known as denitrifying bacteria. This group of bacteria, which is a part of the nitrogen cycle, may carry out denitrification together with denitrifying fungi and archaea.

Phylum (Phyla)- In biology, a phylum is a rank or level of taxonomic categorization that comes after a kingdom but before a class. Although the nomenclature for algae, fungus, and plants is recognized by the International Code of Nomenclature as being equivalent, division rather than phylum has traditionally been used in botany.

predict what might happen to a population that is experiencing little immigration and emigration, low birth rate, and high death
bezimeni [28]
The population will later, cease to exist.

Since the population is experiencing (about) the same rates of immigration and emigration, these 2 factors will not change anything.

A low birth rate and a high death rate means that more people are dying than being born.

Therefore the population will decrease until there is nobody and it will cease to exist.
