Bacteria react to a sudden change in their environment by expressing or repressing the expression of a whole lost of genes. This response changes the properties of both the interior of the organism and its surface chemistry. A well-known example of this adaptation is the so-called heat shock response of Escherichia coli .

Enterobacteriaceae is a family of bacteriathat can cause serious infections of the: 1. urinary tract 2. bloodstream 3. wounds These bacteria can also cause pneumonia. Some of these bacteria have developed resistanceto almost all available antibiotics, making these infections difficult to treat.
N. gonorrhoeae is a species of bacteria that causes the sexually transmitted infection (STI), gonorrhea. Not all of these infections are drug-resistant, but N. gonorrhoeae has developed resistanceto nearly all of the antibiotics that doctors use to treat the infection.
Acinetobacter is a group of bacteria that is commonly presentin soil and water. This group of bacteria can cause infections in a person’s: 1. blood 2. urinary tract 3. lungs 4. wounds Infections with Acinetobacter commonly occurin patients in healthcare settings and intensive care units. These infections commonly affect people: 1. with weakened imm...
P. aeruginosa bacteria can cause mild illnesses, such as ear infections and skin rashes. However, if a person has a weakened immune system, they may develop severe infections in their bloodstream or contract pneumonia. This can occur in people in hospitals with wounds from surgery or who are using breathing machines or catheters. Some strains of P....
Salmonella is a type of bacteria that can cause: 1. diarrhea 2. fever 3. abdominal cramps Some strains of Salmonella are resistant to antibiotics, which can cause infections to become more severe. More severe Salmonella infections can spread to a person’s bloodstream and may become life threatening.
Nov 20, 2019 · The human immune system is complex and adaptively responds to new encounters with bacterial pathogens. In turn, bacterial pathogens possess innovative adaptive strategies to evade and...

Sep 9, 2021 · In this section, we focus on 2 primary examples of adapt-and-live mutations, in which genetic adaptations that occur during infection prolong bacterial survival, either through transmission to new hosts or through the establishment of chronic infection.

Oct 21, 2021 · Abstract. Bacterial species can adapt to significant changes in their environment by mutation followed by selection, a phenomenon known as “adaptive evolution.” With the development of bioinformatics and genetic engineering, research on adaptive evolution has progressed rapidly, as have applications of the process.

Jun 26, 2018 · Apparently most pathogenic microorganisms have the capability of developing resistance to at least some antimicrobial agents. The main mechanisms of resistance are: limiting uptake of a drug, modification of a drug target, inactivation of a drug, and active efflux of a drug.
