Antibiotic resistance is a worldwide problem that happens when bacteria develop ways to combat the effects of the antibiotics designed to kill them. People do not become resistant to antibiotics. Instead, bacteria naturally develop mechanisms that make it difficult for antibiotics to kill them. For ...
Essentially this has been through rapid evolution leading to adaptability. All living organisms evolve. The speed at which they can do this is dependent on the generation time; for humans this is about 25 years whereas for bacteria it is often measured in minutes, sometimes as little as 20 mi...

according to the Science Education Resource Center at Carleton College. The test stains Gram-positive bacteria, or bacteria that do not have an outer membrane. Gram-negative bacteria, which do have an outer membrane, don't pick up the stain. For example,S. pneumoniaeis a Gram...
Sex pili helps in bacterial DNA transfer during bacterial conjugation 3. Capsule It is a viscous outermost layer surrounding the cell wall. It is composed of either polysaccharides or polypeptides of both (~2%) and water (~98%). They are present only in some species of bacteria. The capsule...
Name the process by which bacteria multiply themselves. What is the plural form of bacterium? Which classification of microorganisms contains protozoans fungi and parasites? What eats bacteria? How many kingdoms of bacteria are there? Classify all types of bacterial conjugation. ...
Natural compounds may also have such effects. A classic example is grapefruit, which contains a compound that inhibits the metabolism of many drugs. Many people who take prescription drugs, especiallystatins, avoid consuming grapefruit or its juice for this reason. Theherbal remedySaint John’s wo...
Conjugation, GeneticBacterial Physiological PhenomenaBiological EvolutionSexThough bacteria are predominantly asexual, the genetic information in their genomes can be expanded and modified through mechanisms that introduce DNA from outside sources. Bacterial sex differs from that of eukaryotes in that it is ...
What is represented by the small dots found in each of the bacteria cells? How can you distinguish between bacteria and protozoa? Assume the diameter of the field of vision in your microscope is 2 \; mm under low power. If one Bacillus cell is 2 \; \mu m, how many Bacillus ...
