Abstract Some bacteria are able to go through transformation making new combinations of genes. Transformation is a way of gene variability in bacteria. This experiment is based on the transformation mechanism of bacteria and gene regulation. The bacteria used for the experiment was Escherichia coli …

Pathogens are everywhere. They are in people, animals, and the environment. Pathogens come in a wide variety. The types are fungal, bacterial, viral, and other parasites. All pathogens can be dangerous, but two of them are more dangerous. These two types that more dangerous are …

Different types of bacteria in various forms are found all around us, and it is a microbiologist’s job to be able to identify these bacteria. Using various staining techniques and physiological tests, an isolated bacterium can be identified. In this experiment, a single bacterial colony …

Evaluation of the Evidence The modern version of the endosymbiosis hypothesis was developed and promoted by Dr. Lynn Margulis in 1970. The term endosymbiosis comes from “endo” meaning “within,” and symbiosis which occurs when two different species benefit from living and working together (Genetic Science …

Background: In Jane Horack’s article “Staphylococcus epidermidis”, S. epidermidis is described as “gram-positive cocci bacteria that are part of the normal flora on the skin and nasal passages. ” The article goes on to say that the species was originally named Staphylococcus Albus by microbiologist …

Poultry industry is one of the fastest growing sector in India. Poultry occupies a unique position in the livestock economy of India characterized by coexistence of intense (technology, capital, scale) with integrated production, marketing and the others based on the traditional knowledge and practices.

Introduction Bacteriophage which is also known as bacteria eater refers to viruses that infect bacteria.Bacteriophages are known to only replicate within host cells and must attach to a specific receptor on the surface of a bacteria cell to initiate infection. The contact between the phage …

Abstraction The demands for unvarying cloths are under different industrial environment, supplying attention, freshness, comfort and protection for the tegument. The survey besides saw types and consequence of bug every bit good as chemicals used to protect the unvarying cloths against their onslaught under the …

After suffering a lot of devastating epidemic attacks and mass deaths, humanity invented antibiotics and started applying them against known bacterial diseases. Using antibiotics for the last 6 decades, we are now facing the results of the process caused by genetic changes and mutations in …

When it comes to discussing bacteria, many people are not aware that not all bacteria are harmful. In fact, a substantial amount of bacteria that exists are very beneficial, and they actually help us rather than harm us. Bacillus Subtilis is one of these bacterium’s …

Humans are engaged in a “micro-war” with bacteria, and we are losing.  Bacteria represent one of the most adaptable organisms on the planet primarily due to their propensity for adopting genetic mutations. (more…)

An attack of bacterial meningitis can be devastating because most of its victims are usually children or infants. The symptoms of the disease can also be misread leading to improper or inadequate treatment with fatal consequences. As risks of misdiagnosis are many, it is recommended …

The beaches are considered as important recreational resources. The recreational activities performed at beaches involve a physical contact with water, such as sail-boarding and swimming. There is always a risk of having an accidental injury but apart from that people also face major health problems …

The word ‘bacteria’ is normally associated with disease-causing organisms, like the Streptococcus bacteria. While there are a considerable number of pathogenic bacteria that are notorious for such diseases as cholera, tuberculosis, and gonorrhea, such disease-causing species are a comparatively tiny fraction of the bacteria as …

Bacteria are often the cause of various diseases that humans suffer from. They become one of the major factors of human mortality if not properly addressed. This is the reason why it is essential that people are properly informed about the effects of these bacteria …

We calibrated three different molarities of copper (II) nitrate. We tested for the %Transmittance of 1M, 0. 1M, and 0. 01M and plotted the data collected on a calibration curve based on concentration and absorbance. We used nitric acid to dissolve a penny to produce …

Genetic transformation is due to a direct cause in the change by genes, due to the cell in taking and expressing traits from a separate piece of DNA. Naturally proficient bacteria are able to absorb exogenous DNA and go through genetic transformation. (Chen & Dubnau, …
