Bacteria Essay Examples and Topics

The process of mono- and di- hybrid crosses is a main example of how each species can express their phenotypic characteristics. For these evaluations to be accurately tested for, the model organism that is used is Drosophila melanogaster. This model organism has a quick lifecycle…

For organisms to be able to adapt in this ever-changing world, one must evolve. Evolution, however, is not as simple as it seems, it is a battle between species, species battle it out and the species more willing to change wins, and it looks like…

The nineteenth century author, Charles Dickens wrote of Tuberculosis that it is, “a disease which medicine never cured, wealth warded off, or poverty could boast exemption from – which sometimes moves in giant strides, and sometimes at a tardy sluggish pace, but, slow or quick,…

It’s simply known as typhoid, it is a bacterial infection due to a specific type of Salmonella particularly, Salmonella enterica subsp. enterica serovar Typhi growing in the intestines and blood. Typhoid can be spread by eating or drinking food or water contaminated with the faeces of an infected person.  The risk factors include poor sanitation and poor…

Bacteria are invisible to the naked eye, yet hold the potential to bring down entire organisms. Bacteria can affect a wide range of organisms, but most are specified to a particular species. My personal encounter with the bacteria was with E. coli. More specifically, the…

We are surrounded by a lot of bacteria in the world that could potentially enter our bodies and create harm or good for the immune system. Although our bodies are balanced with good and bad bacteria, Tuberculosis is not a bacteria that you would want…

Streptococcus Pneumoniae A wide variety of bacteria, viruses, and fungi can cause Pneumonia which is present in the air we breathe. An important step in getting the proper treatment is identifying the cause of your pneumonia. Bacterial pneumonia is the most common type of pneumococcal…

Salmonella spp The Salmonella bacterium is a rod-shaped motile bacterium that posesses a flagellum. A flagellum is a long thin tail that helps the bacterium to move Salmonella reproduces asexually with binary fission. Binary fission has four steps: First the cell elongates and makes a…

Numerous cultures isolated from different sites of infections such as blood, cerebrospinal fluid (CSF), urine, pus, stool and many more are routinely measured through a microbial profile and antibiogram. The results of the microbial profile and antibiogram of these cultures isolated are applicable in diagnosing…

There are around 99 thousand organisms that are known within the fungi kingdom, such as mould, rust and mushrooms. Some fungi are found living freely in either water or soil, while others choose to form parasitic relationships with animals or plants. There are large amounts…

The pathogen of salmonellosis is Enterobacteriaceae and Gram-negative bacilli. It comprise two species: S. enterica, which is subdivided into over 2,000 serovars, and S. bongori. Also, based on genetic similarity and host range, the species has been divided into six subspecies: enterica (Group 1), salamae…

Sea food is one of a the main sources of low calorie animal protein and a source of nutrients and minerals. However, sea food can accumulate contaminates from the environment and food. These contaminants may be pathogenic bacteria or heavy metals. The studies indicate the…

If you are unfamiliar with the ‘CRISPR-Cas9’ system, it is the revolutionary technique discovered in bacteria (E. Coli) which they use to defend themselves against invading viruses. It works by the specific targeting of viral DNA and cleaves at determined locations, previously invading viral pathogens…

Meningitis can affect people of all ages; however, infants at 6-18 months of age are at an increased risk for developing bacterial meningitis. Elderly people are also at risk due to their decline in immune functions, as well as people with illnesses which affects their…

The purpose of these experiments is to view bacterial cells under a microscope by staining the cells and accommodating their characteristics with the stains used as different bacteria cells have different characteristics, depending on the environment in which they are exposed in. Experiment 4 covers…
