Bacteria

motility, enzymes, etc.) we preform on the numerous bacteria in lab is to show any biological or chemical characteristics of the bacteria that may help it survive or adapt in the wild, how it may be useful or hazardous to humans, and use as general knowledge to differentiate bacteria from each other. In the Culture Media test we can use solid and liquid media to grow multiple bacteria in lab. It can help us determine what processes the bacteria can carry out, what nutrients may be needed or not…

After gram staining both the gram positive and gram-negative bacteria, the groupings were observed. For the unknown gram-positive bacteria, the cells were arranged in a cocci cluster, while in the gram-negative bacteria, the cells were arranged in a rod cluster. Both the gram negative and gram-positive bacteria exhibit a small yellow colony on the TSA plate. After 48 hours, the MSA plate was observed. Individual isolated colonies were found throughout the plate, with a yellowish color. The…

Staphylococcus aureus is a species of bacteria known as a major human pathogen causing a wide range of infections. Enterotoxigenic bacteria can be defined as bacteria that producing or pertaining in production of enterotoxin, thus enterotoxigenic Staphylococcus aureus is one of the bacteria that produce enterotoxin (Schelin et al., 2011). Most of previous research, an occurrence of enterotoxigenic S. aureus in food caused one the most frequent microbial diseases which known as Gastroenteritis…

The Tragedy We Created: Antibiotic Resistant Bacteria Antibiotic resistant bacteria, commonly known as superbugs, take credit for 700,000 fatalities every year. Out of the 700,000 annual deaths, 23,000 took place in the United States. Superbugs, defined as bacteria resistant to medication, exists as a festering boil on the face of modern medicine. Patients, doctors, and farmers alike play a role in allowing bacteria to have the upper-hand (The Antibiotic Resistance Crisis). Now more than ever,…

This section will be a narrative summary of the characteristic of my unknown bacterium that’ll touch base on the morphology, cell well structure, temperature tolerance, antibiotic resistance, physiology and other interesting experiment results. First is going through the morphology of my unknown bacterium; will be talking about the shape, cell wall structure, and other characteristic using the results from tests such as gram staining, simple staining, and spore staining. According to my lab…

tract, in a healthy body, the small intestine contains relatively low levels of bacteria. The large intestine contains approximately 10-100 billion bacterial organisms, and bacteria is supposed to be at its highest concentration in the colon. Compared to this number, the small intestine is relatively sterile (containing a mere 100 thousand organisms). However, in the case of SIBO, the highest concentration of bacteria is found in the small intestine, and this can cause serious health…

include different types of bacteria. Did you know that the crook of your elbow contains one million bacteria cells for every square centimeter? That is after being washed. (Marcela, 2008, n.p.). Most of the time when the word bacteria is mentioned, people think the worst. It is assumed that all bacteria are dangerous and that they often cause disease. However, scientists are discovering that not all bacteria are bad. The crevasse of the elbow houses many different tribes of bacteria, which are…

sequences in DNA. E. Coli was the bacteria that was first used to accept the plasmid known as pSC101 which was resistant to certain antibiotics (Genetics and Genomics Timeline). After repetition of this new process they decided to use the genes from the Xenopus laevis toad into E. Coli bacteria. They saw that the bacteria reproduced at an astonishing rate and recorded that the genetic material from the toad passed through different generations of E. Coli bacteria. Soon after these experiments,…

The objective of this lab was to isolate and identify an unknown Gram positive and Gram negative bacteria through the use of various microbiological techniques. The identification of the genus and species for the unknown culture should be obtained based on the characteristics for Gram positive and Gram negative bacteria. Bacteria are prokaryotic microorganisms that lack a nucleus and therefore all its genetic information is stored in the cytoplasm of the cell. The bacterial cell envelope…

Introduction: Bacteria create an enormous domain of prokaryote microorganisms that are diverse and abundant in most habitats on Earth. In fact, bacterial cells drastically outnumber somatic cells just on the external part of the human body compared to somatic cells within the whole body of a single individual. Bacteria are found just about anywhere on earth and are usually alongside other microorganisms including: mold spores or yeast cells, creating some difficulty when trying to distinguish…
