In some occasions, you will have to write an essay in the extremely short amount of time on the exam in college or high school. Also, you may be a little bit of a procrastinator, and find yourself in a situation when the paper is due tomorrow morning, and you have not even chosen the topic yet. Even though a last-minute essay cannot look as great as a work prepared successively and carefully within the whole time given, you still have a chance to submit a decent paper. The working process will require your full attention and a lot of effort, even if you are assigned a simple essay. However, if you learn the next few tips, the essay writing will seem significantly easier and feasible even when you are short on time.

Firstly, clean up your working space to get started. Make sure you have everything you need on the table, take a pen, a few sticky notes, your laptop, and read through the assignment requirements. In case no prompt is given, search for good essay topics, and pick a few uncommon and interesting ones you will be able to write about. Making a final choice, think which topic is the most relevant to your current studies and will not take too much to research.

Afterwards, look for the most trustworthy sources or the ones you are certainly allowed to use. If you are not sure, access the online library or any free services where you can look for the books and articles for your essay. Use sticky notes to write down the information and put them in front of you to see how much data has been gathered and if you need to continue researching. Reread these notes from time to time and cross out the info you do not find relevant anymore.

When you have the data you need to produce a quality work, it is crucial to think about the structure of the future paper. If you are not sure how to write an essay outline properly, check what your essay type is first. Each type is organized differently, so you need to look up the structure every time you are given an essay homework. You can also search for an example of the essay on your topic, and adhere to its outline. No matter what kind of essay you are going to write, it is important to start with a thesis statement. It should declare what problem you will review in the paper, and which facts or arguments you will use to do it professionally. As these arguments will be discussed in the main part of the essay, outline the body paragraphs and put down a few sentences with the rough description of each paragraph. Think of the way you will engage the reader in the introduction, and which thought will be conclusive for the paper. When the direction of the work is clear from the outline, use it to draft the first version of the essay.

If you are not used to model essay writing, do not worry - your draft should not necessarily look like a masterpiece. It is only the depiction of your thoughts, and as you will have them written down, it will be easier to create a good essay. There is no best way to write an essay, so trust the working methods you usually use. You may like taking short breaks once in a few minutes, or write everything in one sit - just make sure to keep the focus on writing and avoid the urge to call a friend or watch something online. Thus, you will finish the paper faster, and will not feel guilty for engaging in other activities afterwards.

Do not forget to go through the essay a few times after the completion. Everyone makes typos and mistakes by accident, but it is about you to find and fix them before your teacher does. If you need help with an essay editing, try asking a friend or a family member to read and analyze your work. Also, you can order editing services in case your paper needs to be perfectly polished so that you can submit an ideal essay and get an excellent grade.

As these steps are simple to follow, you will not have any problems coping with an essay on time. Try the whole procedure at least once, and you will not have to use any other tips preparing an essay paper during your studies!

Does Staphylococcus aureus grow on bile esculin agar?

Some strains of Staphylococcus, Aerococcus and Listeria monocytogenes may grow in the presence of bile and hydrolyze esculin.

Does Staphylococcus aureus hydrolyze esculin?

Some strains of Staphylococcus, Aerococcus, and Listeria monocytogenes may grow in the presence of bile and hydrolyze esculin.

What Streptococcus are bile-esculin positive?

The bile-esculin test is widely used to differentiate enterococci and group D streptococci, which are bile tolerant and can hydrolyze esculin to esculetin, from non-group D viridans group streptococci, which grow poorly on bile.

Can Streptococcus hydrolyze esculin?

Enterococcus faecalis hydrolyzes esculin in the presence of bile and turns more than half the medium dark brown. This is a positive result. Streptococcus pyogenes does not hydrolyze esculin in the presence of bile.

What bacteria can hydrolyze esculin?

Principle of Bile-esculin test Bile-esculin test is based on the ability of certain bacteria, notably the group D streptococci and Enterococcus species, to hydrolyze esculin in the presence of bile (4% bile salts or 40% bile).

Is Staphylococcus epidermidis PYR positive or negative?

The SIG consists of three species: Staphylococcus intermedius, Staphylococcus pseudintermedius, and Staphylococcus delphini. Like the members of the SIG, Staphylococcus lugdunensis can test positive for both coagulase (latex agglutination testing) and PYR but is also ornithine decarboxylase positive.

What tests are used to identify Staphylococcus aureus?

Coagulase testing is the single most reliable method for identifying Staphylococcus aureus [9]. Coagulase production can be detected using either the slide coagulase test (SCT) or the tube coagulase test (TCT).

What test is used to distinguish between staphylococci and streptococci?

The catalase test is important in distinguishing streptococci (catalase-negative) staphylococci which are catalase positive. The test is performed by flooding an agar slant or broth culture with several drops of 3% hydrogen peroxide.

How can you differentiate between Streptococcus and enterococci?

Main Difference – Enterococcus vs Streptococcus Both Enterococcus and Streptococcus can be found in the mucous membrane of animals. The main difference between Enterococcus and Streptococcus is that Enterococcus is a common intestinal microbiota while Streptococcus is a common upper respiratory tract microbiota.

What test will differentiate an Enterococcus from a Streptococcus?

The PYR test is also used to differentiate the Enterococcus species, which are PYR positive, from the S. bovis group, which are PYR negative, which both carry the Lancefield group D antigen. Organisms resistant to SXT but susceptible to bacitracin can be presumptively identified as group A streptococci.

Is Staphylococcus aureus PYR positive?

aureus are catalase and coagulase positive, only SIG species are PYR positive. Both are negative for ornithine decarboxylase. However, an ornithine-positive Staphylococcus species that also gives a positive reaction in latex agglutination and PYR testing is Staphylococcus lugdunensis.

What is the difference between Staphylococcus aureus and Staphylococcus epidermidis?

The key difference between epidermidis and aureus is that Staphylococcus epidermidis is a non-haemolytic bacterium while Staphylococcus aureus is a haemolytic bacterium. Epidermidis and aureus are species names of two bacteria in the bacterial genus Staphylococcus.

What is the bile esculin test for Enterococcus?

The bile-esculin test is a biochemical test performed to differentiate Enterococci and group D Streptococci from non-group D viridans group Streptococci on the basis of their ability to hydrolyze esculin. Many organisms are capable of hydrolyzing esculin, but only a few of them can do so in the presence of bile (4% bile salts or 40% bile.).

How accurate is the bile esculin test?

It is a low-cost, rapid test with good sensitivity and specificity (>90%). Bile-esculin test is based on the ability of certain bacteria, notably the group D streptococci and Enterococcus species, to hydrolyze esculin in the presence of bile (4% bile salts or 40% bile).

What is the bile-esculin test?

Bile-esculin test is widely used to differentiate Enterococci and Non-enterococcus group D streptococci, which are bile tolerant and can hydrolyze esculin to esculetin, from non-group D viridans group streptococci, which grow poorly on bile. It is a low cost, rapid test with good sensitivity and specificity (>90%).

What is the composition of Bile Esculin Agar?

Bile esculin agar is a selective and differential medium which is used to presumptively identify enterococci and group D streptococci based on the ability of an organism to hydrolyze esculin. Beef extract (11 g), enzymatic digest of gelatin (34.5 g), esculin (1 g), ox bile (2 g), ferric ammonium citrate (0.5 g), agar (15 g), per 1000 mL, pH 6.6.
