This determined which set of tests that had to be done. My bacterium turned out to be gram positive. When conducting these tests, I only had to do the coagulase test and the catalase test because when doing the catalase test, the reaction was that it had bubbled. If it did not bubble, or have a positive reaction, then I would not have had to do the coagulase test. Also, since my bacterium caused a positive catalase test, I only had to do the coagulase test and no other tests.
The ultimate objective of this report is to narrow down the possibilities of bacteria using a series of test, while eliminating unlikely choices. Using the skills in the microbiology lab you can discover and make a educated decision of determining the mystery microbe, with the enough supported information collected from the chemical test and stains. There will be 17 test that will be run, each of this test will bring an important clue in determining the Mystery Microbe based on their environmental
Since the p value was greater than the alpha level, it indicated that the results were not statistically significant (Bridge etal 2015). We did not reject the null hypothesis and reject our hypothesis. Based on the tables and graphs that were constructed, we were able to see that the sodium chloride acted as a hypertonic solution for the yam cores compared to the water (McGraw-Hill Education 2003). Although we were able to visually see a difference between the two solutions, it was not significant enough to reject the null hypothesis. Since a yam is a plant of the genus Dioscorea, it contains cells that are partially permeable membranes.
I hypothesized that the Conodoguinet Creek is polluted. Through my research I have found that the Conodoguinet Creek is not polluted. One reason it is not polluted is because most of the macroinvertebrates and crustaceans we found in the creek are pollution sensitive creatures. Another reason the creek is not polluted is the level of acidity and alkalinity is 7 which is a healthy number on the pH scale. If the acidity or alkalinity levels were high scientists would have to find a way to neutralize the acid and alkaline.
The slide was then rinsed and safranin was again used as a counterstain. Using oil immersion objective lens of the microscope, unknown #76 had only reddish-pink cells without any signs of spore formation. Thus the given unknown is a non-spore former. Bacillus subtilis was used for positive control and Escherichia coli for negative control for endospore
In the case of a phage turning against the immune system, a polyethylene glycol can be administered that reduces the immune response (Matsuzaki, par. 8). Current issues with phages are mostly based on issues that occurred in the past when little was known about the origin or abilities of the new bacteria. With modern medicine, each of this issues are simple to
As a result of vaccination, antibodies will be produced that attack the weakened virus without infection occurring as it would with natural infection. The antibodies will remain in the body and when exposure to the virus occurs the immune system will have a memory of how to fight it in the future. Despite the biological benefits of vaccinations, there is still debate on this topic. It is important that we understand where people 's doubts about vaccines lie and if they are valid or not. The main concerns people have with vaccines are that they are believed to be unsafe, ineffective and unnecessary, but is this
To fully avoid this error, many more plants should have been tested to see if trichomes really do have an effect. Errors were attempted to be avoided by completing trials of different plants. The different trials allowed for any errors in one to not matter in the whole experiment. When all the trails were averaged out much of the errors did not affect the average because not all of the errors were present for each
Nearly every time she introduces a scientist, she first uses a direct quotation from them and in the next sentence she states where they work. Although stating where the researcher is from builds credibility, it is not essential enough information to stand alone as s sentence. It could have been just as effective and more eloquent by stating these facts as subordinate clauses. In addition, a reader could easily be confused of determining which are the author’s own words and which are the paraphrase of scientists. For example, “Drugs such as colistin, which are so important for treating people, need to be withheld from use in animals — at least until absolutely necessary, he says” gives credibility to the scientist at the end of the sentence.
Also I would put more reaserch into the product of glo germ I use. Because I did not get a great product, it was kind of like lotion and washed off very easily. In addition I would also time how long I scrubbed, because time also affects how many germs are removed. Lastly my hypothesis
People believe that the green from the infection is mold but mold is not a human pathogen. The color comes from iron compounds. They usually do not cause infections in healthy people and if it does it is not as severe. What does the Bacterial like? Pseudomonas bacteria thrive in moist places, feeds off dead tissue and other bacteria and moisture allows it to grow.
In some older shots there was a preservative known as Thimerosal that was used in order to prevent bacteria and fungus from growing. (Frequently Asked Questions about Thimerosal. - 2015). Thimerosal is a ethylmercury organic compound and because people associate methylmercury in fish with health issues when ingest they believe that the mercury in the Thimerosal is also harmful. However, as shown by research by the CDC, there have been no direct correlations between vaccines with Thimerosal and autism.
