Title: Which Antibiotics Kill the Most Bacteria? Caroline Gorman April 2, 2016 HB bl. 6 Purpose: The purpose of this lab was to determine which of five common antibiotics would kill the Rhodococcus rhodochrous bacteria. Hypothesis: Out of the five tested antibiotics, doxycycline will kill the most Rhodococcus rhodochrous because it is generally used to treat mild infections. This will be tested by spreading the bacteria on agar in a Petri dish and adding a small amount of each antibiotic…

coli, in a water source is an indication of the presence human or animal waste matter in the water. These bacteria are a type of fecal coliform bacteria found in the intestines of humans and animals. Drinking water that contains E. coli bacteria may cause diarrhea, abdominal cramps, headaches and nausea. Young children and elderly people may be more susceptible to the adverse effects of E. coli because their immune systems are delicate. Polluted…

Discussion: The isolate studied was tested for innate antibiotic function on the following media: AC, LB, and 10% TSA. The ESKAPE relative strain that presented a response to the isolate was B.subtilis. In all cases except for that of LB, the isolate showed antibiotic qualities towards B.subtilis by presenting a zone of clearance on AC and 10% TSA media. This behavior is shown in Figures 4, 5, and 6.In the case with LB, B.subtilis inhibited the growth of the isolate as depicted by the empty…

Gathered from the data, it seems that commercial products are more effective than natural remedies; natural remedies made little if no contribution in inhibiting bacteria. This result however, does not signify that natural remedies are inadequate at inhibiting bacteria. It reflects that natural remedies are ineffective in inhibiting gram-positive bacteria. First natural product: Saliva for instance, is one of the body’s many defence mechanisms. Its main function is to prevent adhesion of…

It is a pattern today to go to the lavatory with your cell phone or tablet or else we are exhausted while we are in the washroom. We will read something while sitting on the can and so on. However, that is very not great and it can be truly undesirable, and this article will clarify you why is that so.We truly need to comprehend that germs can be discovered wherever in the restroom keeping in mind we are there sitting on the latrine and perusing something on the cell phone or tablet, those…

Salmonella infection in food is the one of the major causes of foodborne illnesses including fever, abdominal pain, diarrhea, and nausea. Thus, early detection of Salmonella contamination is important for our healthy life. Conventional detection methods for the food contamination have limitations in sensitivity and rapidity, thus the early phase detection has been difficult. Herein, we developed a bioelectronic nose using a carbon nanotube (CNT) field-effect transistor (FET) functionalized with…

1. One of the main topics could be the drug resistance mechanisms of bacteria. 2. First, spontaneous mutation which changes the drug target or upregulate drug efflux. Second, Horizontal gene transfer (HGT) that the genes in bacteria acquire to become resistant. HGT can cause multidrug resistance in a genetic event which make the bacteria become resistance. Third, the ability of bacteria that they can form biofilm while they are being infected. The bacteria provide themselves protection to…

Mary Farmer has Gram-positive cocci, Streptococcus aureus, and Brian Evans has Gram-negative bacilli, Escherichia coli. From this, we know that Culture A’s bacteria has a thick cell wall with no outer membrane and Culture B has a thin cell wall with an outer membrane. From the results of the Gram’s test, neither patient is infected with more than one strain and…

of inhibition which has a diameter range of 7mm to 10mm. In this study, the extract of hexane of S.aromaticum showed positive antibacterial properties against E. coli, and S. aureus for concentrations of 25, 50, 75, 100. The methanol extract showed positive against S. aureus for 75 and 100 mg/ml. The DCM extract showed positive for E. coli, S. aureus, (100 mg/ml). The comparison of the three extracts of clove oil shows that the hexane extract of clove oil has the highest zone of inhibition with…

The human gut contains numerous organisms including bacteria, viruses and fungi. These gut microbes have co-evolved with host through for a very long time and at baseline, provide a beneficial relationship with the host. This paper will focus on bacteria, which are multiple factors more than human cells in number. These bacteria have a significant effect on humans and play a significant role in maintaining one’s health. Despite the countless research projects that target these bacteria, their…
