An agar plate was flooded with a culture of a species of bacterium usually found in the mouth. Four steriled paper discs, A, B, C, and D, each containing a different brand of mouthwash, were then placed on the agar plate. The drawing shows the appearance of the plate after it had been incubated below body temperature for three days, this is to ensure that the bacteria are not harmful to humans. Describe the aseptic technique that would be used when flooding the agar plate with bacteria
the dirts and bacteria in the water would coagolate or clump together~it is also a method of purifying water..
The surface colonies on a pour plate larger than those within the medium especially aerobic bacteria within the medium would be a restriction of growth. The restriction of growth would be due to the lack of oxygen.
i. An anaerobic indicator. i. An anaerobic indicator. -anaerobic indicator, containing methylene blue, will turn white when oxygen is removed. if the bacteria grow while the anaerobic indicator is white then you know the bacteria is CAPABLE of anaerobic growth (growth in number, not size).
to inoculate an agar plate you would place bacteria on the agar to grow
The best test would be to take some of the bacteria growing on the LB plate and streak them on a LB/amp plate. If the bacteria are viable on the LB/amp plate, then they are resistant to ampicillin. If no bacterial colonies survive, then they were not ampicillin resistant.

Bacteria or viruses that could be rubbed off. Hand, foot and mouth disease for example. Really horrible I would know from having it personally, so stables and everything have to be kept disinfected.
If you transform bacteria with a plasmid containing a selection marker (such as an antibiotic resistance gene) and plate the transformed bacteria on a plate suited for selecting for plasmid-containing bacteria (such as a plate containing an antibiotic that only those bacteria with antibiotic resistance can survive), then simply inspecting whether colonies are present on the plate will suffice in determining whether the transformation succeeded. If no colonies are found, that means no bacteria got the antibiotic resistance gene on the plasmid and the transformation was unsuccessful. If some colonies are found, that means some bacteria contain the plamis containing the antibiotic resistance gene and those colonies can the transformation was successful.
Pericarditis, Endocarditis, and Myocarditis. All of these are inflammation diseases of the heart and if it is caused by bacteria, then it can be treated by antibiotics, because antibiotics clear up infections/bacteria.
Don't take me for certain here but as i remember hydrogen peroxide is used for healing and disinfecting. keeping a wound clean from bacteria and etc. So my best guess would be that it would keep your horse's wound disinfected and help it heal up better.
No because it would be to big for his or her mouth and it would have to be disinfected

The purpose of the spread-plate technique is to grow and isolate colonies of bacteria. A sample of bacteria is transferred to the agar plate, an environment that provides nourishment for the bacteria to grow. The bacteria sample is applied to the agar plate which a special streaking technique that dilutes the amount of bacteria in each section of the agar plate continuously. This is because if you just swabbed the bacteria onto the plate with no special technique the colonies would grow very densely together and be difficult to study. The streaking technique gradually dilutes the amount of bacteria in each 'quadrant' of the plate, so the last quadrant should have small, isolated colonies that can be easily studied. The spread plate technique is also used for the eneumeration of aerobic microorganisms from the given sample. This can be done by serial diluting the samples, placing 0.1ml of the diluted sample in the middle of an agar plate and spreading the sample over the surface with a help of an L-rod. After the incubation rhe colonies can be counted.
