1. Amoxicillin works by inhibiting cell wall synthesis during the stage of active multiplication and is a broad spectrum drug. The organisms that we tested with Amoxicillin, both Gram + & - were all resistant to this drug. The Zone of Inhibition was 0mm for E. Coli, S. Aureus, P. aeruginosa, S. marcescens. 2. Ampicillin’s mode of action is to penetrate Gram + and some Gram – cells. It has an Amino group which helps it to penetrate the outer membrane of Gram- bacteria. It inhibits bacteria

animal glue, etc.) to achieve the adhesion between the particles and consequently to be applied as paint film on the dry ground. The pigment must be dispersed or grinded as evenly as possible in the binding medium to take full advantage of the properties of both the pigment and the binder.[8] The typical stratigraphic structure of the Egyptian wall paintings is usually made of multiple layers. The plastering procedure was to initially smooth an irregular rock surface with one or more of plaster layers

There was not any specific experience that made me want to be a vet tech, but I have known for many years now that I want to help people by working in medicine. Only within the past year or two have I considered becoming a vet tech so that I can work in medicine, help people, and work with and help better the lives of animals. Working with animals would be a huge plus. I have chosen to write about what it is like for a vet tech to work in a zoo (and hopefully other wildlife). I would love to make

Chickenpox was discovered years, years ago. According to an article on chickenpox (2008), Giovanni Filippo (1510-1580) was the first to have the first description of varicella (chickenpox). Around this time, people would mistake a mild smallpox for chickenpox. Later, in 1767, a physician named William Heberden, also from England, was the first physician to clearly demonstrate that chickenpox was different from smallpox (Chickenpox, 2008). Chickenpox is just one of many disesases that are caused by

Bacteria and viruses which are small organisms considered as the most common causes of the diseases and infections. They both have the incubation period inside the host which is neither symptoms nor signs appear. Viruses which is non living organisms have unique pathways that end up either with life or death. Measles as a type of the epidemic viruses has specific movement inside the body. The symptoms of the measles appear regularly depending on the activation of the virus. Indeed, “The majority

In table 1.1 we see that the negative control passed and there was no contamination. Since we saw growth this is indicating that no contamination was present. Otherwise, if the agar was contaminated, we wouldn’t see any changes or growth on these agars. If you were to look at tables 1.2-1.5 you’ll see signs of growth on the surfaces of the agars. In table 1.2 you’ll see that S. epidermidis showed an olive metallic streak with colonies and coagulase positive on the blood agar. The olive metallic

The purpose of this experiment was to work meticulously to find the most effective treatment for the Staphylococcus Aureus bacteria. However, it is crucial and advantageous to first have an understanding of the S. Aureus bacteria. Staphylococcus is a group of bunched up bacteria that can cause a variety of maladies. The name is derived from the Greek diction staphyle, which means a “bunch of grapes” (Harper, 2015). S. Aureus was first discovered and documented in the late 1880’s, causing a variety
