Microorganism

in may seem clean, but evidences suggest that the hospitals are one of the most likely places to get infected while harboring numerous pathogens. During patients’ care, the hospital staff can also become contaminated and carry disease causing microorganisms. This may cause harmful infections in the patients entering hospitals who are already immune compromised [11]. So, hospital acquired infections or health care associated infections (HAI) are the contaminations that patients catch while being…

Bacteria A person with a cold can spread the infection by coughing and/or sneezing. Bacteria or viruses can be passed on by touching or shaking hands with another person. Touching food with dirty hands will also allow viruses or bacteria from the intestine to spread. Water bacteria needs water to dissolve the food they use for energy and growth. Energy sources such as sugars, starch, protein, fats and other compounds provide the nutrients. Oxygen some bacteria require oxygen to grow (anaerobes)…

The field of science fascinated me even throughout high school. In my Sophomore biology class we worked on a project involving microorganisms from a local pond and from that point forth I knew that this was my dream job. I asked my Biology teacher, Mr Goudy, if he knew how the job market looked for a microbiologist and when he said that it was a growing field, it only made my passion for the study intensify. He also informed me of the growing need due to bacteria developing resistances to the…

preservatives like salt and sugar are often used in preserving canned fruits, processed meats as well as various types of canned or jarred vegetables whereas chemical preservatives like benzoic acid and sorbets are used to prevent the growth of microorganism. Most recent preservatives i.e. artificial preservatives revolutionized the food industry in term of flavor, quality and storage. Food manufacturers use an array of food preservatives to keep food fresh and stable, as well as to extend shelf…

fowleri “is normally a free-living microscopic amoeba,” meaning that it can survive on its own without a host. This species is found most commonly in warm fresh waters and soil, where they make a living consuming other microorganisms such as bacteria (Naegleria). 2. Life-Cycle The life-cycle of N. fowleri is composed of three stages, trophozoite, flagellate, and cyst. There is no particular order for these stages, rather, each stage is entered in response to the amoeba…

Results: This study compared the antimicrobial effect of two herbal oils (Coconut and Nigella sativa oil) versus Chlorhexidine gluconate 0.2 % as gold standard on 3 types of oral cariogenic microorganisms (Streptococcus mutans, Lactobacilli and Candida albicans) 1- Streptococcus mutans: The results of this study showed that coconut oil had a statistically significant higher inhibitory effect on SM with decrease in number of CFU from 500 to 40 and 53.7 and percentage of reduction 92%…

Microscope Essay Carolyn, 6C 20 November 2015 Microscopes How has the microscope helped our understanding of science and changed the world? The microscope has developed a huge understanding of science and really changed the world. Microscopes magnify tiny objects, which make them look a lot larger. Scientists use microscopes to see tiny objects that are too small to see with our eyes. These include cells, tiny living things, and grains of sand. A compound light microscope can give a…

The rabies virus has already survived for hundreds of years and is often fatal. The are 71 different species in this pathogen's family with 11 genera. The genus I identified is the lyssavirus from the family Rhabdovirdae. The species of the family Rhabdovirdae, I found on this farm in Montana, was rabies. Animals and humans can be a host to this virus. It is a zoonotic disease prevalent in wildlife, and the main animals involved vary between continents. In North America the main animals involved…

1) Two ampicillin resistant bacteria often present in salad; Aeromonas spp. Gram Negative, Bacillus Pseudomonas spp. Gram Negative, Bacillus Oxidase Positive Oxidase Positive Fermentative Oxidative The results found in table 2, match the specification for Aeromonas spp being gram…

It is well known that phosphorus is a major growth limiting plant nutrient for completion of plant life cycle. The exogenous application of P as chemical fertilizer has been found indispensable for the maximized crop yields but continuously increasing cost and non-availability of phosphatic fertilizer is a great barrier to farmers. It is comprehensively reported that most of the soils are sufficient in total P content but the major constraint is the availability of P to plants because it forms…
