Ambitious, creative, and remarkable are the words that pop into my head when I hear the name, “Louis Pasteur”. Pasteur saved many lives in the era of the 1880’s. Pasteur also formulated vaccinations, created the Bacteria and Germ Theory, and investigated the case of silkworms. During Pasteur’s early time, he was born in Dole, France on December 27, 1822. Not being able to grow up with a silver spoon in Pasteur’s mouth, he became fascinated in the history behind science, and biology. Later on in Pasteur’s

Mike Mosko English 2 December 16th You’re overreacting, and It’s Not Helping. The coming of Ebola and its subsequent global spread has becoming impossible to ignore. In just over 8 months, the virus has infected a confirmed amount of almost 18,000 people worldwide, with over 6,000 of those cases resulting in death (CDC). Coinciding with the sudden appearance of cases emerging within the United States, the country is experiencing its most widespread health scare since the introduction of AIDS in the

Ebola is a virus that is often fatal without proper medical attention or if left untreated. There are three strains of Ebola, Bundibugyo, Zaire, and Sudan. Based on the PBS Frontline video entitled Outbreak, the disease was contracted by bats that the people of the Meliandou Village of Guinea in West Africa ate. Ebola is transmitted to humans that are in close contact with blood, organs, and any other bodily fluids from infected animals such as apes, bats, and porcupines. It is spread through direct

“Streptococcus Group A (GAS) is also called Streptococcus Pyogenes. This is a gram-positive coccus pathogen that causes a large variety of diseases” (Fieber & Kovarik 2014). Most GAS infections are mild such as Strep throat. Strep A is one of the most common pathogens that occur in humans. “Strep Throat is most common in children ages 5-15,although anyone can get it” (Strep Throat Medline Plus, n.d). Most of Streptococcus Group A can cause pharyngitis, Scarlet fever (red rash on the body), rheumatic

This report discusses two lab experiments on studying mixtures. The first lab was called Investigating Mixtures. The objective of that lab was to observe that not all liquids behave the same way when mixed with other liquids. We had to determine what would happen when you put vegetable oil into water. My hypothesis was when the vegetable oil is mixed with the water the oil will stay on top of the water. The second lab was called Mixed Substances. The objective for the lab was to see how properties

The -DNA plate and -DNA/+amp were control plates, no colonies were supposed to grow on these plates because of the -DNA, which occurred. The +DNA/+amp and +DNA/+amp/+IPTG plate were the experiment plates since it had +DNA instead of -DNA. Additionally, the cells on these two plates would transform and the plate would form colonies since they were the experiment plates. The purpose of incubating the cells in ice, then 42oC ice water, then back to ice was because to transform the cells and take in

Based on the results of my unknown A, I concluded that the bacteria was Escherichia Coli. After I had collected the results and compared them with my dichotomous key, I was convinced that Escherichia coli was the only organism with a bacillus morphology gram negative that was able to survive under this conditions. The result for the lactose fermentation clarified that the bacteria carrie the enzyme lactase in the DNA, therefore can ferment lactose and produce acid and gasses. This type of bacteria

Ebola is a rare and deadly disease caused by infection with symptoms such as fever and severe internal bleeding which can lead to organ shutdown. People can be exposed to the virus by direct contact of blood or secretions from the body. The Ebola virus came from several African countries. An “ Ebola” outbreak happened in Boston, December of 2014. Lee Gehrke an MIT professor had been working on a test for 2 years prior to the outbreak in MA. to determine which virus is Ebola or another virus so

Triple Sugar-Iron Agar The triple sugar-iron agar test or TSIA for short, is used to distinguish between the different types of Gram-negative bacilli, who can ferment glucose and produce a positive acid reaction. These bacteria are known as Enterobacteriaceae (Cappuccino and Sherman 2014f). This test tests for the presence of acid because of glucose fermentation, and the presence or lack thereof, of hydrogen sulfide. Like the carbohydrate fermentation test, the TSIA test medium contains lactose

a) Infectivity – the pathogen ability to survive, and multiply (infects) in a host cell b) Invasiveness – the ability to degrade and migrate through the extracellular matrix and invade the host cells. c) Virulence – the ability of the pathogen to defeat the host defenses which is to increase the severity and also the longevity of the symptoms d) Pathogenicity – the capacity to bring the disease situation. Pathogenicity is the sum of the effects of the destruction and obtrusiveness e) Host
