Sarah Burns Evolution of Plague Bacteria The Bubonic Plague otherwise known as the Black Death‚ has gotten most of its attention from medieval paintings‚ poetry‚ and journals of revulsion. The real horror‚ was the disturbing biological evidence of the bacteria that caused all the pandemics‚ known as Yersinia pestis. The pathogen got its name from the two investigators Yersin and Kitasato. In 1894‚ Yersin was known as the main investigator (ergo. Named after him)‚ he claimed that the mice/rats were

Scholastic Scope: The Language Arts Magazine January 2014 Edition‚ pages 5-9 Bacteria surround us every day. These little “bugs” are invisible to the eye and most do not harm us. Many are necessary for us to survive‚ like the bacteria in our stomachs and intestines that help us to digest food. But some bacteria are very dangerous to us. Addie Rereich became very sick in May 2011‚ when she was 11 years old. What started as something that her doctors and mother were not worried about turned into

Communicable Disease: Communicable diseases‚ also known as infectious diseases or transmissible diseases‚ are illnesses that result from the infection‚ presence and growth of pathogenic (capable of causing disease) biologic agents in an individual human or other animal host. Infections may range in severity from asymptomatic (without symptoms) to severe and fatal. The term infection does not have the same meaning as infectious disease because some infections do not cause illness in a host. Disease causing

Celiac disease affects approximately 1-2% of the general population1 and is a serious genetic autoimmune disease that attacks any gluten that enters the body and intern damages the villi and mucosa in the small intestine‚ which affects absorption of nutrients from food1‚2. This damage to the small intestine can lead to malnutrition1‚2. Gluten is a protein that is found in barley‚ wheat‚ oats and rye1‚2. Since gluten is in many foods‚ this disease will greatly affect people’s diets‚ and lead to changes

Zika virus can be contracted by being bitten by the mosquito Aedes aegypti. Puerto Rico being an island where is warm all year round makes the perfect breeding environment for this mosquito. At least 117 people have tested positive for the Zika virus in Puerto Rico and five of them are pregnant women. The Zika virus in Puerto Rico‚ how did it get there? Is the population in Puerto Rico able to fight this epidemic? How can the people in the island protect themselves from acquiring this virus? The

Choice "A" is the best answer. Cytomegalovirus (CMV) mononucleosis is the most common cause of heterophile-negative infectious mononucleosis-like infections. Primary CMV infection is defined as infection in an individual who has never had a CMV infection before. In primary CMV infection patients‚ the first antibody to appear is the CMV IgM. It can be found as early as four weeks after infection and can remain positive for up to 20 weeks. Other antibodies present in primary CMV infection patients

He was stationed in Kenya and Somaliland. Burkitt was ambitious to offer his help to Uganda at that time because it was both a thriving and peaceful country with much Christian activity. This appealed deeply to Burkitt’s religious views. After

microorganisms is vital in health and medicine. This capability is important for a variety of reasons‚ such as knowing the causative agent of disease‚ knowing if the microorganism obtains any beneficial properties and knowing the correct microorganism to use to create a successful antibiotic. Implementing the experimental methods learned thus far in the microbiology laboratory allowed an unknown bacterium to be identified as a result of this study. This study allows the student to exercise their ability

MOLECULAR DETECTION OF FUNGAL DISEASES INTRODUCTION With the rise of many new diseases caused due to viruses‚ bacteria and fungi; it is essential for the rapid detection of such diseases. The severity of such diseases can be reduced by its rapid detection carried out by different methods. The conventional methods may include the idea of just identifying the disease symptoms‚ identification of these pathogens in the laboratory by different morphological and biochemical tests‚ etc [1]. The conventional

The Ebola Virus A virus is an ultramicroscopic infectious organism that‚ having no independent metabolic activity‚ can replicate only within a cell of another host organism. A virus consists of a core of nucleic acid‚ either RNA or DNA‚ surrounded by a coating of antigenic protein and sometimes a lipid layer surrounds it as well. The virus provides the genetic code for replication‚ and the host cell provides the necessary energy and raw materials. There are more than 200 viruses that
