The Ebola Virus Kimberly A. Murphy SC246- Unit 7 Assignment January 6, 2015 Professor Robert Black The Ebola Virus The Ebola virus which was first discovered in 1976 near the Ebola River in Africa is a deadly and rare disease that is caused by an infection of one of any of the five known strains of the Ebola virus. The genus Ebolavirus belongs in the family Filoviridae, a group of several related viruses that form virions also known as filamentous infectious viral particles and encode their

component of plasma membranes. 10. The functional group -COOH has acidic properties and would release hydrogen ions in an aqueous (water) solution. 11. The peptidoglycan of the bacterial cell wall contains a carbohydrate matrix linked together by short chains of amino acids. 12. Nuclear pores apparently permit the passage of only proteins inward and outward, but RNA only outward. 13. Mitochondria and chloroplasts are the other organelles besides the nucleus that contain DNA. 14. The Golgi apparatus and

Applying Epidemiology Charles B. Moore HCA 415 Instructor: Quida Davis April 27, 2014 Applying Epidemiology A mother of a young child called the Vermont Department on February 5 to report the possibility of a foodborne disease outbreak after her child aged 5 years and two other children of her neighbor aged 7 and 10 years became ill with a lot of vomiting and diarrhea that took place within an interval of 12 hours. The child’s sickness became severe that the mother took her to a local hospital

The Ageing Process “How Our Bodies and Minds Change” Aging is a process that concerns us all. The increasing armamentarium provided by molecular biology and other techniques has allowed greater understanding of some of the processes involved. Numerous definitions of aging exist; an acceptable and commonly used definition is that aging is the total of all changes an organism undergoes from its conception to its death, including development, maturation and adulthood. There are many theories about

DNA Fingerprinting DNA fingerprinting is a test to identify and evaluate the genetic information-called DNA (deoxyribonucleic acid)-in a person's cells. It is called a "fingerprint" because it is very unlikely that any two people would have exactly the same DNA information, in the same way that it is very unlikely that any two people would have exactly the same physical fingerprint. The test is used to determine whether a family relationship exists between two people, to identify organisms causing

Concepts in community and public health Safaa Soueid Grand Canyon University: NRS-427V-0191 March 16,2014 Communicable disease is a disordered caused by bacteria, viruses, fungi or parasites. Many organisms live in our body, normally they are unable to cause harm, but under certain circumstances may cause diseases (Mayo Clinic, 2013). The mode of transmission may vary; some infectious diseases may be transmitted via contact from person to person, or caused by bites from insects or animals

Over the last several years, Carbapenem-resistant Enterobacteriaceae (CRE) has presented a more serious and diverse problem across the world. Although it was not a big concern in the United States until the early 1990s, CRE is becoming more dangerous as the days go by due to susceptibility (Gupta, Limbago, Patel, & Kallen, 2011). CRE is a group of multiple bacterium that is very difficult to treat due to the high resistance to several antibiotics, which has earned them the name “Killer bacteria”

Materials and methods Location of the experiments This study was performed at the Plant Pathology Department, Faculty of Agriculture, Cairo University, Giza, Egypt Isolation of the pathogens Lettuce plant (cv. Aviram) showing wilt symptoms were collected from different fields located at Giza, Qalubiya, and Behira governorates. The infected roots were washed several times with tap water, cut tissues with the discolored vascular system or cortex after removing and discarding the epidermis into small

Microscopic studies of the human body have found that microbial cells greatly outnumber somatic cells with National Institutes of Health estimating the figure to be around 90%; these either being bacterial, fungal or otherwise non-human. Even though DNA sequencing techniques have allowed scientists to analyse the structures components and functions of some of these normal microbiota, a large fraction of them still remain unstudied and so therefore we have not yet understood the full extent as to
