Marburg virus

(Nazarko, 2013). People develop chickenpox when they first exposure to herpes virus in childhood. When they recover from chickenpox, the virus remains in the spinal nerves in a dormant form. People with healthy immune systems keep the virus dormant with no symptoms of shingles. When people are in immune depressive status or when people are aging, they have increased risk to develop shingles due to reactive the herpes virus in the body. According to Conceicao and Shostak (2015), the typically…

Anyone who carries the guinea worm will begin to experience symptoms one year after they originally become infected. 90% for the worms appear on the legs and feet, but can occur anywhere through out the body. (MedicineNet) One of the first symptoms a person will experience is pain. The worm causes an abnormal growth also known as a skin lesion. These skin lesions lead to bacterial infections causing the infected person to experience immense pain through out the site of infection. If the…

Mumps is a contagious disease that is caused by a virus. It is transmitted from person to person through saliva, nasal secretions, and close personal contact. Mumps primarily affect the parotid glands or the salivary glands. The hallmark symptom of the mumps is swollen and tender salivary glands under the ears on one or both sides. Other symptoms include fever, headache, muscle aches, tiredness, and loss of appetite. Symptoms typically appear 16-18 days after the infection, but this period can…

Human genetic engineering, the manipulation of genes in an organism intended to better an organism, is quickly becoming a controversial topic. As technology advances and more tests are conducted, society becomes a step closer to creating the “perfect” baby. Many possibilities have become a reality, and questions such as, “How would the practice of human genetic engineering influence diversity in society?” have been raised. Many factors and situations must be taken into consideration to answer…

Epstein-Barr Virus is part of the herpesvirus family and was the first virus discovered to cause a human cancer. The virus has two stages of its life, the latent phase, which allows the virus to lie dormant within a cell and the host. The other stage is the lytic phase in which the virus reproduces and allows the virus to spread among cells. Haloperidol (HPD) aids in the initiation of the lytic cycle. The Haloperidol will be administered at varying concentrations and exposure times. Using…

In the 1920s, A British researchers named Frederick Griffith studied bacterial pneumonia to find a vaccine for it. The specific bacteria was Streptococcus pneumoniae. Using streaking on a cultured Petri dish, the batterie was seperated into two strains, or colonies. The R-Strain was rough, and when injector into mice, it did not cause pneumonia, but the S-strain was smooth and slimy, and caused lethal pneumonia when injected. When the S-Strain was killed by heat, it did not cause sickness, but…

they are present and depend on another living organism/host. 8. (4 points) Discuss the differences between enveloped animal virus and naked animal virus in their ways of viral multiplication. Enveloped animal virus is composed of lipids, proteins, and carbohydrates (some have spikes arounds them). Naked animal virus is composed of capsomeres, but doesn’t contain an…

A virus is a small infectious agent. There are different types of viruses. Viruses are all over the world and can be caused by many things and substances. Viruses are nonliving, it contains genetic information, has to survive (DNA/RNA) in a host, and can multiply from 1 virus to 1,000. Viruses have 3 components. Capsid surrounds DNA, Tail sheath-connected to capsid, and tail-fibers-connected to the sheath. The virus DNA travels down the tail sheath through the membrane. The virus tricks the cell…

What is a Virus? Virus - A virus is a tiny organism that can reproduce inside the cells of an organism. Most viruses are microscopic they are only observable through an optical microscope. Viruses can infect all types of organisms ranging from plant to animals as well as bacteria and other archaea. There are around 5000 different types of viruses described at the current time, however, it is thought that there are millions different viruses of distinct types. Viruses are seen in every…

Mitochondria was first discovered in 1856 by Swiss anatomist Van Kölliker. Dr. Kölliker while he was conducting a study on muscle tissue (Giezen, Page 1). He found these “sacrosomes” which would later become known as mitochondria. When scientist first started discovering mitochondria they were extremely fascinated with all of the various structures of the mitochondria (Giezen, Page 1). Early scientist posted numerous theories of the origin of mitochondria. One of these theories was that…
