West Nile virus

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…

The rash caused by shingles is characterized by itchiness, but pain is an even more frustrating issue. On each side of your body, there are pathways for nerve roots that supply sensation to the skin. When the varicella-zoster virus, the same one that causes chickenpox, becomes reactivated, red blotchy patches on one side of your body or face, cluster along nerve pathways. It is common for an infected individual to complain of shooting pain in the region where the rash appears. Shingles…

with the cell nature as well as the varied virus character demands pointing to the viruses coming first. To a degree, the theories that designate this phenomenon have contended on the dissimilar nature of viruses, as a crucial factor that illustrates the viruses coming first (Woese, 1987). In the biosphere of microbes, whereas viruses are regarded as minuscule in size, the Pithovirus is known to be the opposite. It has been recorded as the largest virus that has ever been revealed and…

such as herpes varicella-zoster virus,simplex viruses,human herpesvirus,Epstein-Barr virus, Kaposi's sarcoma-associated herpesvirus and human cytomegalovirus. But there are over 130 herpesviruses affecting animals as well such as birds, fish, reptiles as well as much more.According to the CDC in the United States, about 1 out of every 6 people aged 14 to 49 years have genital herpes.The popularity of HSV-2 was nearly twice as high among women and was…

Seasonal influenza is a common cause of lower respiratory tract infections that annually effect a large portion of the population. These infections typically range from mild to moderate in severity, however life-threatening cases can occur. Frequently, complications associated with influenza infections are due to secondary bacterial pneumonia predominately caused by Streptococcus pneumoniae or Staphylococcus aureus (Rynda-Apple, Robinson, & Alcorn, 2015). Many efforts to resolve this pathology…
