Outbreak The virologists determined the identity of the virus causing the disease by taking blood samples from the people who were sick or who were getting sick‚ the n they put them under the microscope and studied them. They tracked the epidemic down by following where people were getting sick; the virologists finally followed the virus back to the ship that was carrying all the animals and the monkey. They conquered the virus by taking the serum from the host after they caught it and injecting

Symptoms And Treatments For Genital Herpes Genital Herpes is a sexually transmitted disease‚ caused by two kinds of simplex viruses‚ such as type-1 virus and type-2 virus. Any sexually active man or woman can get this disease. It will spread when people engage in oral‚ anal‚ or vaginal sex. Most people who have genital herpes have no‚ or extremely mild symptoms. Mild symptoms cannot be noticed or they may be mistaken for another skin disorder‚ such as ingrown hair or a pimple. Due to this‚ most people

RNA) encased in a protein capsid‚ a virus is too small to be seen by standard light microscopy; indeed‚ most are less than one hundredth the size of a bacterium. Specific proteins on the viral capsid attach to receptors on the host cell; this attachment process is essential to viral infectivity and explains why viruses may only infect the cells of certain species or may only infect certain cells or tissues within a given host species. While the infecting virus triggers an immune response in the

11. What conditions are treated with metronidiazole? What is the mode of action of this drug? Metronidazole or commonly known as Flagyl is a widely used amoebicide used to treat mild to severe intestinal infections and hepatic disease caused by Entamoeba histolytica. It works by invading essential metabolic enzymes of the pathogens and is also used for infections caused by Giardia lamblia and Trichomonas vaginalis. 12.

***Due March 31 before class! *** Case Study “Influenza” The second case study of the semester is centered around the topic of influenza. There are two areas of reading/research for this case study. The first (homework #1) pertains to a pandemic influenza that affected people worldwide in 1918-1919. The second (homework #2) involves research into more current strains of influenza that have been found. Please type a response/explanation to the seven questions listed below. You may put both homework

Varicella Virus Whether something serious as cancer or the common cold‚ each of these things started with a virus. Viruses come in many different forms. There are about 1 million different viruses and they are everywhere. A virus is a microscopic infectious agent that can replicate only inside the living cells of organisms. One of such is a virus commonly known as the Chicken Pox. The Chicken Pox is caused by a virus called ‘Varicella’‚ which is very contagious. Symptoms of this virus include a

additional outside research to answer the questions: 1 Discuss the two methods of viral replication. The two methods of viral replication are done in animal viruses. The first method deals with DNA viruses and the second is RNA viruses. In the DNA virus‚ the viral DNA enters the nucleus of the host cell. Than it is transcribed into mRNA and leaves the nucleus into the cytoplasm. The early mRNA then translates into early viral proteins. The early viral proteins deal with the replication of viral DNA

manufacturing When first created‚ GM foods were to improve crop protection for easier growth and shipping. Now they are used to enhance taste and visual appearance. Why do we use them? Virus resistance is achieved through the introduction of a gene from certain viruses which cause disease in plants. Virus resistance makes plants less susceptible to diseases caused by such viruses‚ resulting in larger manufacturing. Difference between “natural” and “ORGANIC” In the food industry today
