WebIntroduction. Human immunodeficiency virus (HIV) infection is a major public health challenge in Europe. Nearly 29,381 new diagnoses of HIV are reported yearly for European countries and the European Economic Area member states, with a rate of 5.8 diagnoses per 100,000 inhabitants. 1 In Italy, an incidence of 6.5 new diagnoses of HIV per 100,000 … WebWhile the immune system protects us from many pathogens, the inflammation that occurs as part of the immune response can also damage our own tissues and impair the … The H5N1 virus is a particularly lethal strain of influenza. Currently, it can infect humans, but it is not contagious between humans. Still, over 600 people worldwide are known to have died from animal-transmitted H5N1 virus, so the transmissibility of the virus is of major concern to scientists. See more Serial passage is the process of growing bacteria or a virus in iterations. For instance, a virus may be grown in one environment, and then a portion of that virus population can be removed and put into a new environment. This … See more The technique of serial passage has been around since the 1800s. In particular, Louis Pasteur's work with the rabies vaccine in the late 1800s exemplifies this method. Pasteur created … See more Researchers have conducted many experiments using serial passage. Some of the experimental uses for serial passage include changing the virulence of a virus, to study the adaptive evolution or potential evolution of zoonotic diseases to new hosts, and … See more Serial passage can either be performed in vitro or in vivo. In the in vitro method, a virus or a strain of bacteria will be isolated and allowed to grow for a certain time. After the sample has grown for that time, part of it will be transferred to a new environment and … See more One way to attenuate a virus to a host is by passing the virus in a different species.
