After the activation of these immune mechanisms and a latent period of infection and body immune responses, then active immunity is developed. The host immunity is then geared up to act against the foreign pathogen/antigen. This means that immune responses are normally slow on the onset (primary...

One example of host-pathogen coevolution is seen in theevolution ofsickle cell anemiain humans, which is thought to have arisen as a result of resistance tomalaria. The sickle cell gene, which causes abnormalred blood cells, also confers some resistance to malaria infection. As a result,indivi...

Size distributions of rainfall droplets. The volume of gas in a petroleum reserve.Many more phenomenon can be modeled with the lognormal distribution, such as the length of latent periods of infectious disease or species abundance [1].Other...
Antigenic shift, therefore, refers to a rapid change in the antigenicity of a viral infection that occurs due to the hybridization of the genomes of two different varieties of the viral infection. Antigenic shift is linked to pandemics because hosts lack immunity to the new strain of the ...

Explain why many viruses that cause cancer establish a latent infection in their human host. There are examples of viruses which cause cancer by carrying an activated oncogene into a cell. However, no cancer-causing viruses have been found that carry tumor suppressor genes. Why is this? Expla...
