Viruses are microscopic particles that are present in animals, plants, and other living organisms. They can sometimes cause diseases, such as the flu and COVID-19. Viruses are biological entities that ...

The immunogenicity of monkey kidney culture and chick embryo-propagated lines of influenza A1/GL/1134/53, A2/NO/1/57 and B/GL/1760/54 viruses was compared in rabbits and roosters. Antibody response to ...

For a long time, researchers contested the presence of microscopic pathogens suspected of causing various diseases in plants and animals. The invention of the electron microscope in 1933 made them ...

Current HIV-1 therapies have been proven to be highly effective in slowing the progression of the virus in the body with only minimal side effects. The daily antiretroviral therapy (ART) uses a ...

Researchers have developed a model that predicts which of the viruses that can jump from animals to people can also be transmitted from person to person -- and are therefore possible sources of human ...

With its many variations, its ability to mutate, evade population immunity, and spread throughout the population, and its potential to cause serious illness and even death, the influenza viruses are ...
