Virus News and Research RSS Feed - Virus News and Research

A virus is a microscopic infectious agent that can reproduce only inside a host cell. Viruses infect all types of organisms: from animals and plants, to bacteria and archaea. Since the initial discovery of tobacco mosaic virus by Martinus Beijerinck in 1898, more than 5,000 types of virus have been described in detail, although most types of virus remain undiscovered. Viruses are ubiquitous, as they are found in almost every ecosystem on Earth, and are the most abundant type of biological entity on the planet. The study of viruses is known as virology, and is a branch of microbiology.

Research sheds new light on the development of HPV-associated cancer

It's long been known that certain strains of human papillomavirus (HPV) cause cancer. Now, researchers at The Ohio State University have determined a new way that HPV might spark cancer development - by disrupting the human DNA sequence with repeating loops when the virus is inserted into host-cell DNA as it replicates.

Researchers uncover mechanism that may help explain severe forms of schistosomiasis

Researchers uncover mechanism that may help explain severe forms of schistosomiasis

​Researchers at the Sackler School of Graduate Biomedical Sciences at Tufts and Tufts University School of Medicine (TUSM) have uncovered a mechanism that may help explain the severe forms of schistosomiasis, or snail fever, which is caused by schistosome worms and is one of the most prevalent parasitic diseases in the world. The study in mice, published online in The Journal of Immunology, may also offer targets for intervention and amelioration of the disease. [More]
