Arenavirus News and Research

RSS

Arenaviruses are enveloped viruses (about 120 nm diameter) with a bi-segmented negative strand RNA genome. The typical image in electronic microscopy showing grainy ribosomal particles (“arena” in latin) inside the virions gave the name to this family of viruses.

Novel virus could be source of severe respiratory disease in ball pythons

Researchers have identified a novel virus that could be the source of a severe, sometimes fatal respiratory disease that has been observed in captive ball pythons since the 1990s. The work is published this week in mBio-, the online open-access journal of the American Society for Microbiology.

Researchers create biyouyanagin compound library

Using chemical compounds found in a Japanese plant as a lead and the clever application of ultraviolet light, a Scripps Research Institute team has created a unique library of dozens of synthetic compounds to test for biomedical potential. Already, one of the compounds has shown great promise in inhibiting replication of HIV particles and fighting inflammation.

Update on suspected Acute Haemorrhagic Fever in Republic of the Congo

Blood samples taken from one of the suspected cases in Sangha Region, Republic of Congo, tested negative for several viral haemorrhagic fevers (Ebola, Marburg, CCHF, Arenavirus).

Novel interventions for New World hemorrhagic fevers needed

New World hemorrhagic fevers are emerging infectious diseases found in South America that can cause terrible, Ebola-like symptoms. Current treatments are expensive and only partially effective.

Discovery of new arenavirus associated with hemorrhagic fever – first identified in nearly four decades

Scientists at Columbia University's Mailman School of Public Health, the South African National Institute for Communicable Diseases of National Health Laboratory Service (NICD-NHLS), the U.S. Centers for Disease Control and Prevention, and Roche's 454 Life Sciences Corporation have discovered the new virus responsible for a highly fatal hemorrhagic fever outbreak in Zambia and South Africa in late 2008.

Chapare virus, a newly discovered arenavirus

A team of Bolivian health authorities, U.S. Navy health experts based in Lima, Peru, and the U.S. Centers for Disease Control and Prevention has characterized "Chapare arenavirus," a previously unrecognized arenavirus, discovered in serum samples from a patient in rural Bolivia who eventually died of the infection.

Organ-recipients' deaths prompt call for suppliers of pet rodents to screen for lymphocytic choriomeningitis virus

A case involving seven transplant recipients killed by a rodent-borne virus that they apparently acquired from donated and infected human organs has prompted a recommendation that regulatory authorities require suppliers of pet rodents to screen their colonies for the virus.
