Even single cell organisms like bacteria can reproduce independently on surfaces outside the body, but viruses can only survive for a while outside host cells.

The other major complication of HTLV-1 is a rare type of cancer: adult T-cell leukemia/lymphoma (ATL). It’s estimated that ...

Most influenza viruses enter human or animal cells through specific pathways on the cells' surface. Researchers have now discovered that certain human flu viruses and avian flu viruses can also ...

Although outbreaks of Ebola virus are rare, the disease is severe and often fatal, with few treatment options. Rather than ...

One occurs when two viruses use the same molecule to gain entry into host cells. If virus A gets there first, and grabs on to all those molecular doorknobs, then virus B will have no opportunity ...

Whilst the ultimate outcome of the lytic cycle is production of new phage progeny and death of the host bacterial cell, this is a multistep process involving precise coordination of gene transcription ...

Viruses replicate by inserting themselves into host cells and hijacking their replication tools. If this happens in a germline cell (eggs and sperm), the viral code can be passed on to the next ...

These viruses have resided in the bodies of bats for millennia, but are pre-programmed with the ability to infect a humans; the key that unlocks some of our cells, where they can replicate.

Zika virus hijacks a key protein implicated in brain development for its own replication. Researchers led by Associate Professor Priya Shah at the University of California, Davis (CA, USA), have ...
