Other STDs are not curable, but can be treated. To make sure your treatment works, don't share your medicine with anyone, and avoid having sex again until you and your sex partner s have each completed treatment. If you are diagnosed with an STD, it's important to tell your partners to get checked so that you don't get re-infected. The free poliovirus-infected cell cultures did not yield more virus than the cell cultures infected with vesicles. NIH deputy director for intramural research Dr.

Michael Gottesman chats with Altan-Bonnet. She thinks this is because when one or two viruses infect a cell, replication is not that efficient: it takes time for an RNA virus to replicate, and if a virus has a mutation that affects its ability to replicate, the process stops. Remarkably, she has found that these vesicles also can transmit infection among organisms. Clinical trials for intravenous administration of phages are ongoing.

Viral infections at a young age are important to ensure the proper development of our immune systems. In addition, the immune system is continuously stimulated by systemic viruses at low levels sufficient to develop resistance to other infections.

For example, latent non-symptomatic herpes viruses can help human natural killer cells a specific type of white blood cell identify cancer cells and cells infected by other pathogenic viruses.

They arm the natural killer cells with antigens a foreign substance that can cause an immune response in the body that will enable them to identify tumour cells. This is both a survival tactic by the viruses to last longer within their host, and to get rid of competitive viruses to prevent them from damaging the host. In the future, modified versions of viruses like these could potentially be used to target cancer cells. The virus slows disease progression by blocking the host receptors required for viral entry into the cell, and promotes the release of virus-detecting interferons and cytokines proteins produced by white blood cells that activate inflammation and removal of infected cells or pathogens.

In another example, noroviruses were shown to protect the gut of mice when they were given antibiotics. Note: Content may be edited for style and length. Science News.
