What is a pathogenic virus

Viruses can cause a wide range of illnesses, both short-term as well as long-term. They can affect your respiratory systems, gastrointestinal systems, reproductive systems, and even the brain and liver. Some examples of common diseases caused by viruses are:. Bacteria are single-celled microorganisms that live almost everywhere. Bacteria can be beneficial as well as harmful. Beneficial bacteria can be found in dairy products like milk and yogurt.

We also carry bacteria in our gut which help digest food and destroy disease-causing organisms. Harmful bacteria produce toxins which could make you fall ill. Bacteria can cause infections like tuberculosis, strep throat, and urinary tract infections. Common examples of harmful bacteria are:. The best way to prevent infections is to stop the spreading of pathogens.

This would include disinfecting areas regularly. Disinfecting eliminates microbial life such as bacteria and virus. At Service Master Elite Cleaning Services, we are committed to ensuring the good health and safety of all our patrons. The cytopathic effect can develop when the virus alters the metabolism of the cell and prevents it from producing essential cellular components.

Alternatively, the virus may induce cells to cling together in a large mass called a syncytium. In some cases, the virus causes the cell's lysosomes to release enzymes which then destroy the cell. Previous Enzymes and Toxins. In some circumstances, a virus fails to reproduce itself and, instead, enters a latent state called lysogeny in the case of bacteriophages , from which there is the potential for reactivation at a later time.

A possible consequence of the presence of viral genome in a latent state is a new genotype for the cell. Some determinants of bacterial virulence and some malignancies of animal cells are examples of the genetic effects of latent viruses.

Apparently, vertebrates have had to coexist with viruses for a long time because they have evolved the special nonspecific interferon system, which operates in conjunction with the highly specific immune system to combat virus infections.

Some viruses, instead of reproducing, enter into a latent state from which they can later be reactivated. Two classes of infectious agents exist that are structurally simpler than viruses, namely, viroids and prions. Viroids are infectious circular RNA molecules that lack protein shells; they are responsible for Your MyAccess profile is currently affiliated with '[InstitutionA]' and is in the process of switching affiliations to '[InstitutionB]'.
