فيروسات المايكوبلازما و دورها في امراضية المايكوبلازما في الدواجن

الملخص EN

Mycoplasma viruses return to family Plasmaviridae , and they are small organisms which infect the mycoplasma cells and increase their virulence for containing specialized code in their genetic material.

These viruses could characterize by their ability to form plaques on mycoplasma cells or on the host cell that had been mycoplasma isolated from it.

Many viruses had been discovered over 50 years ago.

If mycoplasma viruses term which is known now , change to include more other known viruses like Newcastle disease viruses (NDV) , infectious laryngeo trachitis viruses (ILTV) and infectious bronchitis viruses (IBV) and play a role by increase mycoplasma virulence in some way then show their signs in sever cases.

These viruses activated and developed inside the mycoplasma cell to increase its virulence which specifically infect mycoplasma cells or they could infect a strain not another one of mycoplasma .

Scientists mentioned that a specific mycoplasma cells may contain two kinds of mycoplasma viruses which they have microparacitical activity.

Mycoplasma virulence which infect poultry fields.

Later a lot of scientists had called these mycoplasma viruses in different callers and isolated in different diagnostic methods , since it had been discovered.

Its obviously that all scientists agreed that mycoplasma cell needs more complicated conditions than any other bacteria when cultured.

had been investigated mycoplasma viruses between 1967-1968.

All studies now are going to explain the diagnosis of mycoplasma viruses , and how they could infect mycoplasma cells , and they increase their virulence of mycoplasma cells which may infecting by another species of viruses like Newcastle disease virus (NDV) , Infectious bronchitis disease virus (IBV) , Infectious laryangeo – trachitis disease virus (ILTV) , Marek's disease viruses (MDV) and avian infectious bursa disease viruses (IBDV) .

Interfere between these viruses above with mycoplasma cells or any live cells may gives us new mycoplasma viruses generations , which it could be dangerous not for poultry only , but also to human and all other animals .

Just like what happened in the world today like disease which infect human , when we had thought destroyed them and they disappeared but later will had backed stronger and that fit all viruses which infect human and animal.

So our article try to explain how these viruses increase mycoplasma virulence , and if we could decrease or preventing such interfere between mycoplasma and viruses which increase their virulence in result.
