Differential Diagnosis of Respiratory Viruses by Using Real Time Rt-pcr Methodology
نویسندگان
چکیده
The emergence of new respiratory viruses including: the Severe Acute Respiratory Syndrome; the coronavirus in 2003 (SARS-CoV); influenza A(H1N1)pdm09, in the human population in the past ten years; the emergence of a new coronavirus identified in a patient presenting severe acute respiratory syndrome who travelled to Saudi Arabia (June, 2012), denominated as Middle East Respiratory Syndrome (MERS-CoV); and laboratory confirmation of three human infections with an avian influenza A(H7N9) virus not previously reported in humans on March 29, 2013, has encouraged scientists to develop diagnostic tests to identify these viruses. The Adolfo Lutz, a Public Health Institute, has been improving its methodology tools in order to provide a timely answer to public health authorities facing acute respiratory disease outbreaks.

Background: Currently, with increasing risk of influenza A virus epidemics, a lot of studies have been performed. Oseltamivir or Tamiflu (the neuraminidase (NA) inhibitor) is one of the effective drugs for preventing and treatment of these viruses. The H274Y mutation is from the most important drug resistant factors in influenza A viruses. The aim of this study was detection of Oseltamivir...

Avian influenza viruses (AIV) affect a wide range of birds and mammals, cause severe economic damage to the poultry industry, and pose a serious threat to humans. Highly pathogenic avian influenza viruses (HPAI) H5N1 were first identified in Southeast Asia in 1996 and spread to four continents over the following years. The viruses have caused high mortality in chickens and various bird species ...
