Background: Acute respiratory tract infections, both bacterial and viral, cause 4.5 million childhood deaths worldwide, most of which occur in developing countries. Parainfluenza viruses, of the paramyxoviridae family, are among the common causes of acute respiratory infections, giving rise to 30% of respiratory infections in children before school age. The four parainfluenza viruses that cause...
Background and purpose: The acute lower respiratory tract infective agents in children are different. The rate of their role in causing infection differs with the age of patients, season, geographical areas and diagnostic methods. The aim of this study is to determine the rate of the role of respiratory syncytial and influenza viruses in Mazandaranian children infected with acute lower res...
Background: Respiratory virus infections represent a major public health problem because of their worldwide occurrence, ease of spread in the community and considerable morbidity and mortality. They are one of the most common reasons for hospitalization of children under the age of six. In some cases, infection with two different viruses increase the severity of disease which lead to the h...
Avian Influenza (AI) is a viral respiratory disease of domestic and wild birds. In the diagnostic laboratory, it is essential to have methods for rapid detection of avian respiratory viruses. Cloacal swabs collected from chickens experimentally infected with H9 subtype AI virus, used in a reverse transcription-polymerase chain reaction (RT-PCR) assay for detection of AI. In infected animals, ...

Respiratory disorders are major concern for dairy cattle industry. Viruses and bacteria in combinationwith stress play a key role in triggering acute respiratory infections. The most important viral agents arebovine viral diarrhoea virus (BVDV), bovine herpes virus type 1 (BHV-1), bovine respiratory syncytial virus(BRSV), parainfluenza virus type 3 (PIV-3) and bovine adenovirus (BAV). This cros...
Corona viruses are large group of viruses that can cause sickness ranging from normal flu to severe respiratory diseases. The new novel corona virus (nCOV-19) or COVID-19 is a new kind of pandemic virus that did not identified before in humans. Global nations have heightened their surveillance in the quick diagnosis of potential cases across the COVID-19. After it had originated in China more c...
BACKGROUND: Newcastle disease virus (NDV) is one of the most principal contagious diseases with a significant role in multifactorial respiratory diseases in the poultry industry. OBJECTIVES: This study aims to evaluate and detect NDVs in multicausal respiratory diseases. METHODS: A total of 180 tracheal swabs were collected from 20 ...
