BACKGROUND: Mycoplasma gallisepticum (MG) and Mycoplasma synoviae (MS) are the most important and pathogenic mycoplasma in chicken production. The tendency of avian mycoplasma for interaction with other pathogen is well-known. Interaction within several disease-producing factors in respiratory tract exacerbate the disease and known as multicausal respiratory disease. OBJECTIVES: In recent years...

Infectious Laryngotrachitis (ILT) is an acute respiratory disease with high morbidity and low mortality in poultry. ILT is caused by Gallid herpesvirus 1 (GaHV-1), a member of the Iltovirus genus and family Herpesviridae. It resulted in notable economic losses due to decreasing the growth rates, egg production, and increasing the mortality in commercial poultry, especially layer flocks, and usu...

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 ...

on june 2005, a respiratory disease was observed in the chickens of a large broiler farm in kermanshahprovince, west of iran. relatively severe respiratory signs started with sneezing at 27 days of age. thedisease lasted up to the end of fattening period and accompanied by increased mortality (13.6%). at postmortemexamination, tracheitis, airsacculitis and pneumonia were obvious. serologic exam...

BACKGROUND The etiology of transfusion-related acute lung injury (TRALI) is often referred to as a "two-hit model," the first hit being patient predisposition and the second being a transfusion. This model lumps all patient-related risk factors together and thereby may hamper identification of individual, potentially preventable or modifiable risk factors. STUDY DESIGN AND METHODS Like any di...

background: respiratory virus infections in children are a leading cause of morbidity and mortality worldwide. methods : a total of 897 clinical specimens were collected from february 2007 to january 2008 and transported to the na­tional influenza center. two hundred and two samples belonged to children under the age of six from 897 specimens, de­scribed above, were selected. then they were tes...

Respiratory muscle dysfunction, particularly of the diaphragm, may play a key role in the pathophysiological mechanisms that lead to difficulty in weaning patients from mechanical ventilation. The limited mobility of critically ill patients, and of the diaphragm in particular when prolonged mechanical ventilation support is required, promotes the early onset of respiratory muscle dysfunction, b...
