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: Moraxella catarrhalis is Gram negative diplococci which is a member of Neisseriacae. It was considered as a harmless commensal of the upper respiratory tract. Since 1990 its pathogenecity was established and known as a common cause of respiratory infection, particularly otitis media, sinusitis and lower respiratory tract. The aim of this research was to determine the prevalence and ...
Introduction: Gastrointestinal tract may act as a transmission route of infection apart from the respiratory tract in the spread of viral diseases. Covid pneumoniae 19 is a highly contagious infectious disease. There is growing evidence that patients with Covid 19 can develop gastrointestinal symptoms. The present study was performed to investigate the possibility of Covid 19 infection through ...
Respiratory syncytial virus (RSV) causes recurrent upper and lower Respiratory tract infections (especially pneumonia and bronchiolitis). Detection of the infection with respect to its morbidity seems to be a nessecity. In this research nasopharyngeal secretions of 145 patients with respiratory symptoms from Imam Khomeini, Markaz Tebbi and Baharami hospitals were analyzed with direct immunofluo...
Background and Aims: The role of BK and JC polyomaviruses (BKV and JCV) in the causation of respiratory disease and the natural route of transmission has not well been established. The aim of study was to determine the prevalence of BK and JC viruses in 280 respiratory samples and evaluate their contribution to respiratory disease. Materials and Methods: PCR was used to screen specimens for BK...
AIM to have the picture of infectious disease pattern and serum albumin level in elderly people with respiratory tract infection hospitalized at the Internal Medicine Ward, Dr. Moewardi Hospital Surakarta. METHODS descriptive-retrospective study. Sample was taken from the medical records of patients hospitalized at the Internal Medicine Ward DR. Moewardi Hospital from January to December 2004...
Toll like receptors (TLRs) with a myeloid differentiation antigen (CD14) recognize and bind various structures from invading microbes and then trigger cell activation. They initiate a variety of effectors' functions, including cytokine secretion, proliferation, co-stimulation or phagocyte maturation. The aim of this study was to evaluate Toll-like receptor 4 (TLR4) and CD14 expression in childr...
Upper respiratory tract infection (URI) is a general term for a heterogeneous group of illnesses caused by numerous etiologic agents that affect the mucosal lining of the upper respiratory tract, including the middle-ear cavity and paranasal sinuses. URIs are primarily caused by viruses, rhinoviruses being the most common etiological agents. Respiratory viruses transmit easily via direct contac...
Background and purpose: Since adenoviruses could be one of the causes of health problems in children and due to lack of epidemiologic evidences, always will be misdiagnosed with bacterial infections and treated with antibiotics. This study was planned and performed to determine the frequency of adenoviruses in lower respiratory tract infections in children under 14 years referring to 6 Tehran...
