تعیین فراوانی عفونت ویروسی پاراآنفلوآنزا به روش ایمونوفلوئورسانس در عفونت‌های حاد تنفسی

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...

Studies of Parainfluenza Viruses

Serologic cross reactions have been demonstrated between members of the parainfluenza subgroup of myxoviruses.7'-Similar antigenic relationships have also been noted between mumps virus and each of the four parainfluenza virus serotyes" and between mumps and Newcastle disease virus.7'8 Furthermore, the DA virus, § a myxovirus recently isolated from human blood, which is serologically indistingu...

The Frequency Distribution of Parainfluenza, Adeno and Respiratory Syncytial Virus Infections in Children below 2 Years Old with Bronchiolititis, by Multiplex Polymerase Chain Reaction Method, Afzalipoor Hospital, Kerman, 2006

Background & Aims: Acute respiratory infections are common cause of mortality during childhood. This study was designed to determine the incidence of adenovirus, parainfluenza virus and respiratory syncytial virus in respiratory infections by Multiplex PCR method. Methods: This study included 168 children under 2 years of age with clinical diagnosis of bronchiolitis. Nasopharyngeal specimens we...

تعیین میزان شیوع ویروس های پارا آنفلوآنزا و آدنوویروس در عفونت های مجاری تنفسی تحتانی بیماران بستری شده مازندران طی سال های 81-1380

Rate of their role is based on the age of patients, season, geographical areas and the used diagnostic methods. Âim of this study is to determine rate of infections causecl by these viruses in the patients admitted for lower respiratory tract infection Materials and methods: Çh...

Preliminary survey for antibodies against respiratory viruses among slaughter camels (Camelus dromedarius) in north-eastern Nigeria

Antibody prevalence against respiratory viruses was noted, as follows: adenovirus (1.3%), influenza A (0.6%), influenza B (12.7%), parainfluenza-1 (22.3%), parainfluenza-2 (2.5%), parainfluenza-3 (18.5%) and respiratory syncytial virus (0.6%). The difference in antibody prevalence between the different virus antigens was statistically significant. High antibody rates to influenza B, parainfluen...
