Human bocavirus (HBoV) is a recognized human parvovirus associated with acute respiratory tract infection. However, HBoV has yet to be established as a causative agent of respiratory disease. In this study, the epidemiological and virological characteristics of HBoV infection were studied in children with acute respiratory tract infection in China. In… (More)
A simple and sensitive Reverse Transcription Loop-mediated Isothermal Amplification (RT-LAMP) method was established to provide a new alternative for clinical diagnosis of Avian influenza A H5N1 virus. The method employed a set of six specially designed primers that recognized eight distinct sequences of the target for amplification of nucleic acid under… (More)
Human rhinovirus C (HRV-C) is a newly identified genotype of HRV found in patients with respiratory tract infections (RTIs); however, its epidemiological profile and clinical characteristics are not well understood. In this study, Chinese children with RTIs were screened for HRV-C and their epidemiological and clinical characteristics were analyzed. From… (More)
A newly identified parvovirus, human bocavirus (HBoV), was found in 21 (8.3%) of 252 nasopharyngeal aspirates from hospitalized children with lower respiratory tract infection in Hunan Province, People's Republic of China. Viral loads were 10(4) to 10(10) copies/mL. Phylogenetic analysis of the VP1 gene showed a single genetic lineage of HBoV worldwide.
Human bocavirus (HBoV) and HBoV2, two human bocavirus species, were found in 18 and 10 of 235 nasopharyngeal aspirates, respectively, from children hospitalized with acute respiratory tract infection. Our results suggest that, like HBoV, HBoV2 is distributed worldwide and may be associated with respiratory and enteric diseases.
There are limited data on the prevalence and clinical and molecular characterization of human respiratory syncytial virus (HRSV) in children with acute respiratory tract infections (ARTIs) in China. From December 2006 to March 2009, 894 nasopharyngeal aspirates (NPAs) were collected from children under 14 years of age with ARTIs. Samples were screened for… (More)
UNLABELLED To investigate the epidemiological features and types of human adenoviruses (ADV) in children with acute respiratory tract infection in Nanjing area, China. Nasopharyngeal aspirates and nasopharyngeal swabs were collected from 644 outpatients or hospitalized pediatric patients with ARTI at the Children Hospital of Nanjing, Jiangsu Province,… (More)
Human adenovirus (HAdV) is an important agent causing respiratory tract infection in children. Information on the epidemiological and clinical features of HAdV is limited in children with acute respiratory tract infections (ARTIs) in China, especially those of a novel genotype, Ad55. In total, 1169 nasopharyngeal aspirates were collected from children… (More)
Recently identified interferon-epsilon (IFN-epsilon) belongs to type I interferons. IFN-epsilon is highly and constitutively expressed in the brain, but its biochemical and biological characteristics are poorly understood. In this study, full-length IFN-epsilon cDNA was cloned from human peripheral blood lymphocyte by RT-PCR, and was expressed in… (More)
OBJECTIVE To investigate newly identified polyomavirus WUV and WUV and KIPyV are associated with acute respiratory infections in China, tests were developed to detect WUV and KIPyV gene fragments from nasopharyngeal aspirates collected from children with ARI fron Nov. 2006 to Oct. 2007. METHODS A total of 318 clinical samples were tested for WUV and KIPyV… (More)
