| respiratory syncytial virus infection in young children hospitalized with respiratory illness in riyadh. | the occurrence of respiratory syncytial virus (rsv) infection among young children hospitalized with lower respiratory tract illness, at king khalid university hospital in riyadh, was examined during the autumn-winter season between september 1991 and february 1992. sixty-nine cases were diagnosed by immunofluorescent antibody staining of viral antigen in nasopharyngeal aspirates from 127 children, constituting 54 per cent of these patients. virus culture was attempted only in a few cases, yield ... | 1993 | 8133556 |
| respiratory viruses in children attending a major referral centre in saudi arabia. | viral respiratory infections are common causes of illness in infants and children. examination of clinical specimens submitted for diagnosis during a 3-year period (august 1993-july 1996) at king faisal specialist hospital and research center (kfsh & rc) in riyadh revealed a wide spectrum of diseases associated with the isolation of five respiratory viruses. severity of disease ranged from mild upper respiratory illness to threatening lower respiratory illnesses including bronchiolitis and pneum ... | 1998 | 9924568 |
| group b strains of human respiratory syncytial virus in saudi arabia: molecular and phylogenetic analysis. | the genetic variability and circulation pattern of human respiratory syncytial virus group b (hrsv-b) strains, identified in riyadh during the winters of 2008 and 2009, were evaluated by partial sequencing of the attachment (g) protein gene. the second hypervariable region (hvr-2) of g gene was amplified by rt-pcr, sequenced and compared to representatives of different hrsv-b genotypes. sequence and phylogenetic analysis revealed that all saudi strains belonged to the genotype ba, which is chara ... | 2014 | 24370974 |
| genetic diversity in the g protein gene of group a human respiratory syncytial viruses circulating in riyadh, saudi arabia. | human respiratory syncytial virus (hrsv) is a frequent cause of hospitalization and mortality in children worldwide. the molecular epidemiology and circulation pattern of hrsv in saudi arabia is mostly uncharted. in the current study, the genetic variability and phylogenetic relationships of hrsv type a strains circulating in riyadh province were explored. nasopharyngeal aspirates were collected from hospitalized children with acute respiratory symptoms during the winter-spring seasons of 2007/0 ... | 2014 | 23884633 |
