RESUMO
Human bocavirus [HBoV] is a major etiology of lower respiratory tract infection [LRTI] in young children. We tested 149 patients admitted to King Fahd Hospital of the University with diagnosis of LRTI. Viremia caused by the different studied viruses was detected in 31.5% of the total cases by Real-time Polymerase chain reaction. We report five patients who were positive for HBoV in serum samples. Clinical presentation ranged from mild to severe disease as one of them required admission to intensive care unit. Wheezing was a striking feature in most of our patients, but fever was not a consistent finding
RESUMO
To assess the prevalence of HIV-1 genetic subtypes in Saudi Arabia in samples that are serologically positive for HIV-1, and compare the HIV-1 genetic subtypes prevalent in Saudi Arabia with the subtypes prevalent in other countries. Thirty-nine HIV-1 positive samples were analyzed for HIV-1 subtypes using molecular techniques. The study is a retrospective study that was conducted in Dammam, Kingdom of Saudi Arabia, and in Abbott laboratories [United States of America] from 2004 to 2007. All samples were seropositive for HIV-1 group M. Of the 39 seropositive samples, only 12 were polymerase chain reaction positive. Subtype C is the most common virus strain as it occurred in 58% of these samples; subtype B occurred in 17%; and subtypes A, D and G were found in 8% each. The phylogenetic tree was also identified for the isolates. Detection of HIV subtypes is important for epidemiological purposes and may help in tracing the source of HIV infections in the Kingdom of Saudi Arabia
