BACKGROUND This work demonstrates successful propagation of HCV in HepG2 and human blood cells as well as viral shedding into their culture media. The influence of Schistosoma mansoni crude soluble egg antigens (SEA) on the rate of viral propagation in both mammalian cells was also monitored. METHODOLOGY HepG2 cells were inoculated with HCV viremic human sera and some wells were exposed to HC...

BACKGROUND Rotavirus gastroenteritis (RVGE) constitutes a significant burden of pediatric disease. Knowledge of currently cocirculating rotavirus genotypes is required to help guide immunization strategies. METHODS During the 2004-2005 RVGE season, a prospective, multicenter, observational study of RVGE was conducted in children <5 years of age seeking health care in primary care, emergency d...

This study was designated to describe clinical and biological features of patients with a suspected diagnosis of dengue fever/dengue hemorrhagic fever during an outbreak in Central Vietnam. One hundred and twenty-five consecutive patients hospitalized at Khanh Hoa and Binh Thuan Provincial hospitals between November 2001 and January 2002 with a diagnosis of suspected dengue infection were inclu...

We developed and characterized a stable Vero cell line constitutively expressing Peste des petits ruminants virus (PPRV) hemagglutinin (H) protein and assessed its potential use as diagnostic antigen in enzyme-linked immunosorbent assay (ELISA). PPRV H gene of the vaccine strain (Sungri-96) was amplified by reverse transcription (RT)-PCR, cloned into a eukaryotic expression vector (pTarget), an...

abstract beet soilborne virus (bsbv) is a member species of the genus pomovirus with rigid rod particles and 3 positive single stranded rnas. the virus is transmitted by polymyxa betae and restricted to chenopodiaceae. a survey was conducted in 2005 for identification of bsbv in northern khorasan province. samples showing yellowing, elongated and upright petioles with narrow leaf lamina and hai...

OBJECTIVE Growth arrest-specific 6 (Gas6) is a newly discovered vitamin K-dependent protein, which is a ligand for TAM receptors [Tyro3 (Sky), Axl, and Mer] from the tyrosine kinase family. Gas6 knockout mice were resistant to venous and arterial thrombosis. There are contradictory reports on the presence of Gas6 and its receptors in mouse platelets. The objective of this study was to investiga...

Rotavirus ribonucleic acid (RNA) was extracted from ten faecal samples of diarrhoeic calves positive for group A rotavirus by enzyme-linked immunosorbent assay (ELISA). A portion of the extracted RNA was run in polyacrylamide gel to determine the presence of rotaviral RNA and the rest subjected to reverse transcriptase-polymerase chain reaction (RT-PCR) to generate the near full length VP7 gene...
