Group A rotavirus (GARV) genes (the VP7 and NSP3 genes) in acute-phase cerebrospinal fluid (CSF), sera and stool samples from 6 children with convulsions accompanied by GARV gastroenteritis were investigated by reverse transcription-polymerase chain reaction (RT-PCR). When the VP7 gene was amplified from the samples, the G genotype (G type) of GARV was determined by RT-PCR. GARV genes were dete...

We report the detection and molecular characterization of a rotavirus strain, 10733, isolated from the feces of a buffalo calf affected with diarrhea in Italy. Strain 10733 was classified as a P[3] rotavirus, as the VP8* trypsin cleavage product of the VP4 protein revealed a high amino acid identity (96.2%) with that of rhesus rotavirus strain RRV (P5B[3]), used as the recipient virus in the hu...

Rotavirus remains a major cause of diarrhea in infants and young children especially in developing countries. Monitoring changes in rotavirus strains is necessary to assess the potential effectiveness of vaccines in specific geographic locations. This project aimed at monitoring the epidemiological status of rotavirus among Thai children. A total of 73 positive fecal samples for rotavirus were ...

Background. Group A rotavirus (RVA) infection is the major cause of acute gastroenteritis (AGE) in young children worldwide. Introduction of two live-attenuated rotavirus vaccines, RotaTeq® and Rotarix®, has dramatically reduced RVA associated AGE and mortality in developed as well as in many developing countries. High-throughput methods are needed to genotype rotavirus wild-type strains and to...

The efficacy of all chemotherapeutic agents is limited by the occurrence of drug resistance. For etoposide (VP-16), increased expression of MDR-1 or MRP and alterations in topoisomerase IIalpha have been shown to confer tolerance. To further understand resistance to VP-16, three sublines, designated MCF-7-VP17, ZR-75B-VP13, and MDA-MB-231-VP7, were initially isolated as single clones from paren...
