Rotavirus is a leading cause of dehydrating diarrhea and death among infants and children globally, particularly in communities of the developing world. While numerous studies have described the complex relationships among infectious diarrhea, growth faltering, and poverty, the impact of nutritional status on susceptibility to rotavirus diarrhea is not well understood. In a longitudinal study c...

The decision to develop rotavirus vaccines was predicated on the extensive burden of rotavirus disease among children worldwide. US reports on nationwide hospitalizations (1979-1992) and deaths (1968-1991) due to diarrhea and weekly reports of rotavirus infection by 74 laboratories were reviewed to estimate the burden of rotavirus disease, identify epidemiologic trends, and consider methods for...

Background: Rotavirus infection is one of the most common gastroenteritis in the world, and a million cases are registered to enter hospital every year. Promyelocytic leukemia proteins (PMLs) are IFN-up-regulated proteins, and one of their critical functions is working as antiviral proteins. Recently, promyelocytic leukemia isoform II (PML-II) has been depicted as an isoform responsible for the...

Background: Enteric viruses, particularly human rotavirus and norovirus, have been shown to replace bacteria and parasites, as the most common pathogens responsible for acute diarrhea. However, there are still few epidemiological data on the simultaneous occurrence of these viruses in Iran. In this regard, the aim of this study was to assess the useful epidemiological data on the gastroenteriti...

BACKGROUND Rotavirus gastroenteritis is the major cause of morbidity and mortality in infants and young children worldwide. Safe and effective rotavirus vaccine is needed to have significant impact on severe rotavirus gastroenteritis. Currently, two live oral rotavirus vaccines have been licensed in many countries. Knowledge on distribution of human rotavirus of G and P types are essential befo...

The immune response elicited by the rotavirus nonstructural protein NSP4 and its potential role in protection against rotavirus disease are not well understood. We investigated the serological response to NSP4 and its correlation with disease protection in sera from 110 children suffering acute diarrhea, associated or not with rotavirus, and from 26 children who were recipients of the rhesus ro...

BACKGROUND Human rotaviruses are the most important agents for severe dehydrating diarrhea in children below 5 years old. Rotaviruses (RV) is a serious public health problem in developing and developed countries. OBJECTIVES The aim of this study was to determine the prevalence of rotavirus infection and their genotypes in children younger than 5 years of age with acute diarrhea in Ahvaz, Iran...

Two effective vaccines for rotavirus infection will be available near future in Japan and data on the burden of rotavirus disease and the circulating rotavirus strains are urgently needed. To obtain these data, we set up active rotavirus hospitalization surveillance in three cities, Tsu, Matsusaka, and Ise in Mie Prefecture, Japan. From November 1, 2007 through October 31, 2009, we enrolled...

BACKGROUND To assess the incidence and economic burden of rotavirus diarrhea and the potential cost-effectiveness of a rotavirus immunization program in rural Zhengding County in Hebei Province, China. METHODS Population-based surveillance was conducted during the peak season for diarrhea among children who were <5 years of age in Zhengding County from 14 October 2004 through 19 January 2005....

A series of expression cassettes which mediate secretion or surface display of antibody fragments was stably integrated in the chromosome of Lactobacillus paracasei. L. paracasei producing surface-anchored variable domain of llama heavy chain (VHH) (ARP1) directed against rotavirus showed efficient binding to rotavirus and protection in the mouse model of rotavirus infection.
