the etiology of acute diarrhea was studied in 915 children under 5 years of age between march 1986 and august 1987, in 7 hospitals in tehran. 65 healthy children in similar age groups served as controls. rotavirus was found in 25% of the patients and 1.5% of controls with the highest detection rate occurring in the 7-24 month age group (28%) and declining beyond 25 months of age (5%). the infec...
Rotavirus is the leading cause of severe acute gastroenteritis among children worldwide. Despite effective vaccines, inexpensive alternatives such as probiotics are needed. The aim of this study was to assess the ability of probiotic candidate Bifidobacterium thermophilum RBL67 to inhibit rotavirus infection. Bacterial adhesion to intestinal cells and interference with viral attachment were eva...
Sulfated colominic acid exhibited suppressive effects on SA11 (simian rotavirus)- and MO (human rotavirus)-infections, but not on Wa (human rotavirus)-, Sabin 1 (poliovirus 1)-, and Nancy (coxsackie B3 virus)-infections, in vitro. The infection of SA11 was found to be inhibited by mixed treatment and early posttreatment with sulfated colominic acid, but not by pretreatment, by plaque assay and ...
An enzyme-linked immunosorbent assay for the diagnosis of rotavirus infection in calves is described. The assay was more efficient for the detection of rotavirus antigens in calf feces than were electron microscopy and immunoelectroosmorphoresis.
BACKGROUND/PURPOSE Viral infections are the most common causes of acute infectious diarrhea in the pediatric population. To explore any possible microbial etiologies of acute gastroenteritis in children, we detected stool viral antigen including rotavirus, adenovirus, norovirus and astrovirus. We also studied the possible precipitating factors. METHODS During a period of 1 year (from October ...
Rotavirus is the leading cause of severe and dehydrating diarrhea in children aged under 5 years. We undertook this hospital-based surveillance study to examine the possible relationship between the severity of diarrhea and the various G-group rotaviruses circulating in India. Stool samples (n = 2,051) were systematically collected from 4,711 children aged <5 years admitted with severe acute ga...
Rotavirus is the most important cause of infantile gastroenteritis. Since in vivo mucosal responses to a rotavirus infection thus far have not been extensively studied, we related viral replication in the murine small intestine to alterations in mucosal structure, epithelial cell homeostasis, cellular kinetics, and differentiation. Seven-day-old suckling BALB/c mice were inoculated with 2 x 10(...
Quantitative Microbial Risk Assessment (QMRA) models with 10,000 Monte Carlo simulations were applied to ascertain the risks of rotavirus and Ascaris infections for farmers using different irrigation water qualities and consumers of lettuce irrigated with the different water qualities after allowing post-harvest handling. A tolerable risk (TR) of infection of 7.7 x 10(-4) and 1 x 10(-2) per per...
To characterize rotavirus G and P genotypes circulating among infants and young children hospitalized with severe diarrhea in a university hospital in Gyeonggi province, Korea, and to examine any association of the genotypes and nosocomial infections, we genotyped 103 isolates of rotavirus by multiplex RT-PCR. In July 2001-June 2002, we found that globally common strains constituted 64.2% (G2P[...
