Rotaviruses were concentrated from 8-liter samples of raw domestic sewage and sewage-polluted creek water by adsorption to and elution from positively charged microporous filters (Zeta Plus 60S), followed by ultracentrifugation of the filter eluates. Indirect immunofluorescence and direct immunoperoxidase methods allowed detection and enumeration of rotavirus in 6 (20.6%) of 29 sewage samples a...

Fecal concentrations of pyruvate kinase isoform M2 (M2-PK) and calprotectin (FC) serve as biomarkers of inflammation of gastrointestinal mucosa. The value of M2-PK in discriminating between patients with viral and bacterial acute diarrhea (AD) is currently unknown. We analyzed M2-PK and FC concentrations in fifty hospitalized children with AD (29 of which were caused by rotavirus and 21 by Salm...

BACKGROUND Rotavirus gastroenteritis results in significant morbidity and mortality in Indian children. Although there are numerous studies on rotavirus diarrhea, there are few reports on antigenemia and extraintestinal presentations in these populations. METHODS Following screening for rotavirus antigen of stool samples from children with and without acute gastroenteritis with a commercial e...

Rotaviruses, the cause of life-threatening diarrhea in humans and cattle, utilize a functional homolog of poly(A) binding protein (PABP) known as nonstructural protein 3 (NSP3) for translation of viral mRNAs. NSP3 binds to viral mRNA 3' consensus sequences and circularizes the mRNA via interactions with eIF4G. The X-ray structure of the NSP3 RNA binding domain bound to a rotaviral mRNA 3' end h...

BACKGROUND Rotavirus is a common infection causing 450,000 deaths annually primarily in children 5 years and below. Despite the high burden of disease, little is known about the epidemiology of rotavirus in Libya. The aim of this study was to estimate the rotavirus disease burden among Libyan children. METHODS A cross-sectional study was carried out prospectively among children 5 years old an...

From March 1983 to February 1985, rectal swabs were collected from the black infants admitted to the gastroenteritis unit at Ga-Rankuwa Hospital, Pretoria, Republic of South Africa, to investigate the prevalence of rotavirus-associated gastroenteritis. Overall, 23.1% of the patients tested were found to be positive for rotaviral illness; a definite seasonal pattern emerged, showing a marked inc...

BACKGROUND Achillea kellalensis, which is frequently used by Chaharmahal va Bakhtiarians residing in, Southwest of Iran, as a traditional herbal medicine for the treatment of acute diarrhea, has been selected to examine its antiviral activities against bovine rotavirus and cell toxicity activity in MA-104 cells. OBJECTIVES The aim of this study was to evaluate the in vitro cytotoxic and anti-...

BACKGROUND Rotavirus infection causes a significant proportion of diarrhea in infants and young children worldwide leading to dehydration, hospitalization, and in some cases death. Rotavirus infection represents a significant burden of disease in developing countries, such as those in South Asia. METHODS We conducted a meta-analysis to examine how patterns of rotavirus infection relate to tem...

BACKGROUND Rotaviral diarrhea (RD) has been associated with the biodiversity of the fecal microbiota in infants; however, the differences in the biodiversity of the fecal microbiota between infants with RD and healthy (H) infants have not been clearly elucidated. OBJECTIVES This study aimed to reveal the changes in the biodiversity of the fecal microbiota of infants with RD. PATIENTS AND ME...
