Rotavirus genotype G12 strains were detected for the first time among newborns with asymptomatic rotavirus infection (74% of 39 rotavirus strains isolated from the infected infants were genotype G12) in the nursery of the All India Institute of Medical Sciences during a period from 2005 to 2006. Sequence analysis of the VP7 genes from these neonatal strains indicated a high level of homology to...

The impact of rotavirus, the most prevalent diarrheal pathogen in young children worldwide, may be reduced by either a recently approved vaccine or others in development. The dynamics of rotavirus infections are studied using a simple mathematical model that includes the impact of breast feeding, seasonality and the possibility of control via vaccination. Data from Australia are fitted to a mod...

This article describes the role of bovine coronavirus, rotavirus and Cryptosporidium parvum in an outbreak of beef calf diarrhea in Presidente Epitácio, São Paulo State. Two out 9 fecal samples were positive to BCoV, 6 to C. parvum and 6 to rotavirus, with 4 rotavirus-C. parvum co-infections, 1 BCoV-C. parvum co-infection and 1 rotavirus-BCoV co-infection. These results show the need for a deta...

BACKGROUND Pathogenesis of neonatal hepatitis relates to various underlying causes including viral infections. Both hepatotropic and non-hepatotropic viruses may induce liver failures in infants before birth, during delivery, or shortly after birth. OBJECTIVES The tissue impact of HCMV, HSV, HBV, HCV, and rotavirus and adenovirus infections was evaluated in studied infants with neonatal hepat...

The effect of circulating passive antibody on immunity to bovine rotavirus infections in neonatal calves was investigated. In the first experiment, rotavirus antibody titers in the small intestinal lumina of 5- and 10-day-old calves with a wide range of serum rotavirus antibody titers were determined. Neutralizing antibody was present in the small intestinal lumina in titers that correlated wit...

a 1:1 matched case-control study of calves under 1 month of age was carried out by weekly visits to 7 dairy farms in mashhad from may 2008 to october 2008. fecal samples were collected from a total of 112 calves with clinical signs of diarrhea and from 112 matched animals without clinical signs of diarrhea as assessed by a scoring system. the samples were investigated for the presence of rotavi...

Rotavirus is a major cause of diarrhoea1 disease in young children and animals. Worldwide, it is responsible for 870,000 human deaths per year, primarily in the developing countries and causes significant economic losses in agriculture [ I ,2]. Natural infections in infancy prevent severe diarrhoea when subsequently challenged [3]. The current goal of rotavirus vaccination is to induce immunity...

INTRODUCTION Rotavirus (RV) infection is the most common cause of gastroenteritis in children. This paper identifies the most common genotypes of rotaviruses isolated from children hospitalized with gastroenteritis and attempts to determine any relationship between infection with a certain rotavirus genotype. MATERIAL AND METHODS The investigated group consisted of 68 consecutive children wit...

The global epidemiological landscape of childhood acute gastroenteritis (AGE) is changing after the introduction of 2 effective rotavirus vaccines in 2006. A comprehensive evaluation for viral etiology of childhood AGE in Taiwan, where rotavirus vaccination was provided by the private sector since 2006, is lacking.From 2009 to 2011, children younger than 5 years of age with AGE who were hospita...
