Group C rotaviruses are fastidious in their in vitro cell culture requirements. Recent serosurveys indicate that antibody to group C rotavirus is present in 3-45% of the human population in certain geographic locations, suggesting that rotavirus group C infection is more prevalent than previously believed and that the low rate of detection of these agents is probably due to the lack of sensitiv...
this thesis basically deals with the well-known notion of the bear-invariant of groups, which is the generalization of the schur multiplier of groups. in chapter two, section 2.1, we present an explicit formula for the bear-invariant of a direct product of cyclic groups with respect to nc, c>1. also in section 2.2, we caculate the baer-invatiant of a nilpotent product of cyclic groups wuth resp...
Background: Acute gastroenteritis is a major cause of morbidity and mortality among children in developing countries. Rotaviruses are recognized as the most common etiologic factors of gastroenteritis. In this study, we determined the epidemiologic features, clinical symptoms and molecular structure of rotavirus VP4(P) genotypes in children with acute diarrhea in Bahrami Hospital in T...
Accepted: 01/05/2015 Abstract Group A rotaviruses play an important role in causing gastroenteritis and mortality in buffalo calves. To investigate the epidemical characteristics and prevalence of bovine rotavirus (Group A rotavirus) in Punjab, 120 fecal samples were collected from buffalo calves (n=93) and cow calves (n=27) up to 3 months age group calves exhibiting diarrhoea during the period...
BACKGROUND Rotavirus still remains the major cause of diarrhea in children below 5 years. No data on rotavirus epidemiology is available in the Northern regions of Cameroon. We aimed to determine the prevalence of group A rotavirus (RVA) in children below 5 years with diarrhea in two regions of Northern Cameroon (North West and Far North Regions) so as to improve our knowledge on the burden of ...
Group A rotaviruses were first detected in pigs suffering from diarrhea in 1975. It is generally accepted that multiple rotavirus strains are present in most if not all conventional swine herds. Rotavirus infections are very prevalent and are commonly associated with diarrhea in suckling and weaned pigs. Early studies also demonstrated that porcine rotaviruses are physically and serologically s...
background rotaviruses are the most common cause of viral gastroenteritis in newborns and young children. the current study intended to investigate the presence of rotavirus antigen in fecal specimens of children with acute diarrhea, to determine its prevalence and to examine its distribution pattern by age, gender and season. objectives this was a retrospective investigation of cases with rota...
Besides group A rotaviruses, group B and C rotaviruses have been detected as the cause of diarrheal diseases in pigs. Of a set of 329 faecal samples from pigs, 16 samples were selected in which rotavirus was detected by electron microscopy and at the same time group A rotavirus was excluded by ELISA method. Rotaviruses were assayed using specific primers for detection of group B and C rotavirus...
Background & Aims: Diarrheal diseases are one of the major causes of morbidity and mortality in infants and toddlers in developing countries and Rotavirus is the single most important cause of severe infantile gastroenteritis worldwide. This study was conducted to estimate the frequency and clinical manifestations of rotavirus infection in children below 3 years old with acute gastroenteritis r...
