Avian Group D Rotaviruses: Structure, Epidemiology, Diagnosis, and Perspectives on Future Research Challenges
In 1981, a new virus (virus 132) was described for the first time with morphological and biochemical similarities to rotaviruses (RVs), but without antigenic similarity to any of the previously known rotavirus groups. Subsequently, it was re-designated as D/132, and formed a new serogroup among rotaviruses, the group D rotavirus (RVD). Since their identification, RVs are the leading cause of en...
متن کاملA review of avian influenza in different bird species.
Only type A influenza viruses are known to cause natural infections in birds, but viruses of all 15 haemagglutinin and all nine neuraminidase influenza A subtypes in the majority of possible combinations have been isolated from avian species. Influenza A viruses infecting poultry can be divided into two distinct groups on the basis of their ability to cause disease. The very virulent viruses ca...
متن کاملMolecular detection and phylogenetic analysis of Avipoxvirus strains isolated from different bird species
The polymerase chain reaction (PCR) was used to amplify a 578 bp fragment of the poxvirus 4b core protein. Avipoxvirus (APV) specific DNA was detected in all 10 different isolates (each of which had been isolated from an epidemic) isolated from chicken; canary and mynah were collected from Tehran province. Sequencing was performed for 2 isolates as representative and the nucleotide sequence sho...
متن کاملDetection and Molecular Characterization of Avian Rotaviruses in Broiler Farms in Guilan
Background: Avian rotaviruses are one of the important agents of enteritis in birds and have a worldwide distribution. These viruses have an important role in runting and stunting syndrome in chickens. Objectives: The aim of this study was detection and molecular characterization of avian rotaviruses in broiler farms in Guilan province. Methods: In this study, 100 samples were collected on diff...
متن کامل[Molecular epidemiology of rotaviruses in preschool children].
Numerous epidemiological studies, conducted in both developed and developing countries, have shown that the rotavirus is an important aetiological agent in severe diarrhoeal diseases among preschool children. In recent years, different biochemical techniques for the genetic and phenotypic analysis of rotaviruses have been developed. The aim of this study was to define the biological and genetic...
