Rotaviruses are the most important etiological agent of acute gastroenteritis in young children worldwide. Among the first countries to introduce rotavirus vaccines into their national immunization programs were Belgium (November 2006) and Australia (July 2007). Surveillance programs in Belgium (since 1999) and Australia (since 1989) offer the opportunity to perform a detailed comparison of rot...

Complete sequences of genome segment 7 (S7) from six isolates of epizootic hemorrhagic disease virus serotype 1 (EHDV-1) and 37 isolates of serotype 2 (EHDV-2) were determined. These isolates were made between 1978 and 2001 from the southeast, mid-Atlantic, Midwest and intermountain United States. Analysis of the S7 sequence similarities showed 98.1% identity among the EHDV-1 isolates and 91.0%...

Abstract Background G12 rotaviruses were first observed in sub-Saharan Africa 2004 and since then have continued to emerge spread across the continent are reported as a significant human rotavirus genotype several African countries, both prior after vaccine introduction. This study investigated genetic variability of 15 strains associated with either P[6] or P[8] identified between 2010 2014 fr...

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...

study of genetic relationships is a prerequisite for plant breeding activities as well as for conservation of genetic resources. in the present study, genetic diversity among and within 15 iranian native ajowan(carum copticum l.) populations were determined using inter simple sequence repeat (issr) markers. twelve selected primers produced 153 discernible bands, with 93 (60.78%) being polymorph...

the results of mndo, am1 and pm3 semi-empirical calculations and hf/6-31g*, mp/6-31g*, mp2/6-311+g**, and b3lyp/6-311g** and qcisd/6-31g* ab initio methods for angle strain and conjugation effects in twist-boat, boat, and half-chair geometries of (z,z,z)-cycloocta-1,3,5-triene indicate that all methods, except pm3, predict wrong ordering of the conformations.

ab initio calculations at hf/6-31g* level of theory for geometry optimization and mp2/6-31g*//hf/6-31g*for total energy calculation are reported for z-cyclooctene (1). the most favorable conformation of 1 is theunsymmetric boat-chair (1-bc) geometry. potential energy profiles for two different boat-chair/boat-chairinterconversion processes were calculated. the process via a chair transition sta...

Background and Aims: Rotaviruses are the main cause of gastroenteritis in the young of human and a variety of animals in the world. Rotavirus G6 and G10 are the most prevalent genotypes in cattle worldwide, but are also found in human with possible origination from animals. Materials and Methods: In this work, we have detected the G6 and G10 genotypes of bovine rotaviruses isolated from di...

polymerase chain reaction and restriction fragment length polymorphism (pcr-rflp) and phylogenetic analysis were used for molecular identification of lactic acid bacteria (labs) isolated from apis mellifera. eighteen honeybee workers were collected from three different apiaries in west azerbaijan. labs from the gut of honeybees were isolated and cultured using routine biochemical procedures. ge...
