Isolation and molecular characterization of newly emerging avian reovirus variants and novel strains in Pennsylvania, USA, 2011–2014
Avian reovirus (ARV) infections of broiler and turkey flocks have caused significant clinical disease and economic losses in Pennsylvania (PA) since 2011. Most of the ARV-infected birds suffered from severe arthritis, tenosynovitis, pericarditis and depressed growth or runting-stunting syndrome (RSS). A high morbidity (up to 20% to 40%) was observed in ARV-affected flocks, and the flock mortali...
متن کاملIn vitro characterization of an avian reovirus vaccine strain.
In vitro studies were performed to characterize the vaccine strain, designated P100, derived from the arthrogenic reovirus isolate, S1133, by cold adaptation. P100 appeared to be temperature sensitive, shown by a marked drop in titer and efficiency of plaquing after incubation at 41 degrees. Studies indicated that genomic double-stranded RNA and protein synthesis were severely restricted at the...
متن کاملAvian reovirus infections.
Avian reoviruses are ubiquitous among poultry flocks. Although infection is usually present without disease, reoviruses may occasionally be involved in several disease syndromes of which viral arthritis/tenosynovitis in chickens is the most important, particularly in broiler breeds. While reoviruses have been isolated from turkeys and several other species of birds with various conditions, the ...
متن کاملGenotypic characterization of HIV variants from PBMCs and spermatozoa
Background Several studies have shown that detectable levels of HIV are observed in semen in spite of undetectable viral load in blood following antiretroviral therapy (ART). Also, different HIV variants have been detected in blood and semen of the same individual, suggesting that drugs may not be uniformly effective to control the viral load and infectivity in different tissues and secretions,...
متن کاملGenetic diversity in twenty variants of the avian polyomavirus.
To determine if different pathotypes of the avian polyomavirus (APV) exist and to compare the genomes of APVs originating from different geographic areas, dates, and species of birds, the partial sequences of 18 APVs were determined. New viral sequences were compared with three published APV sequences. Two of the new viruses had identical sequences. Forty point mutations were found at 31 loci. ...
