A robust, ultrasensitive, and accurate quantitative assay was developed for avian reovirus (ARV) with the Light Cycler SYBR Green-based real-time reverse transcription-PCR (real-time LC RT-PCR). The assay exhibited high specificity as all negative controls and other avian pathogens, such as Newcastle disease virus (NDV), infectious bronchitis virus (IBV), infectious bursal disease virus (IBDV),...

Although muscovy duck reovirus (DRV) shares properties with the reovirus isolated from chicken, commonly named avian reovirus (ARV), the two virus species are antigenically different. Similar to the DRV sigmaB-encoded gene (1201 bp long) previously identified, the three other double-stranded RNA small genome segments of DRV have been cloned and sequenced. They were 1325, 1191 and 1124 bp long, ...

Laboratory column studies were conducted at the Utah Water Research Laboratory, Logan, Utah, to evaluate reovirus removal from drinking water supplies by slow-rate sand filtration (SSF). Columns, constructed to simulate a full-scale SSF field operation, were inoculated with reovirus at ca. 1,000-times-greater concentrations than those typically found in domestic sewage. Reovirus removal and ina...

Acute respiratory tract infections are leading causes of morbidity in poultry farms throughout the world. Avian pneumovirus (APV), avian influenza virus (AIV), and Newcastle disease virus (NDV) have been recognized as the most important pathogens of both chicken and turkeys. Single-virus reverse transcription-polymerase chain reaction (sRT-PCR) assays are used extensively to detect these viruse...

PURPOSE This study combined systemic administration of the oncolytic reovirus type 3 Dearing (reovirus) with chemotherapy in human subjects. We aimed to determine the safety and feasibility of combining reovirus administration with gemcitabine and to describe the effects of gemcitabine on the antireoviral immune response. EXPERIMENTAL DESIGN Patients received reovirus in various doses, initia...

Enzyme-linked immunosorbent assays were developed for the quantitation of anti-reovirus immunoglobulin G (IgG), IgA, and IgM in serum. The assays were specific, sensitive, and reproducible and measured antibodies to the reovirus group antigen. They should permit diagnosis of recent reovirus infection and longitudinal study of the development of reovirus group antibodies.

Enteric viruses play an important role in the Brazilian poultry industry due to the economic impact of resulting low yields of broilers, layers, and breeders. The most common enteric viruses affecting commercial flocks in Brazil include Fowl Adenovirus of group I (FAdV-I), Chicken Parvovirus (ChPV), Chicken Astrovirus (CAstV), Avian Nephritis Virus (ANV), Infectious Bronchitis Virus (IBV), Avia...

Mycoplasma synoviae (MS), causing respiratory diseases, arthritis, and eggshell apex abnormalities in avian species, is an important pathogen in the poultry industry. Implementation of a biosecurity plan is important in MS infection management. Working on a field-deployable POCKIT™ device, an insulated isothermal polymerase chain reaction (iiPCR) assay has a potential for timely MS detection on...

Reovirus, a double-stranded RNA virus, can infect many types of cancer cells and cause oncolysis. Mammalian reovirus has exhibited promising anticancer activity in clinical trials and holds great advantages and promise as an anticancer agent. Reovirus is not associated with any serious human diseases, naturally targets and destroys tumors, and lacks the DNA synthesis stage, thus avoiding potent...
