Myocarditis Associated with Reovirus in Turkey Poults

Avian Diseases, 2009
Myocarditis associated with reovirus was diagnosed in 17-day-old, male turkey poults, based on virus isolation, reverse transcriptase-polymerase chain reaction (RT-PCR), demonstration of reovirus antigen in the cytoplasm of mononuclear inflammatory cells and myocytes in the heart by immunohistochemistry (IHC), and reovirus particles in the endoplasmic ...

Isolation and Characterization of a Turkey Arthritis Reovirus

Avian Diseases, 2013
During the spring and summer of 2011, the Minnesota Veterinary Diagnostic Laboratory at the University of Minnesota received 14 submissions of 15-to-18-week-old tom turkeys that were recumbent with wing tip bruises ("wing walkers") and uni- or bilateral swelling of the hock (tibiotarsal) joints. Gastrocnemius or digital flexor tendons were occasionally

Efficacy of Five Commonly Used Disinfectants Against Turkey Arthritis Reovirus

Avian Diseases, 2015
Since late 2009, an unusual problem of reovirus-related lameness has been seen in market-age tom turkeys in the upper Midwest area of the United States. In this study, we determined the efficacy of five commonly used disinfectants (Virocid, Keno X5, Synergize, One Stroke, and Tek Trol) against turkey arthritis reoviruses (TARVs). For comparison, turkey

Turkey Origin Reovirus-Induced Immune Dysfunction in Specific Pathogen Free and Commercial Turkey Poults

Avian Diseases Digest, 2008
Recently, pathogenesis studies, using genetically distinct turkey-origin reoviruses (TRVs), revealed that poults infected with certain TRV isolates had moderate to severe bursal atrophy, suggesting virus-induced immune dysfunction. In order to characterize the effect of TRV infection on the turkey immune system, classical assays were undertaken to ...

Multiplex Real-Time Reverse Transcription–Polymerase Chain Reaction for the Detection of Three Viruses Associated with Poult Enteritis Complex: Turkey Astrovirus, Turkey Coronavirus, and Turkey Reovirus

Avian Diseases, 2005
Poult enteritis complex (PEC) is an economically important disease of young turkeys characterized by diarrhea, poor weight gain, and, in some cases, high mortality. Although PEC is considered to be a polymicrobial disease, numerous viruses, including turkey coronavirus (TCV), turkey astrovirus type 2 (TAstV-2), and avian reoviruses (ARVs), have been ...

Isolation and characterization of an enteric reovirus causing high mortality in turkey poults.

Avian Diseases, 1972
SUMMARY An enteric virus was isolated from several commercial flocks of 4-to-6-week-old turkey poults with about 30% mortality. No gross pathological lesions were observed in either sick or dead birds. Pathogenicity of the isolant was established by transmission studies with both intestinal filtrate and cell-culture material.

Isolation of a Reovirus from Poult Enteritis and Mortality Syndrome and Its Pathogenicity in Turkey Poults

Avian Diseases, 2002
Poult enteritis and mortality syndrome (PEMS) is an acute, infectious intestinal disease of turkey poults, characterized by high mortality and 100% morbidity, that decimated the turkey industry in the mid-1990s. The etiology of PEMS is not completely understood.

Retrospective Study of Myocarditis Associated With Reovirus in Turkeys

Avian Diseases Digest, 2010
The myocarditis associated with reovirus in commercial turkeys was studied retrospectively. Fifty-two cases were identified between 1991 and 2009. The lesions occurred in four different poultry companies in California and affected male and female turkeys with an average age of 19 days.

Gastrointestinal Transit Times in Normal and Reovirus-Inoculated Turkeys

Avian Diseases, 1985
Brilliant pigment powder was used to measure minimum gastrointestinal transit times (GTT) in control and cloned-reovirus-inoculated turkey poults. Compared with controls, inoculated poults had longer GTT at 120 hr (P less than 0.05) but not at 24 and 72 hr after receiving a single oral dose of cloned reovirus.
