“…However, using monoclonal antibodies (Cui et al, 1986(Cui et al, , 1988, REV isolates can be classed into three distinct subtypes, 1, 2 and 3 (Chen et al, 1987). REV infects chickens, Attwater prairie chickens, Greater prairie chickens, turkeys, ducks, geese, pheasants, quail, and probably many other avian species (Witter et al, 1970(Witter et al, , 1981Purchase et al, 1973;Dren et al, 1983Dren et al, , 1988Dren et al, , 1998Fadly et al, 1996a;Crespo et al, 2002;Chen et al, 2006;Zavala et al, 2006;Barbosa et al, 2007;Fadly et al, 2008b;Lin et al, 2009). Based on virus or antibody detection assays, REV infection has been shown to be common, if not ubiquitous, in most countries (Witter & Johnson, 1985;Bagust et al, 1993;Fadly et al, 2008b).…”

Nine reticuloendotheliosis virus (REV) isolates obtained from broiler breeders, turkeys, and prairie chickens located in three different geographical regions in the USA, and three isolates obtained from known contaminated live-virus vaccines were characterized using polymerase chain reaction (PCR) and indirect immunofluorescence (IFA) assays. All isolates were propagated in chicken embryo fibroblasts obtained from a specific pathogen free breeder flock. PCR analysis of all 12 isolates resulted in the amplification of the 291-bp REV long-terminal repeat region (LTR); none of the isolates exhibited a different pattern or shift from the expected PCR product of REV LTR. The subtype of the REV isolates was determined by IFA using REV-specific monoclonal antibodies, 11B118.22, 11C237.8, and 11D182. Results from sub-typing indicated that all nine isolates from broiler breeders, turkeys, and prairie chickens belonged to subtype 3, and are antigenically related to the chick syncytial virus (CSV) strain of REV, the prototype of subtype 3 REV. In contrast, the three isolates from contaminated vaccines were classified as subtype 2, and were antigenically related to spleen necrosis virus (SNV) strain of REV, the prototype of subtype 2 REV. Three isolates representing REV isolated from broiler breeders, turkeys, and prairie chickens were cloned and further evaluated by DNA sequence analysis of the envelope gene. Results from DNA sequence analysis confirmed those from sub-typing and indicated that the three REV isolates representing those from broiler breeders, turkeys, and prairie chickens are closely related to CSV of REV, with an amino acid homology of 98% or greater as compared with SNV with an amino acid homology of 95% or less. Data from this study clearly indicate that subtype 3 is the most common subtype of REV circulating in three different avian species, namely broiler breeders, turkeys and prairie chickens, located in three different geographical regions in the United States.

“…Neoplastic lesions were described in subcutaneous tissue and internal organs of captive greater prairie chickens (Tympanuchus cupido pinnatus) (Drew et al, 1998), Attwater's prairie chickens (Tympanuchus cupido attwateri) (Drew et al, 1998), and ring-necked pheasants (Phasianus colchicus) (Dren, 1983). In addition, nodules along the digestive tract combined with neoplastic lesions in other internal organs have been reported in Japanese quail (Coturnix coturnix japonica) (Schat et al, 1976).…”

A large commercial flock of Hungarian partridge (Perdix perdix) experienced elevated mortality associated with a wasting disease in May 1998. Postmortem examination of females consistently revealed a distended crop and abnormal gray-white tissue infiltrating the wall of the crop and thoracic esophagus. Neoplasia in male partridge was observed in the liver. Microscopic examination of the crop and thoracic esophagus revealed transmural masses of immature lymphocytes with frequent mitotic figures. Similar cells were observed in the liver of affected males. Virus particles consistent in size and morphology with reticuloendotheliosis virions were observed in neoplastic lymphoid cells via electron microscopy. Reticuloendotheliosis virus was isolated from each of four blood samples. This disease has not previously been reported in Hungarian partridges. Hungarian partridge may represent a potential reservoir of infection for other gamebirds, including prairie chickens.

“…The REV group initially included isolates from turkeys (Paul et al, 1977), ducks (Li et al, 1983) and chickens (Purchase et al, 1973). Later, isolates from geese, Japanese quail and pheasants (Dren et al, 1983) were made. All REV isolates are non-defective, with the exception of REV-T which contains the v-rel oncogene (Robinson & Twiehaus, 1974).…”

SUMMARYCongenital transmission of reticuloendotheliosis virus (REV) is known to occur when one of the parents in either tolerantly infected or viraemic; however little attention has been paid to replication of the virus within the embryo itself. In this study five non-defective and one replication-defective strain of REV were inoculated into the yolk sac of 6-day-old embryonated eggs. With the exception of one non-defective strain, the others induced embryonic deformation or lesions that were apparent on the day of hatching. Replicative integration of the provirus was determined for several tissues of each embryo by the polymerase chain reaction employing a set of primers specific for the long terminal repeat. Indirect immunofluorescent detection of whole virus was performed on the same tissues in parallel. A variation in replication was found among the strains and between embryos inoculated with the same strain of virus, therefore, the results for each virus strain were expressed as cumulative values. The liver and spleen were the most commonly affected organs, while the bursa of Fabricius and thymus supported viral replication to a lesser degree. Detection of proviral DNA in blood was evidence that the chicks had been congenitally infected. Such an infection would likely lead to tolerance. Isolates REV-S and REV-D were found to replicate to the highest extent, and they also caused lesions in the commercial type of embryonated eggs, while REV-S and mainly the REV-T prototype were pathogenic for the SPF embryonated eggs.
