“…The post‐mortem examination of some culled birds did not reveal any lesions that might raise the suspicion of the presence of REV. The finding of sporadic infection in turkey flocks supports earlier reports (Sarma et al., 1975; Solomon et al., 1976; McDougall et al., 1978; Witter et al., 1982) and indicates that REV is circulating in turkey flocks in Germany. The source of the REV exposure in the seropositive flocks is unknown.…”

Four meat turkey and one turkey breeding¯ocks were surveyed for antibodies against reticuloendotheliosis virus (REV) at different intervals using commercial enzyme-linked immunosorbent assays. In addition, serum samples collected from 18¯ocks at different ages were also tested for antibodies against REV. No antibodies were detected in any of the four meat turkey¯ocks that were surveyed. In the breeder¯ock, 20 % of tested samples from 1-day-old poults were positive. Between the fourth and 12th weeks all samples that were tested yielded negative results. At 16 weeks of age 15 % of samples yielded a positive reaction, but antibodies could not be detected 4 weeks later. Examination of serum samples from 18 different¯ocks at various ages revealed that antibodies could be detected in ®ve¯ocks. The percentage of positive sera per¯ock ranged between 10 and 40 %.

“…More recently Paul et al (1976) isolated REV from two outbreaks of turkey leukosis and reproduced the disease in turkeys by inoculation of cell free filtrates. Solomon et al (1976) also isolated REV from three turkey flocks, two of which had a history of mortality from neoplastic disease. During 1975 leukosis occurred in a turkey breeding organisation in England.…”

SUMMARYThe clinical features and lesions are described for an outbreak of a leukosis in an integrated turkey breeding organisation. Turkeys had diarrhoea between 8 and 12 weeks of age and from 15 weeks onwards leukosis lesions appeared. A greater than 20% mortality occurred in most affected flocks. The disease was characterised clinically by enlargement of the liver and to a lesser degree other organs. Microscopically the lesions consisted of proliferations of lymphoblastoid cells. Reticuloendotheliosis virus (REV) was isolated from ailing culled turkeys and from cell cultures prepared from embryonated eggs produced by a flock with this disease. In affected flocks a REV was also isolated from turkeys 8 to 12 weeks of age in which enteritis was the main clinical feature. Inoculation of 1-day-old turkeys with this isolate of REV produced a syndrome of enteritis followed by leukosis. Antibody to REV was detected in turkeys surviving experimental inoculation and in the two flocks of turkeys examined, one of which had experienced considerable leukosis mortality.

“…Reticuloendotheliosis viruses are known to infect a number of avian species including chicken, duck, quail, pheasant and turkey. Natural reticuloendotheliosis virus (REV) infection and disease have been recognized in turkey¯ocks in Israel (Ianconescu et al, 1979), the United Kingdom (McDougall et al, 1978) and the United State of America (Sarma et al, 1975;Solomon et al, 1976;Witter and Glass, 1984). In some turkey¯ocks REV is endemic (Witter, 1997).…”
