||Turkey pseudo enterovirus 1 and 2.
Andral and Toquin (1984)...
Forty-nine sick turkeys (from 31 flocks), 2- to 6-week-old, were
examined. They had enteritic and respiratory signs. Direct electron
microscopy, inoculation of embryonated eggs by the yolk sac route
and inoculation of young SPF turkeys with materials from affected
turkeys showed in several cases presence of picornalike virus. Two
strains of virus were isolated. Examination of infected yolk sac
cells by electron microscopy revealed lesions similar to those
observed with picornavirus infection.
Abstract from Andral et al. (1990)...
A strain of picorna-like virus cultivated in the yolk sac membranes
of inoculated eggs was inoculated into 6-day-old turkeys. Clinical
signs and mortality were observed between two and three weeks. Virus
was seen in the faeces. The post-mortem and histological changes in
the organs of infected birds were highly suggestive of a viral
aetiology. The virus was reisolated from organs of sick and dead
poults by inoculating SPF embryonated eggs.
