| Turkey pseudo enterovirus 1 and 2. Abstract from 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. References Andral, B. and Toquin, D. (1984).
