Implication

May prompt CAstV screening in affected hatcheries; leaves open causal proof and control trials.

Structured PICO

P
Population
Organ samples from dead-in-shell embryos and 1-day-old chicks from a 30-week-old breeder flock in Poland; 10-day-old embryonated specific pathogen free (SPF) chicken eggs; 8-day-old SPF chicken eggs (n=10)
I
Intervention
Inoculation with Chicken astrovirus (CAstV) isolate PL/G059/2014 into the yolk sac
O
Outcome
Reproduction of the "white chicks" condition (delay and prolongation of hatching, death of embryos/chicks, and change of plumage pigmentation)

The study successfully isolated and reproduced the "white chicks" condition using the PL/G059/2014 strain of Chicken astrovirus, confirming its role as the causative agent.
