Oral inoculation with entero-like viruses and field materials caused abnormal faeces and reduced weight gain in chickens, whereas reoviruses and parvoviruses alone did not.
Entero-like viruses, rather than reoviruses or parvoviruses alone, appear to be involved in the aetiology of runting syndrome and weight gain depression in chickens.
Entero-like viruses may contribute to runting in poultry; leaves open confirmation in commercial flocks and targeted interventions.
Specific-pathogen-free White Leghorn chickens and commercial broilers were inoculated orally at 1 day of age with different intestinal preparations containing a chicken parvovirus, an entero-like virus associated with a reovirus from field materials, or the entero-like viruses and reovirus alone. Despite viral multiplication in inoculated birds, no clinical signs or growth retardation were observed in SPF and broiler chickens infected with the reo or parvoviruses. Abnormal faeces and reduction in weight gains were observed after infection with the field materials and the entero-like viruses. Some easily sedimentable particles could be involved with the entero-like virus in the aetiology of runting syndrome. Proventriculitis was present in chickens inoculated with one of the field materials and with the entero-like virus isolated from that material. Specific-pathogen-free White Leghorn chickens were as susceptible as commercial broiler chickens to weight gain depression after oral inoculation with crude homogenates at 1 day of age.

Decaesstecker et al. (1986) studied Chicken malabsorption syndrome. Oral inoculation with intestinal preparations containing chicken parvovirus, entero-like virus, and/or reovirus was evaluated on Clinical signs, growth retardation, abnormal faeces, and proventriculitis. Oral inoculation with entero-like viruses and field materials caused abnormal faeces and reduced weight gain in chickens, whereas reoviruses and parvoviruses alone did not.
