Key result

Astrovirus was the most frequently detected enteric virus in turkey poults during the first 4 weeks of life, and experimental infection with astrovirus and RVLV produced enteric disease.

Population

Four flocks from one commercial market-turkey operation in Ohio, and specific-pathogen-free poults

Design

Preclinical

Follow-up

up to at least 7 weeks of age

Authors

Discussion

Implication

Astrovirus may contribute to early turkey enteritis; leaves open its role and control in commercial flocks pending field studies.

Key Points

To determine the incidence and onset timing of enteric viral infections in commercial turkey poults and evaluate the pathological consequences of experimental coinfection.
Monitored four commercial market-turkey flocks from placement through at least 7 weeks of age, conducting frequent fecal sampling during the first 4 weeks.
Inoculated specific-pathogen-free turkey poults experimentally with astrovirus and rotavirus-like virus (RVLV) to evaluate viral shedding order and gross intestinal pathology.
Astrovirus was the most prevalent enteric virus detected during the first 4 weeks of life, followed by RVLV and rotavirus, with initial detections occurring as early as 3 days of age.
Enteric viral detection decreased markedly after 4 weeks of age across all flocks.
Experimental dual infection with astrovirus and RVLV induced clinical diarrhea, sequential viral shedding with astrovirus preceding RVLV, cecal dilation, frothy gaseous luminal contents, and loss of intestinal tone.

Structured PICO

Population

Four flocks of turkey poults from a commercial operation in Ohio monitored from placement to at least 7 weeks of age, plus specific-pathogen-free poults for experimental infection.

Exposure

Experimental infection with astrovirus and rotavirus-like virus (RVLV)

Outcome

Presence of enteric viruses (astrovirus, RVLV, rotavirus) and clinical signs of enteric disease

Astrovirus is a frequently detected early enteric virus in turkey poults that can produce clinical enteric disease when co-infecting with RVLV.

Cite This Study

Reynolds et al. (1987) studied Enteric viral infections. Enteric viruses (astrovirus, rotavirus-like virus, rotavirus) was evaluated on Presence and timing of enteric viruses. Astrovirus was the most frequently detected enteric virus in turkey poults during the first 4 weeks of life, and experimental infection with astrovirus and RVLV produced enteric disease.
