Ultrastructure of the gastrocnemius tendon and sheath from broilers infected with reovirus.
Gastrocnemius tendon and sheath from male broilers infected with reovirus at 1 day of age were evaluated ultrastructurally at 1, 2, 3, 4, 5, 10, 15, and 20 weeks postinoculation (PI). Although virus particles were not identified, degenerative changes in sheath and tendon fibroblasts were characterized by cytoplasmic vacuolization, disruption of membranes, and loss of ribosomes from rough endoplasmic reticulum, mitochondrial degeneration, and cell disruption.
