Live attenuated RSV strains in particular are difficult to develop due to their poor growth and physical instability, but these obstacles could be avoided by the use of a vaccine vector. [ncbi.nlm.nih.gov]

Apnea and periodic breathing were observed in 1 patient, opsoclonus-myoclonus in another, and disease mimicking herpes encephalitis in the third. All 3 patients recovered without neurologic residua. [ncbi.nlm.nih.gov]

Viral inclusion bodies (IBs), or replication factories, are unique structures generated by viral proteins together with some cellular proteins as a platform for efficient viral replication, but little is known about the mechanism underlying IB formation [ncbi.nlm.nih.gov]

Although ATL cells were not detected in the autopsied lungs and a variety of other tissues, cytoplasmic inclusion bodies, which are commonly observed in RNA viral infection, were abundantly observed in the autopsied lung tissue. [ncbi.nlm.nih.gov]
