Morbillivirus infection in cetaceans stranded along the Italian coastline: pathological, immunhistochemical and biomolecular studies.
Following the two Dolphin Morbillivirus (DMV) epidemics occurred in 1990-’92 and in 2006-2008 among Mediterranean Sea striped dolphins (Stenella coeruleoalba), a number of morbilliviral infection (MI) cases with peculiar features were reported in striped dolphins found stranded along the Spanish coa...

Following the two Dolphin Morbillivirus (DMV) epidemics occurred in 1990-’92 and in 2006-2008 among Mediterranean Sea striped dolphins (Stenella coeruleoalba), a number of morbilliviral infection (MI) cases with peculiar features were reported in striped dolphins found stranded along the Spanish coastline. Affected cetaceans showed a subacute-to-chronic, non-suppurative encephalitis, with brain lesions strongly resembling those found in the course of human “subacute sclerosing panencephalitis” and “old dog encephalitis”.
