Resumen:
This case report provides pathologic and
confirmatory diagnostic documentation of the first reported
clinical epizootic of infectious pancreatic necrosis
(IPN) in farmed rainbow trout Oncorhynchus mykiss from
central Mexico. Both the gross and microscopic pathology
were consistent with IPN. A virus was isolated in cell
culture with the cytopathic effect typical of the IPN virus
(IPNV). Positive identification as IPNV was achieved by
means of an IPNV-specific indirect fluorescent antibody
test and reverse transcription–polymerase chain reaction.
Further genotyping identified this isolate as the Buhl strain
of IPNV, which is a member of the West Buxton (A1)
serotype of aquatic birnavirus serogroup A.
