Fibropapillomatosis (FP) is a tumor disease of marine turtles associated with Chelonid herpesvirus 5 (ChHV5) that has historically been refractory to growth in tissue culture. Here, we show for the first time de novo formation of ChHV5-positive intranuclear inclusions in cultured green turtle cells, which is indicative for active lytic replication of the virus. The minimal requirements to achieve lytic replication in cultured cells included 1) either in-vitro culturing of ChHV5-positive tumor biopsies or organotypic cultures consisting of ChHV5-positive turtle fibroblasts in collagen rafts seeded with ChHV5-negative or -positive turtle keratinocytes and 2) keratinocyte maturation, which occurred naturally in explanted...

We reviewed pathological findings and to a lesser extent epidemiological data from 70 free-ranging columbiforms naturally infected with Pigeon paramyxovirus-1 (PPMV-1) from 25 different PPMV-1 mortality events in columbiforms in the USA. In a subset of 17 birds from 10 of the studied outbreaks, we carried out immunohistochemistry targeting PPMV-1 nucleoprotein to determine the tissue distribution of the virus.

Only one virus, Avipox, has been documented in wild birds in Hawaii. Here, using immunohistochemistry and PCR, we found that two native threatened Hawaiian geese, one with multicentric histiocytoma and another with toxoplasmosis and one Laysan albatross with avian pox were infected with reticuloendotheliosis virus (REV). The virus was isolated from one of the geese by cell culture. PCR surveys of other Hawaiian geese with various pathologies, avian pox cases, and pox viral isolates failed to reveal REV suggesting the virus is uncommon, at least in samples examined. The full genome of the Gag, Pol, and Env genes were sequenced for all three infected birds and revealed geographic divergence of the Pol gene suggesting...

Morbillivirus epidemics in marine mammals first gained prominence in 1988 when an outbreak of phocine distemper virus (PDV) occurred in European harbor seals (Phoca vitulina vitulina). Prior to 2001, all serosurveys for morbilliviruses in sea otters (Enhydra lutris) in California, Washington and Alaska documented a 0% seroprevalence. The first published serodetections of morbillivirus in sea otters occurred in 2001–2002 in live-captured Washington sea otters with a documented 80% seroprevalence. We conducted a retrospective study of sea otter cases from 1989–2010 compiled at the U.S. Geological Survey’s National Wildlife Health Center to identify cases of morbilliviral disease in Washington sea otters, and to characterize...
