The morbilliviruses recently isolated from two cetacean species in the North and Mediterranean Seas have been shown to differ from phocine distemper virus isolated from European seals using monoclonal antibodies. We have identified a "universal" morbillivirus primer set, based on highly conserved regions of the morbillivirus phosphoprotein (P) gene and used(More)
Serum samples from 288 cetaceans representing 25 species and originating from 11 different countries were collected between 1995 and 1999 and examined for the presence of dolphin morbillivirus (DMV)-specific antibodies by an indirect ELISA (iELISA) (N = 267) or a plaque reduction assay (N = 21). A total of 35 odontocetes were seropositive: three harbour(More)
We reviewed prominent emerging infectious diseases of cetaceans, examined their potential to impact populations, re-assessed zoonotic risk and evaluated the role of environmental stressors. Cetacean morbilliviruses and papillomaviruses as well as Brucella spp. and Toxoplasma gondii are thought to interfere with population abundance by inducing high(More)
In 1990, 74 dusky dolphins (Lagenorhynchus obscurus) and 10 Burmeister's porpoises (Phocoena spinipinnis) were examined for the presence of hyperpigmented marks and pinhole lesions on the skin (tattoo lesions) at the fishing terminal of Pucusana, central Peru. Prevalences of tattoo lesions were 8.1% and 30% in the dolphins and porpoises, respectively.(More)
The restriction map of the bovine herpesvirus 4 (BHV-4) genome (V. Test strain) was established for the restriction enzymes EcoRI, BamHI and HindIII by analysis of clones from a lambda library (Sau3AI partial digestion) and from a plasmid library (EcoRI fragments). One genome unit was defined as the length of the unique central part, flanked at both ends by(More)
The biology of bovine herpesvirus-4 (BHV-4) infection of cattle is reviewed. The infection is distributed worldwide. Most of isolated viruses are non-pathogenic in cattle; some of them are able to produce a genital disease. Twenty-nine structural polypeptides were described; ten of them are glycosylated. Two major glycoproteins were characterized by(More)
Lobomycosis, a disease caused by the uncultivable dimorphic onygenale fungi Lacazia loboi, remains to date as an enigmatic illness, both due to the impossibility of its aetiological agent to be cultured and grown in vitro, as well as because of its unresponsiveness to specific antifungal treatments. It was first described in the 1930s by Brazilian(More)
A previously unidentified morbillivirus was isolated from two harbour porpoises (Phocoena phocoena) that had died in the Dutch Waddensea (North Sea) in 1990. This porpoise morbillivirus (PMV) and a dolphin morbillivirus (DMV), which had recently caused a heavy mortality in Mediterranean striped dolphins (Stenella coeruleoalba), were compared antigenically(More)
We report 1 case of lobomycosis caused by Lacazia loboi in a fisherman and 1 case of lobomycosis-like disease in a bottlenose dolphin (Tursiops truncatus) along the coast of Venezuela. These findings suggest that the marine environment is a likely habitat for L. loboi and a reservoir for infection.
The presence of morbillivirus-specific serum antibodies was examined by an indirect enzyme linked immunosorbent assay (iELISA) and virus neutralization tests in serum samples from 30 dusky dolphins (Lagenorhynchus obscurus), 8 long-snouted common dolphins (Delphinus capensis), 2 inshore and 6 offshore bottlenose dolphins (Tursiops truncatus) and 20(More)
