| exposure to novel parainfluenza virus and clinical relevance in 2 bottlenose dolphin (tursiops truncatus) populations. | parainfluenza virus (piv) is a leading cause of respiratory infections in humans. a novel virus closely related to human and bovine parainfluenza viruses types 3 (hpiv-3 and bpiv-3), named tursiops truncatus parainfluenza virus type 1 (ttpiv-1), was isolated from a dolphin with respiratory disease. we developed a dolphin-specific elisa to measure acute- and convalescent-phase piv antibodies in dolphins during 1999-2006 with hemograms similar to that of the positive control. piv seroconversion oc ... | 2008 | 18325253 |
| association of an unusual marine mammal mortality event with pseudo-nitzschia spp. blooms along the southern california coastline. | during 2002, 2,239 marine mammals stranded in southern california. this unusual marine mammal stranding event was clustered from april to june and consisted primarily of california sea lions (zalophus californianus) and long-beaked common dolphins (delphinus capensis) with severe neurologic signs. intoxication with domoic acid (da), a marine neurotoxin produced during seasonal blooms of pseudo-nitzschia spp., was suspected. definitively linking harmful algal blooms to large-scale marine mammal m ... | 2009 | 19204340 |
| gaussian mixture model classification of odontocetes in the southern california bight and the gulf of california. | a method for the automatic classification of free-ranging delphinid vocalizations is presented. the vocalizations of short-beaked and long-beaked common (delphinus delphis and delphinus capensis), pacific white-sided (lagenorhynchus obliquidens), and bottlenose (tursiops truncatus) dolphins were recorded in a pelagic environment of the southern california bight and the gulf of california over a period of 4 years. cepstral feature vectors are extracted from call data which contain simultaneous ov ... | 2007 | 17407910 |
| a comparison of several serologic tests to detect antibodies to toxoplasma gondii in naturally exposed bottlenose dolphins (tursiops truncatus). | toxoplasma gondii infection in marine mammals is intriguing and indicative of contamination of the ocean environment and coastal waters with oocysts. in a previous study, 138 of 141 (97.8%) bottlenose dolphins (tursiops truncatus) from the coasts of florida and california had antibodies to t. gondii by the modified agglutination test (mat). although the mat has been found to be highly sensitive and specific for t. gondii antibodies from several species of terrestrial animals, it has not yet been ... | 2005 | 16419751 |
| opportunities for using navy marine mammals to explore associations between organochlorine contaminants and unfavorable effects on reproduction. | the department of defense (dod) has a unique marine mammal program maintained by the us navy that includes the largest force of bottlenose dolphins, tursiops truncatus, worldwide. in recent years, this population of cetaceans that lives in netted open water enclosures in san diego bay has been monitored for levels of organochlorine (oc) contaminants in blubber, blood and milk. data generated from these studies have afforded insight into the fate and possible effects of oc contaminants in marine ... | 2001 | 11453294 |
| coccidioidomycosis in a bottlenose dolphin. | a stranded bottlenose dolphin (tursiops truncatus gilli) succumbed to a pulmonary infection of coccidioides immitis. the dolphin initially presented with mild inspiratory dyspnea that rapidly worsened over 48 hr to include buoyancy abnormalities and finally death. at necropsy, caseous nodules were observed throughout the lungs and perihilar lymph nodes. on histological examination of tissues, double walled organisms containing endospores characteristic of c. immitis were observed in lung, perihi ... | 1998 | 9706575 |
| prevalence of epidermal conditions in california coastal bottlenose dolphins (tursiops truncatus) in monterey bay. | the prevalence of epidermal conditions in a small population of coastal bottlenose dolphins (tursiops truncatus) in monterey bay was evaluated between 2006 and 2008. five different skin condition categories were considered, including pox-like lesions, discoloration, orange film, polygon lesions, and miscellaneous markings. of 147 adults and 42 calves photographically examined, at least 90 and 71%, respectively, were affected by at least one or multiple conditions. pox-like lesions were the most ... | 2010 | 21089999 |
| assessing the potential health impacts of the 2003 and 2007 firestorms on bottlenose dolphins (tursiops trucatus) in san diego bay. | firestorms negatively affected air quality throughout san diego county during 2003 and 2007, including the san diego bay, which houses the navy's bottlenose dolphins (tursiops truncatus). | 2013 | 23905966 |
| nontargeted biomonitoring of halogenated organic compounds in two ecotypes of bottlenose dolphins (tursiops truncatus) from the southern california bight. | targeted environmental monitoring reveals contamination by known chemicals, but may exclude potentially pervasive but unknown compounds. marine mammals are sentinels of persistent and bioaccumulative contaminants due to their longevity and high trophic position. using nontargeted analysis, we constructed a mass spectral library of 327 persistent and bioaccumulative compounds identified in blubber from two ecotypes of common bottlenose dolphins (tursiops truncatus) sampled in the southern califor ... | 2015 | 25526519 |
| newly identified ddt-related compounds accumulating in southern california bottlenose dolphins. | nontargeted gc×gc-tof/ms analysis of blubber from 8 common bottlenose dolphins (tursiops truncatus) inhabiting the southern california bight was performed to identify novel, bioaccumulative ddt-related compounds and to determine their abundance relative to the commonly studied ddt-related compounds. we identified 45 bioaccumulative ddt-related compounds of which the majority (80%) is not typically monitored in environmental media. identified compounds include transformation products, technical m ... | 2016 | 27737539 |
