| development of an indirect immunofluorescence technique for the evaluation of generated antibody titers against erysipelothrix rhusiopathiae in captive bottlenose dolphins (tursiops truncatus). | erysipelothrix rhusiopathiae is the causative agent of erysipelas, a disease of many mammalian and avian species, mainly swine and turkeys. in cetaceans, erysipelas is considered to be the most common infection in juvenile individuals, which have not been vaccinated. moreover, the disease manifest in both forms, the dermatologic and the acute septicemic forms, has been reported in various species of dolphins and whales. it is difficult to diagnose erysipelas by currently available approaches. mo ... | 2014 | 25064337 |
| organochlorine residues in the blubber and liver of bottlenose dolphins (tursiops truncatus) stranded in the canary islands, north atlantic ocean. | polychlorinated biphenyls (pcbs) and chlorinated pesticides: dichlorodiphenyltrichloroethane and its metabolites (ddts), chlordanes (chls), dieldrin, and hexaclorobenzene (hcb) were detected in the blubber and liver of 11 bottlenose dolphins (tursiops truncatus) from the canary islands (north atlantic ocean). samples were obtained from stranded dolphins over the period 1997-2005. among the organochlorines analyzed, pcbs and ddts were predominant in the two tissues, followed in decreasing order b ... | 2008 | 18214918 |
| herpesvirus-associated genital lesions in a stranded striped dolphin (stenella coeruleoalba) in the canary islands, spain. | an adult male striped dolphin (stenella coeruleoalba) stranded alive at arico, tenerife, canary islands, spain. the dolphin died shortly after stranding, and a complete postmortem examination was performed. the most remarkable gross findings were two fleshy masses of approximately 1 cm diameter, near the tip of the penis. these masses were composed of hyperplastic epithelial cells with pigmentary incontinence. ballooning degeneration and margination of chromatin was observed within the stratum c ... | 2015 | 25973629 |
| mercury and selenium status of bottlenose dolphins (tursiops truncatus): a study in stranded animals on the canary islands. | the mercury (hg) level in the marine environment has tripled in recent decades, becoming a great concern because of its high toxic potential. this study reports hg and selenium (se) status, and the first se/hg molar ratio assessment in bottlenose dolphins (tursiops truncatus) inhabiting the waters of the canary islands. total hg and se concentrations were determined in the blubber and liver collected from 30 specimens stranded along the coasts of the archipelago from 1997 to 2013. the median val ... | 2015 | 26232758 |
| levels and profiles of pops (organochlorine pesticides, pcbs, and pahs) in free-ranging common bottlenose dolphins of the canary islands, spain. | the effect of anthropogenic pollution in marine mammals worldwide has become an important issue due to the high concentrations found in many areas. the present study represents the first report of pollutants in free-ranging cetaceans from the canary islands, where there are 12 marine special areas of conservation (sacs), because of the presence of bottlenose dolphins (tursiops truncatus). we selected this resident population of dolphins as a bioindicator to gain knowledge concerning the toxicolo ... | 2014 | 24937489 |
| assessment of the levels of polycyclic aromatic hydrocarbons and organochlorine contaminants in bottlenose dolphins (tursiops truncatus) from the eastern atlantic ocean. | the concentrations of 18 polychlorinated biphenyls (pcbs), 23 organochlorine pesticides (ocps), and 16 polycyclic aromatic hydrocarbons (pahs) were determined in the blubber and liver of 27 bottlenose dolphins (tursiops truncatus) stranded along the canary islands coasts from 1997 to 2011. ddts (mean of 60,960 and 445 ng/g lw., respectively) and pcbs (mean of 47,168 and 628 ng/g lw., respectively) were the predominant compounds in both tissues. among pcbs the highly chlorinated pcb 180, 153 and ... | 2014 | 24726510 |
