| aerobic microorganisms associated with free-ranging bottlenose dolphins in coastal gulf of mexico and atlantic ocean waters. | our abilities to assess health risks to free-ranging dolphin populations, to treat live-stranded or captive dolphins, and to evaluate the risks of disease transmission between humans and dolphins have suffered from a lack of basic information on microorganisms associated with normal, presumably healthy free-ranging individuals. in order to provide these data, we sampled free-ranging bottlenose dolphins (tursiops truncatus) off florida, texas, and north carolina during 1990-2002. blowhole and ana ... | 2006 | 17092884 |
| saksenaea vasiformis and apophysomyces elegans zygomycotic infections in bottlenose dolphins (tursiops truncatus), a killer whale (orcinus orca), and pacific white-sided dolphins (lagenorhynchus obliquidens). | during a 10-yr period, a killer whale (orcinus orca), two pacific white-sided dolphins (lagenorhynchus obliquidens), and two bottlenose dolphins (tursiops truncatus), all housed at seaworld of texas from 1991 to 2001, were infected with fungi from the class zygomycetes. in four out of five cases, the fungi were identified as either saksenaea vasiformis or apophysomyces elegans. all fungi in the class zygomycetes aggressively invade the vascular system. death occurred within 23 days after the ini ... | 2002 | 12564534 |
| morbilliviral epizootic in bottlenose dolphins of the gulf of mexico. | morbillivirus infection was diagnosed in 35/67 bottlenose dolphins (tursiops truncatus) from the gulf of mexico that stranded from october 1993 through april 1994 in alabama, mississippi, and texas (usa) during periods of increased dolphin strandings in each of the 3 states. diagnosis was based on histologic lesions, immunohistochemical demonstration of mobilliviral antigen, and detection of morbilliviral rna by a reverse transcriptase polymerase chain reaction (rt-pcr) test performed on formali ... | 1996 | 8844569 |
| comparison of elements in bottlenose dolphins stranded on the beaches of texas and florida in the gulf of mexico over a one-year period. | we analyzed tissue samples from bottlenose dolphins (tursiops truncatus) that had stranded on beaches in texas and florida over a 1-year period starting in september 1991. the concentrations of 10 elements plus methyl mercury (mehg) were determined in brain, kidney, and liver, and we examined these results for differences based upon age, site, sex, and tissue type. a strong inverse relationship between total mercury (hg) and the percentage that was mehg was found in liver, kidney, and brain tiss ... | 1999 | 9828266 |
| angiomatosis, a newly recognized disease in atlantic bottlenose dolphins (tursiops truncatus) from the gulf of mexico. | a new disease, angiomatosis, was recognized in 25 of 54 (46.3%) atlantic bottlenose dolphins (tursiops truncatus) necropsied after being stranded along the texas gulf coast during 1991-1996. angiomatosis was first recognized by the authors in 1992 and has increased in incidence and severity, affecting 100% of juveniles and adults. this disease is characterized by proliferation of small, thick-walled blood vessels diffusely throughout the lungs, without inflammation, exudation, or alveolar hemorr ... | 1999 | 9921753 |
| the thyroid gland in bottlenose dolphins (tursiops truncatus) from the texas coast of the gulf of mexico: normal structure and pathological changes. | fresh thyroid glands (n=60) from atlantic bottlenose dolphins that died after stranding along the texas coast between 1991 and 2005 were examined. organ weight ranged from 11 g in a neonate (length 109 cm) to 58 g in a large (249 cm) male. more typical weights were 25-45 g (mean=30.6 g). glands tended to be larger in pregnant and lactating females (mean 37.4 g; n=5) than in non-pregnant animals of comparable size. in infancy, the gland tended to be compact, relatively homogeneous, and sometimes ... | 2006 | 17034811 |
| lobo's disease in a bottlenose dolphin (tursiops truncatus) from matagorda bay, texas. | lobo's disease was diagnosed in a free-ranging male bottlenose dolphin tursiops truncatus examined as part of a live-capture and release program conducted in matagorda bay, texas, usa, during july 1992. diagnosis was based on typical presentation of a raised skin lesion, with sub-epidermal granuloma and demonstration of typical features of the organism by light microscopy, using hematoxylin and eosin, and methenamine silver stains. this is the first instance of lobo's disease found in a dolphin ... | 1993 | 8355355 |
