| evidence of helicobacter sp. in dental plaque of captive dolphins (tursiops gephyreus). | gastrointestinal lesions have been extensively reported in wild and captive marine mammals. however, their etiology remains unclear. in humans and other animals, chronic gastritis and peptic ulcers have been associated with helicobacter sp. therefore, the aim of our study was to investigate the presence of helicobacter sp. in the gastric juice, dental plaque, and saliva of marine mammals living in a controlled environment. five dolphins (tursiops gephyreus), one killer whale (orcinus orca), one ... | 2002 | 12238390 |
| novel gastric helicobacters and oral campylobacters are present in captive and wild cetaceans. | the mammalian gastric and oral mucosa may be colonized by mixed helicobacter and campylobacter species, respectively, in individual animals. to better characterize the presence and distribution of helicobacter and campylobacter among marine mammals, we used pcr and 16s rdna sequence analysis to examine gastric and oral samples from ten dolphins (tursiops gephyreus), one killer whale (orcinus orca), one false killer whale (pseudorca crassidens), and three wild la plata river dolphins (pontoporia ... | 2011 | 21592686 |
| environmental contamination and marine mammals in coastal waters from argentina: an overview. | environmental contamination become an increasing global problem. different scientific strategies have been developed in order to assess the impact of pollutants on marine ecosystems. the distribution of toxic contaminants in tissues of different marine mammal species--both cetaceans and pinnipeds--has been studied in many ecosystems, as well as several related ecological processes, like pollutant accumulation or transfer through the food web. a research program directed towards evaluating the oc ... | 1994 | 7973603 |
