| naturally acquired antibodies to tetanus toxin in humans and animals from the galápagos islands. | a serologic survey using a highly sensitive enzyme-linked immunosorbent assay confirmed the anticipated finding of naturally acquired antibodies to tetanus toxin both in humans and animals on the galápagos islands. in 57 inhabitants (mean age, 31.3 years) who had not been vaccinated against tetanus, antibody to tetanus toxin was detected in the blood in varying titers (geometric mean [reciprocal] titer [gmt], 0.015 international units [iu]/ml). in one individual the titer of antibody was greater ... | 1983 | 6827147 |
| intestinal parasites of dogs on the galapagos islands. | dogs on the galapagos islands are a unique population created by isolation from the mainland and regulations prohibiting further importation. the effect of infectious agents of these domestic dogs on the indigenous fauna is largely unknown. the purpose of this study was to determine the prevalence of intestinal parasites in dogs on the galapagos islands. fecal samples were collected from 97 dogs presented during neutering campaigns on santa cruz (n=51), san cristobal (n=17), and isabela (n=29) i ... | 2010 | 20176441 |
| infectious diseases of dogs and cats on isabela island, galapagos. | vaccination and importation of dogs and cats are prohibited in the galapagos, resulting in a uniquely isolated population. the purpose of this study was to determine the prevalence of infectious diseases of dogs and cats that impact their health, could spill over to native wildlife, or sentinel diseases of concern to humans. | 2008 | 18289290 |
| behavioral and physiological adjustments to new predators in an endemic island species, the galápagos marine iguana. | for the past 5 to 15 million years, marine iguanas (amblyrhynchus cristatus), endemic to the galápagos archipelago, experienced relaxed predation pressure and consequently show negligible anti-predator behavior. however, over the past few decades introduced feral cats and dogs started to prey on iguanas on some of the islands. we investigated experimentally whether behavioral and endocrine anti-predator responses changed in response to predator introduction. we hypothesized that flight initiatio ... | 2007 | 17904141 |
