| pre- and postnatal enzyme capacity for drug metabolite production. | most lipid-soluble foreign compounds including drugs, insecticides and many environmental pollutants are metabolized in animals by cytochrome p-450 enzymes in the endoplasmic reticulum of liver. these enzymes are virtually absent in fetuses of laboratory animals, but their activities increase to adult levels within 3-8 weeks after birth. in human fetuses, the enzymes appear during the first half of pregnancy, and their activities during gestation reach about one third of those found in adults. t ... | 1975 | 1090453 |
| isolation in illinois of a foreign strain of ehrlichia canis, the causative agent of canine ehrlichiosis (tropical canine pancytopenia). | ehrlichiosis (tropical canine pancytopenia) was diagnosed in illinois in a 4 1/2-year-old mixed breed dog that had spent the previous 2 years in india. the dog had periodic epistaxis, anemia, leukopenia, hypoalbuminemia, and hypergammaglobulinemia. a titer of 1:160 for ehrlichia canis was detected by the indirect fluorescent antibody test (ifat). subinoculation of blood into a clinically normal dgo resulted in typical signs of canine ehrlichiosis, and e canis was identified in circulating mononu ... | 1975 | 1112743 |
| experimentally induced infection of dogs, cats, and nonhuman primates with ehrlichia equi, etiologic agent of equine ehrlichiosis. | dogs (german shepherd dogs and beagles), cates, rhesus macaques (macaca mulatta), and baboons (papio anubis) were inoculated with whrlichia equi, the etiologic agent of equine ehrlichiosis. within 3 to 7 days after inoculation, morulae were observed in the eosinophils of cats, neurtrophils of macaques and baboons, and in both neutrophils and eosinophils of dogs. the severe disease produced in horses by this agent was not a feature of e equi infection in dogs, cats, macaques, and baboons. however ... | 1975 | 1115421 |
| platelet kinetics in canine ehrlichiosis: evidence for increased platelet destruction as the cause of thrombocytopenia. | a significant (p < 0.025) increase in the mean platelet diameter occurred in five ehrlichia canis-infected dogs when platelet numbers decreased to 100,000/mul or less. maximal incorporation of [(75)se]selenomethionine into platelets of six uninfected dogs was 0.080 +/- 0.019% (mean +/- standard error) and occurred 5 to 6 days after dosage, whereas maximal incorporation was 0.036 +/- 0.004% within 2 to 3 days after dosage in seven chronically infected dogs that had thrombocytopenia. analysis of t ... | 1975 | 1140846 |
| transmission of ehrlichia canis to dogs by ticks (rhipicephalus sanguineus). | two strains of rhipicephalus sanguineus acquired ehrlichia canis by feeding as either larvae or nymphs on acutely infected dogs and, in subsequent instars, transmitted the agent to normal dogs. three strains of r sanguineus transmitted e canis as adults after their larval and nymphal stages fed on infected dogs. more than 400 adult female ticks were fed on infected dogs as larvae or nymphs or both, but none transmitted e canis transovarially. | 1975 | 1147359 |

| identification of ehrlichia canis in east africa. | ehrlichia canis, the causative agent of canine ehrlichiosis or tropical canine pancytopaenia (tcp) has been identified in kenya. transmission studies to two dogs resulted in signs of ehrlichiosis including marked thrombocytopaenia, pyrexia, reduction in the packed cell volume and the presence of e canis in peripheral blood mononuclear cells. | 1976 | 997191 |
| autologous lymphocyte-mediated cytotoxicity against monocytes in canine ehrlichiosis. | the 51cr-release technique for detecting cytotoxicity had been adapted to immunologic studies of canine ehrlichiosis. lymphocytes from dogs infected with ehrlichia canis, cause of canine ehrlichiosis, were shown to be cytotoxic for autologous monocytes. the effect was dependent on the concentraton of lymphocytes, being optimal at 100:1 lymphocyte:monocyte ratio. neither immune serum and complement, nor anti-canine globulin had any observable effect on cytotoxicity. the monocytotoxicity bore a te ... | 1977 | 931138 |
| canine peritoneal macrophages: cultivation and infection with ehrlichia canis. | canine peritoneal macrophages were obtained by repeated peritoneal lavage of dogs at 14 day intervals. intraperitoneal administration of sterile mineral oil increased the leukocyte yield approximately 20-fold and the macrophage recovery approximately 35-fold. cell recovery was maximum 7 to 21 days after administration of oil and declined slightly by 35 days. restimulation with a 2nd injection of oil promptly revitalized cell recovery. peritoneal macrophage cultures were well established by 6 day ... | 1977 | 931165 |
| acute canine ehrlichiosis: platelet survival and factor 3 assay. | ten dogs experimentally inoculated with ehrlichia canis were thrombocytopenic 14 days after inoculation. circulating platelet concentrations had declined rapidly by postinoculation day 10, but remained at or slightly below the 14-day concentration during the remainder of the 42-day experimental period. the percentage of circulating megathrombocytes also increased to 8.7 times preinoculation concentrations indicating the existence of accelerated thrombocytopoiesis. the release of platelet factor ... | 1977 | 931166 |
| the brown dog tick rhipicephalus sanguineus and the dog as experimental hosts of ehrlichia canis. | adult rhipicephalus sanguineus ticks efficiently transmitted ehrlichia canis to susceptible dogs for 155 days after detachment as engorged nymphs from a dog in the acute phase of ehrlichiosis. adult ticks that had similarly engorged on a dog in the chronic phase of ehrlichiosis failed to transmit e canis to susceptible dogs. infected but unfed adult ticks may be of greater importance than the chronically infected carrier dog as a natural reservoir of e canis. | 1977 | 596693 |
