| human ehrlichiosis: prospective active surveillance in febrile hospitalized patients. | between 1 april 1987 and 30 september 1988 prospective active surveillance of human ehrlichiosis was conducted among febrile patients hospitalized in southeast georgia. if disease of the immune system, bacterial infection, pneumonia, or surgical illness was documented by the end of the first full day of hospitalization, the patient was excluded. of 75 patients enrolled in the study, 8 (10.7%) had a fourfold rise or fall in titer to ehrlichia canis (case-patients). the rate was 5.3 cases/100,000 ... | 1989 | 2809255 |
| molecular and serologic evidence of tick-borne ehrlichiae in three species of lemurs from st. catherines island, georgia, usa. | in recent years, several species of ehrlichiae have been recognized as tick-borne disease agents of veterinary and medical importance. clinically normal free-ranging or previously free-ranging lemurs, including 46 ring-tailed lemurs (lemur catta), six blue-eyed black lemurs (eulemur macaco flavifrons), and four black and white ruffed lemurs (varecia variegata variegata) from st. catherines island, georgia, were tested for evidence of exposure to tick-borne ehrlichiae. all 52 adult lemurs were se ... | 2004 | 15732591 |
| experimental and field studies on the suitability of raccoons (procyon lotor) as hosts for tick-borne pathogens. | we investigated the experimental susceptibility and natural exposure of raccoons (procyon lotor) to five tick-borne pathogens of human and veterinary importance, ehrlichia canis, e. chaffeensis, e. ewingii, anaplasma phagocytophilum (apvariant 1 and ap-ha hge-1 strains), and borrelia lonestari. infections were assessed by polymerase chain reaction (pcr), indirect fluorescent antibody (ifa) testing, and/or culture isolation methods for at least 30 days postinoculation (dpi). two e. chaffeensis-in ... | 2008 | 18429696 |
| the pcs20 pcr assay for ehrlichia ruminantium does not cross-react with the novel deer ehrlichial agent found in white-tailed deer in the united states of america. | white-tailed deer are susceptible to heartwater (ehrlichia [cowdria] ruminantium infection) and are likely to suffer high mortality if the disease spreads to the united states. it is vital, therefore, to validate a highly specific and sensitive detection method for e. ruminantium infection that can be reliably used in testing white-tailed deer, which are reservoirs of antigenically or genetically related agents such as ehrlichia chaffeensis, anaplasma (ehrlichia) phagocytophilum (hge agent) and ... | 2004 | 15373331 |
