| consequences of delayed diagnosis of rocky mountain spotted fever in children--west virginia, michigan, tennessee, and oklahoma, may-july 2000. | patients with rocky mountain spotted fever (rmsf), a tickborne infection caused by rickettsia rickettsii, respond quickly to tetracycline-class antibiotics (e.g., doxycycline) when therapy is started within the first few days of illness; however, untreated rmsf may result in severe illness and death. persons aged <10 years have the highest age-specific incidence of rmsf. this report summarizes the clinical course and outcome of rmsf in four children from four regions of the united states and und ... | 2000 | 11055741 |
| fatal cases of rocky mountain spotted fever in family clusters--three states, 2003. | rocky mountain spotted fever (rmsf), a tickborne infection caused by rickettsia rickettsii and characterized by a rash, has a case-fatality rate as high as 30% in certain untreated patients. even with treatment, hospitalization rates of 72% and case-fatality rates of 4% have been reported. this report summarizes the clinical course of three fatal cases of rmsf in children and related illness in family members during the summer of 2003. these cases underscore the importance of 1) prompt diagnosis ... | 2004 | 15152183 |
| prevalence of antibodies to spotted fever group rickettsia spp. and ehrlichia spp. in coyotes (canis latrans) in oklahoma and texas, usa. | coyotes (canis latrans) are commonly infested with ticks, including amblyomma americanum, the predominant vector of ehrlichia chaffeensis and ehrlichia ewingii; dermacentor variabilis, an important vector of rickettsia rickettsii; and amblyomma maculatum, a major vector of rickettsia parkeri, a spotted fever group (sfg) rickettsia. to determine the degree to which coyotes are infected with or exposed to tick-borne bacterial disease agents, serum samples collected from coyotes in oklahoma and tex ... | 2013 | 23778619 |
| vector-borne infections in tornado-displaced and owner-relinquished dogs in oklahoma, usa. | to determine the prevalence of infection with vector-borne agents in a cross-section of dogs from oklahoma, where canine vector-borne diseases are common, blood samples were evaluated through serology and molecular analysis. antibodies reactive to ehrlichia spp., rickettsia rickettsii, r. montanensis, and "r. amblyommii" were detected in 10.5% (11/105), 74.3% (78/105), 58.1% (61/105), and 55.2% (58/105) of dogs, respectively. presence of spotted fever group rickettsia spp. dna was identified in ... | 2016 | 27119261 |
| "rickettsia amblyommii" and r. montanensis infection in dogs following natural exposure to ticks. | to determine the risk of canine infection with spotted fever group (sfg) rickettsia spp. following natural tick exposure, 10 dogs determined to be free of evidence of exposure to or infection with tick-borne disease agents were exposed to ticks via weekly walks in a wooded area in north-central oklahoma. after each walk, dogs were examined and the number and species of ticks present were recorded. the dogs were then returned to outdoor kennels to allow the infestations and subsequent transmissio ... | 2014 | 24359419 |
