| the distribution and dynamics of rickettsia in the tick population of ohio. | a five-year survey of ticks and associated rickettsia in ohio shows a partitioning of spotted fever group rickettsia (namely, rickettsia montana and r. rickettsii) into three areas of the state where the majority of human spotted fever cases occur. the percentage of ticks infected, even in areas with a high incidence of disease, is remarkably low, less than 1%. the statewide infection rate for r. bellii approaches 3%, and this organism appears to be more evenly distributed throughout the state. ... | 1990 | 2378449 |
| epidemiology of rocky mountain spotted fever in ohio, 1981: serologic evaluation of canines and rickettsial isolation from ticks associated with human case exposure sites. | a survey for the prevalence of rocky mountain spotted fever (rmsf) antibodies in dogs associated with confirmed human cases in ohio was conducted during 1981. twelve of 14 confirmed cases (85%) had a history of dog association prior to onset of rmsf. a total of 29 dogs were included in the study, with 16 dogs providing serum samples for antibody testing and the remainder providing tick samples. serum samples tested by indirect microimmunofluorescence techniques revealed 12/16 dogs (75%) to be se ... | 1984 | 6435461 |
| rocky mountain spotted fever in clermont county, ohio. ii. distribution of population and infected ticks in an endemic area. | the epidemiology of rocky mountain spotted fever (rmsf) in relation to the distribution of the human population and infected ticks has not been defined. a study was undertaken in clermont county, ohio, to describe the distribution of population in a highly endemic focus of rmsf and to determine the prevalence of ticks infected with rickettsiae of the spotted fever group. this area was compared to another area of similar size in the same county where the incidence of rmsf was much lower. the popu ... | 1980 | 7352458 |
