serological prevalence of tularemia in cottontail rabbits of southern illinois.sera of cottontail rabbits (sylvilagus floridanus) collected in southern illinois in 1983 and 1984 were screened for the presence of antibodies against francisella tularensis by rapid slide agglutination and enzyme linked immunosorbent assay techniques; 6% of 118 and 16% of 119 samples were positive by these methods, respectively. rabbits gained, lost and maintained titers over at least an 8 mo period. francisella tularensis tularensis was isolated from one serologically negative, clinically hea ...19902338733
ecoepidemiology of tularemia in the southcentral united states.we combined county-based data for tularemia incidence from 1990 to 2003 for a nine-state region (arkansas, illinois, indiana, kansas, kentucky, missouri, nebraska, oklahoma, and tennessee) in the southcentral united states with geographic information system (gis)-based environmental data to determine associations between coverage by different habitats (especially dry forest representing suitable tick habitat) and tularemia incidence. high-risk counties (> 1 case per 100,000 person-years) cluster ...200818385353
humoral immune response of cottontail rabbits naturally infected with francisella tularensis in southern illinois.cottontail rabbits (sylvilagus floridanus) usually are thought to succumb to infection with francisella tularensis. reports of a rabbit population from southern illinois (usa) with a high prevalence of f. tularensis antibodies suggested that some cottontails survived infection with this typically fatal bacterium. our goal was to examine the humoral response of cottontails from a study area in southern illinois for which multiple serum samples existed. multiple sera were collected from 79 cottont ...19979391956
