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
epidemiology and clinical characteristics of tularemia in oklahoma, 1979 to 1985.we studied the clinical and epidemiologic characteristics of tularemia in 165 oklahomans from 1979 to 1985. the ulceroglandular form of the disease was most common (60%), followed by typhoidal (18%), glandular (15%), oropharyngeal (7%), and oculoglandular (1%) forms. the male-female ratio was 3.7:1, and the highest rates of disease were found in the age groups 5 to 14, 35 to 44, and 55 to 74. ticks were most frequently implicated as the source of infection (84/154 [55%]), followed by rabbits, (5 ...19911891728
tularemia - missouri, 2000-2007.tularemia is an uncommon but potentially fatal zoonotic disease caused by the gram-negative coccobacillus francisella tularensis. approximately 40% of all tularemia cases reported to cdc each year occur in arkansas, oklahoma, and missouri. to define the epidemiologic and clinical features of tularemia in missouri, the missouri department of health and senior services (mdhss) analyzed surveillance data and conducted a retrospective clinical chart review of cases that occurred during 2000--2007. t ...200919609248
transmission efficiency of francisella tularensis by adult american dog ticks (acari: ixodidae).the american dog tick, dermacentor variabilis (say) (acari: ixodidae), has been implicated as a potential bridging vector to humans of francisella tularensis, the etiological agent of tularemia. since the initial studies evaluating vector competency of d. variabilis were conducted, f. tularensis has been subdivided into subspecies and clades that differ in their geographical distribution in the united states and in the severity of infections caused in humans. here, we demonstrate that d. variabi ...201121845949
