RESUMO
BACKGROUND: Tickborne diseases are the most common vectorborne illnesses in the United States. Understanding risk factors for tick bites and adherence to preventive measures are important in preventing morbidity associated with tickborne disease. METHODS: A random-digit-dialing telephone survey was administered to 1820 residents of 11 counties in Tennessee. RESULTS: Of respondents, 16.4% reported a tick bite within the previous year. Only 29% consistently used insect repellant in high-risk situations, and only 54% always checked their bodies for ticks after leaving potentially infested areas. Nearly one fourth of dog owners removed ticks from their pets with bare hands. Dog ownership, rural residence, and exposure to a farm were associated with increased risk of tick bites. CONCLUSIONS: We identified several groups that were at increased risk of tick bites and might benefit from targeted prevention messages.

From 1974 to 1998, 22 isolates of an unusual bacterium, designated as CDC nonoxidizer 1 group (NO-1), were sent to the Centers for Disease Control and Prevention for identification. The organism's phenotypic characteristics were similar to asaccharolytic strains of Acinetobacter, but differed in their cellular morphology and cellular fatty acid profile. We report here on NO-1's clinical and epidemiologic significance. In all cases, isolates were recovered from an animal bite wound; 17 (77%) were isolated from a dog bite wound, 4 (18%) from a cat bite wound, and one (5%) from an unspecified animal bite. Clinical data were retrieved and reviewed for 12 (55%) of the 22 bite victims. None of the patients had pre-existing conditions associated with immunosuppression. Seven (58%) patients were hospitalized for a median stay of 4 days (range, 2 to 11 days). The median time between bite to the worsening of symptoms was 17.5 hours (range, 3 to 78 hours). All patients recovered following antibiotic treatment.
