  1. Seroprevalence and seroconversion for tick-borne diseases in a high-risk population in the disea Northeast United States.

    Article - En anglais

    PURPOSE 

    To determine the prevalence of serologic reactivity, the 1-year incidence of seroconversion, and the frequency of multiple infections, and their associations with symptoms in a group ofvolunteers at high risk for tick-borne infections in New York state.

    METHODS 

    We performed a seroepidemiologic study of Lyme borreliosis, 2 of the ehrlichioses, Rocky Mountain spotted fever, and babesiosis among 671 participants who lived or worked in a high-risk area (mainly in eastern Long Island, New York) for tick-borne diseases.

    Sera were collected in the winters of 1994 and 1995.

    Signs and symptoms of tick-borne disease were monitored monthly by mail and telephone.

    Lyme borreliosis serologies were done by enzyme-linked immunosorbent assay and Western blot.

    Rocky Mountain spotted fever serologies were initially screened using Dip-S-Ticks, followed by specific indirect immunofluorescence.

    Ehrlichiosis serologies were determined by epifluorescent microscopy, as were antibodies to Babesia microti.

    RESULTS 

    Of the 671 participants, 88 (13%) had antibodies to >=1 tick-borne organisms, including 34 (5% of the total) with antibodies to Borrelia burgdorferi.

    Twenty-seven participants had evidence of exposure to B. burgdorferi at baseline.

    Seven participants (1%) seroconverted during the course of the study, 5 of whom were symptomatic for Lyme borreliosis. (...)
