Evaluation of clinical specimens for<i>Rickettsia</i>,<i>Bartonella</i>,<i>Borrelia</i>,<i>Coxiella</i>,<i>Anaplasma</i>,<i>Franciscella</i>and<i>Diplorickettsia</i>positivity using serological and molecular biology methods

Abstract

We monitored clinical samples from patients of different age groups from selected regions in Slovakia. Overall seroprevalence evaluated by immunofluorescence (IFA) using nine Bartonella, two Borrelia, six rickettsial (spotted fever and typhus group), two Coxiella, and one human granulocytic ehrlichiosis Anaplasma, Franciscella tularensis and Diplorickettsia massiliensis antigens, in rural and city populations of Slovak Republic, was found to be 32% positive for spotted fever group rickettsiae. Only five (10%) of the rickettsia-positive cases evaluated by IFA were confirmed by polymerase chain reaction. Rickettsia helvetica, Rickettsia slovaca, and Rickettsia raoultii infection appear to be prevalent in Slovakia. Furthermore, Coxiella burnetii, Borrelia and, for the first time, Bartonella elisabethae were confirmed in Slovakia.
