Abstract:Ticks are obligate haematophagous acarines that parasitise every class of vertebrate (including man) and have a worldwide distribution. An increasing awareness of tick-borne diseases among clinicians and scientific researchers has led to the recent description of a number of emerging tick-borne bacterial diseases. Since the identification of Borrelia burgdorferi as the agent of Lyme disease in 1982, 11 tick-borne human bacterial pathogens have been described in Europe. Aetiological diagnosis of tick-transmitte… Show more
“…However, pleocytosis may be absent and specific intrathecal antibodies expressed as antiborrelia antibody index (AI) in paired CSF/serum samples may be negative the first few weeks, and in addition, a positive AI may also persist several months and even years despite appropriate antibiotic treatment (5)(6)(7)(8)(9)(10)(11). Therefore, there is a need for additional markers of ongoing LNB.…”

“…Los especímenes más adecuados para el diagnóstico de rickettsiosis son: sangre con anticoagulante (heparina, EDTA y citrato); suero; biopsia cutánea de las pápulas, vesículas o escara de inoculación; hisopado de la escara; y la propia garrapata (Tabla 1) [19][20][21] . La selección de la muestra dependerá del tipo de diagnóstico solicitado por el médico clínico (serología, técnicas moleculares o cultivo).…”

“…En el caso de que no se vaya a procesar en las siguientes 48 horas, se debe congelar (mínimo a -20 o C). Debido a que la producción de Ac en un paciente afecto de rickettsiosis puede tardar varias semanas, se debe obtener suero en el momento agudo de la enfermedad y en la fase de convalecencia (al menos tras dos semanas) 19,20 . La IFI es usada para detectar las inmunoglobulinas IgM e IgG, tanto en fase aguda como en la convalecencia.…”

“…La IFI es usada para detectar las inmunoglobulinas IgM e IgG, tanto en fase aguda como en la convalecencia. En general, están establecidos como punto de corte títulos de IgG ≥ 1: 64 e IgM ≥ 1: 32 19 . Dado que la prevalencia de Ac en la población sana puede ser elevada, un simple título de Ac no debe considerarse, por sí solo, diagnóstico de infección activa.…”
