    Borrelia hispanica

    Borrelia hispanica es una especie de espiroqueta endémica de la península ibérica y Marruecos que provoca fiebre reincidente.&#; Su vector son las garrapatas del género Ornithodoros, concretamente la especie O. erraticus.[a]&#;&#;&#;&#; Causa signos meníngeos con cierta frecuencia.[6]&#;

    Epidemiología

    [editar]

    La infección por B. hispanica está probablemente infradiagnosticada, la fiebre reincidente se ha descrito en pocas ocasiones en España (indicencia aproximada de < casos por &#; habitantes al año) y es una especie no cultivable.&#; Es más común en Andalucía, Castilla y León y Extremadura.&#; Un estudio de realizado en la provincia de Kenitra (Marruecos) detectó mediante pruebas de diagnóstico molecularB. hispanica en el &#;% de las personas afectadas por fiebre de origen desconocido.&#;

      Borrelia

      Genus of bacteria

      Borrelia is a genus of bacteria of the spirochete phylum.[1] Several species cause Lyme disease, also called Lyme borreliosis, a zoonotic, vector-borne disease transmitted by ticks. Other species of Borrelia cause relapsing fever, and are transmitted by ticks or lice, depending on the species of bacteria.[2] A few Borrelia species as Candidatus Borrelia mahuryensis harbor intermediate genetic features between Lyme disease and relapsing fever Borrelia.[3] The genus is named after French biologist Amédée Borrel (–), who first documented the distinction between a species of Borrelia, B. anserina, and the other known type of spirochete at the time, Treponema pallidum.[4] This bacterium must be viewed using dark-field microscopy,[5] which make the cells appear white against a dark background. Borrelia species are grown in Barbour-Stoenner-Kelly medium.[5] Of 52 known species of Borrelia, 20 are members of the Lyme disease group (with an additional 3 proposed),[6] 29 belong to the relapsing fever group, and two are members of a genetically distinct third group typ
