Het ECDC zegt over relapsing fever dit
Diagnosis in most disease-endemic areas relies on detection of spirochaetes in blood, bone marrow, or cerebrospinal fluid during a febrile episode. During the primary attack, the observation of spirochaetaemia is possible on thin- or thick-blood smears with dark field microscopy or with conventional staining.
Quantitative buffy coat (QBC) fluorescence analysis has also been described as a very sensitive and specific technique for detecting Borrelia in blood. However, this method requires technical expertise, as well as some laboratory infrastructure, and does not identify Borrelia species. Molecular methods are sensitive and used with increasing frequency. They offer the possibility of species identification, even on samples with very low load of spirochaetes. Specific serological assays are, to date, not available for most of the known TBRFs.

Sproetje, bedankt voor het plaatsen van dit interessante artikel.
Wat ik o.a. opmerkelijk vind is deze vermelding;
Tickborne relapsing fever is strictly transmitted by Ornithodoros ticks that are haematophagous at all growing stages. Ornithodoros ticks attach to their hosts for less than one hour, except for some larvae that can stay 1–2 days.
