Background: It is not uncommon that a child with a febrile illness of unknown etiology is admitted to the hospital. When the complete blood count reveals a pancytopenia, the diagnostic process can be a real challenge.
Case Presentation: A 13-year girl of Arab-Berber descent presented with abdominal pain and fever after a holiday in northwestern Morocco. A complete blood count revealed a pancytopenia and blood smear test results revealed spirochetes. Borrelia hispanica was identified by sequencing the 16S ribosomal ribonucleic acid gene. Our patient was treated with tetracyclines and during this treatment we saw full clinical and hematological recovery.
Conclusions: Borrelia hispanica is a known cause of tick-borne relapsing fever and is transmitted to humans through the bite of soft ticks of the genus Ornithodoros (Alectorobius). Although the link between tick-borne relapsing fever and thrombocytopenia has been documented, there are only a few case reports of tick-borne relapsing fever presenting with pancytopenia. To the best of our knowledge, there is no previous report of Borrelia hispanica presenting with pancytopenia.

Article Synopsis
- The study investigates the microbiome of tick vectors associated with African swine fever virus and human relapsing fever, revealing how manipulating these microorganisms can reduce the ticks' ability to transmit pathogens.
- Through 16S rRNA amplicon sequencing and metabolic profile predictions, significant differences in microbial composition and diversity were identified between the salivary glands and midguts of different tick species.
- The findings suggest potential candidates for anti-microbiota vaccines, specifically targeting key taxa like Muribaculaceae, to decrease tick fitness and hinder pathogen transmission.

Canine cases of relapsing fever (RF) borreliosis have been described in Israel and the USA, where two RF species, and , can cause similar clinical signs to the in dogs and cats reported from Israel, including fever, lethargy, anorexia, thrombocytopenia, and spirochetemia. In this report, we describe the first clinical cases of two dogs and a cat from Spain (Cordoba, Valencia, and Seville) caused by the RF species Spirochetes were present in the blood smears of all three animals, and clinical signs included lethargy, pale mucosa, anorexia, cachexia, or mild abdominal respiration. Laboratory findings, like thrombocytopenia in both dogs, may have been caused by co-infecting pathogens (i.

We collected data on all TBRF cases in a TBRF-endemic area in southwest Spain during 1994-2016. We analyzed data from 98 patients in whom TBRF was diagnosed by light microscopy and analyzed the relationship between climatic data and TBRF incidence.

BACKGROUND Tick-borne relapsing fever is a disease that is caused by infection with a Borrelia bacterium, and is transmitted by ticks. This infectious disease is characterised by relapsing episodes of high fever, often accompanied by aspecific symptoms. CASE DESCRIPTION We describe the history of a 20-year-old woman who developed recurrent episodes of fever with headache and vomiting after a holiday in Morocco.
