“…Borrelia burgdorferi s.l . has been reported in mainland France, continental Italy, Spain (Hubálek & Halouzka, ), and also in the cooler areas of North Africa (Tunisia, Algeria and Morocco; Benredjem, Leulmi, Bitam, Raoult, & Parola, ), but has not been found in ticks from Sardinia and Sicily, two Mediterranean islands with a drier climate than Corsica. Recently, it was reported in I. ricinus collected from rats in Corsica (Cicculli, Capai, et al, ), but without determining the exact species.…”

Corsica is a mountainous French island in the north‐west of the Mediterranean Sea presenting a large diversity of natural environments where many interactions between humans, domestic animals and wild fauna occur. Despite this favourable context, tick‐borne pathogens (TBPs) have not systematically been investigated. In this study, a large number of TBPs were screened in ticks collected over a period of one year from domestic and wild hosts in Corsica. More than 1,500 ticks belonging to nine species and five genera (Rhipicephalus, Hyalomma, Dermacentor, Ixodes and Haemaphysalis) were analysed individually or pooled (by species, gender, host and locality). A real‐time microfluidic PCR was used for high‐throughput screening of TBP DNA. This advanced methodology enabled the simultaneous detection of 29 bacterial and 12 parasitic species (including Borrelia, Anaplasma, Ehrlichia, Rickettsia, Bartonella, Candidatus Neoehrlichia, Coxiella, Francisella, Babesia and Theileria). The Crimean–Congo haemorrhagic fever (CCHF) virus was investigated individually in tick species known to be vectors or carriers of this virus. In almost half of the tick pools (48%), DNA from at least one pathogen was detected and eleven species of TBPs from six genera were reported. TBPs were found in ticks from all collected hosts and were present in more than 80% of the investigated area. The detection of DNA of certain species confirmed the previous identification of these pathogens in Corsica, such as Rickettsia aeschlimannii (23% of pools), Rickettsia slovaca (5%), Anaplasma marginale (4%) and Theileria equi (0.4%), but most TBP DNA identified had not previously been reported in Corsican ticks. This included Anaplasma phagocytophilum (16%), Rickettsia helvetica (1%), Borrelia afzelii (0.7%), Borrelia miyamotoi (1%), Bartonella henselae (2%), Babesia bigemina (2%) and Babesia ovis (0.5%). The high tick infection rate and the diversity of TBPs reported in this study highlight the probable role of animals as reservoir hosts of zoonotic pathogens and human exposure to TBPs in Corsica.

“…Rickettsia species (the majority is represented by R. Helvetica and monacensis) is another agent of possible coinfection [88,89]. The clinical onset of rickettsiosis is characterized by fever and a small papule of 1-1.5 cm in diameter that developed in a small ulcer with a dark crust that leaves a scar when it heals.…”

Borrelia burgdorferi is highly susceptible to antibiotic treatment and the majority of patients profit from this treatment. Antibiotic selection, dose and route of administration, and duration of therapy for Lyme disease depend on the patient's clinical manifestations and stage of disease, age, pregnancy status, as well as the presence of other concomitant diseases and/or allergies. Despite an appropriate antibiotic therapy, about 10-20% of patients may show persistent or recurrent symptoms ("post-treatment Lyme disease syndrome").In the present paper we will briefly discuss the post-exposure prophylaxis, before going on to talk over the current therapeutic approach regarding the management of Lyme disease according to the stage of disease/clinical manifestations. Finally, we will discuss the main treatment-related phenomenon, the Jarisch-Herxheimer reaction, and the treatment modalities for special categories of patients, namely pregnant women, subjects suffering from post-treatment Lyme disease syndrome, possible Borrelia-associated skin manifestations, coinfections and Baggio-Yoshinary syndrome.
