Background: The etiology of morphea is still unknown. Borrelia spp. as a causative agent of morphea has been discussed since 1985, but the relationship remains uncertain.
Objectives: We aimed to find the frequency of Borrelia in morphea lesions by polymerase chain reaction (PCR) in northeast of Iran.
Patients And Methods: Sixty six patients with morphea were prospectively included in the present study. For each patient, formalin-fixed, paraffin-embedded tissue blocks of skin lesion biopsies were examined for Borrelia spp. DNA using PCR.
Results: No Borrelia DNA was detected by PCR in skin lesions of patients with morphea.
Conclusions: The result of this study showed no relationship between Borrelia infection and morphea lesions and in other word indicated that morphea, at least in Iran, is not caused by Borrelia spp.

The Qinghai Lake National Nature Reserve (QLNNR), renowned for its abundant natural resources and diverse ecological habitats, serves as an ideal environment for ticks, thereby increasing the risk of various tick-borne pathogens (TBPs) transmission. This study aimed to investigate the prevalence of TBPs in ticks collected from Przewalski's gazelle and Tibetan sheep within the QLNNR. A total of 313 tick samples were collected from the vicinity of Qinghai Lake.

Background: Borrelia infection is caused by Borrelia burgdorferi sensu lato and transmitted by Ixodes ricinus ticks, a common tick-borne infection in Northern Europe. The establishment of Borrelia infection depends on transmission of the spirochetes, as well as the immune response generated in the skin after a bite. Here we aim to investigate the local immune response in the skin after a tick bite and assess the possible direct effects of Borrelia, by applying gene expression analysis of the immune response in skin exposed to Borrelia-infected and non-infected ticks, respectively.

Ixodes ricinus tick is a vector of bacteria of Borreliella genus and Borrelia miyamotoi. Exposure to ticks constitutes occupational risk to soldiers, but the current knowledge on this subject is still limited. Therefore, the aim of this study was to evaluate tick abundance and prevalence of infection with Borreliella spp.

Changes in land use, climate, and host community are leading to increased complexity in eco-epidemiological relationships and the emergence of zoonoses. This study investigates the changes in the prevalence of several Ixodes ricinus-transmitted pathogens in questing ticks over a 10-year interval (2011-2013, 2020) in natural and agricultural habitats of the Autonomous Province of Trento (North-eastern Alps), finding an average prevalence of infection of 27.1%.
