This research aims to study rickettsioses by identifying the genetic types of bacteria causing these infections in patients from regions of Russia. It is an observational, non-interventional study involving patients who have been diagnosed with or are suspected to have tick-borne rickettsioses. The study collects and analyzes biological samples to better understand the relationship between the bacterial types, patient symptoms, and disease progress. During the study, there is no change or influence on the patients routine treatment or diagnostic process, which follows standard medical care. Residual biological samples such as blood, plasma, buffy coat, serum, or swabs from skin lesions are collected and analyzed for rickettsial genotypes. Medical history, disease progression, symptoms, and treatments are recorded in individual case report forms. The study has received ethical approval and participants provide informed consent. Participants will have their medical history and symptoms documented, along with collection of leftover diagnostic samples. Researchers will perform genetic identification of the rickettsia species within approximately four weeks. The study monitors clinical patterns linked to specific bacterial types while maintaining regular care for patients. Participation involves data and sample collection only, with no experimental treatment. The study is expected to continue until the end of 2026.
