Aim: To provide healthcare professionals with relevant guidelines for the accurate utilization and comprehension of the origins of eponymic bacterial names when engaging in the genre of MCRs. Materials and Methods: We examined the prevalence of eponymic names of bacteria in the issues of Journal of Medical Case Reports (2007 − 2025) and identified the key patterns of using bacterial nomenclature in this genre. The chosen terminological units underwent assessment through quantitative analysis, structural evaluation, etymological analysis, and contextual examination. Conclusions: The appropriate use of bacterial nomenclature in medical case reports is paramount for the effective communication of clinical findings to colleagues across the globe. It also serves as a means to showcase one’s competence and education in the field. Therefore, it becomes imperative to bring this terminological phenomenon to the attention of students, highlighting its prevalence in contemporary medical case reports.
