Rosacea is a complicated skin disease characterized by excessive inflammation and vascular dysfunction on the face. In addition to the recognized trigger factors, the function of microbiota in the development and exacerbation of rosacea is gaining attention. Microbes related to rosacea include Demodex folliculorum mites, Helicobacter pylori, Staphylococcus epidermidis, Chlamydia pneumonia, and the Demodex-associated bacteria, Bacillus oleronius. However, the findings of research examining their role in the illness have been uneven and equivocal. Microbiological research in many different disciplines has exploded in recent years, thanks to the availability of methods for analyzing complex microbial communities at the taxonomic and phylogenetic levels.
The study offers an update on the microorganisms involved in rosacea and discusses the potential pathogenic function of bacteria in the progression of rosacea.
