Rosacea is a chronic inflammatory skin disorder that significantly impairs quality of life, however, its pathophysiology is still unclear. Previous studies have suspected that the bacterial -microbiome plays a causative role in the disease. To investigate whether there are differences in the abundance and diversity of facial bacterial microbiomes between rosacea patients and healthy controls. Samples of facial microorganisms from subjects were collected with sterile swabs, and the V3 and V4 regions of bacterial 16S rRNA were amplified and sequenced using the MiSeq platform of the Illumina system. A total of 44 samples qualified (including 17 in the case group and 27 in the control group), comprising 2,048 operational taxonomic units belonging to 40 phyla and 1,312 species that were clustered. The alpha diversity in patients with rosacea was higher than that in healthy controls, but this difference was not statistically significant. In addition, compared with healthy individuals, the mean relative abundance of Cutibacterium acens was significantly lower (61.79% vs 79.69%, p=0.014) and that of Staphylococcus epidermidis was higher (19.64% vs 6.48%, p=0.036) in rosacea patients. Changes in microbial abundance and diversity correlate with the pathogenesis of rosacea.

Another study on bacteria and rosacea which adds cutibacterium acens being LOWER and substantiating other papers that staphylococcus epidermis is higher in the 17  in the case group who had rosacea. No mention of other microbes, which is generally what western medicine focuses on including studies on rosacea. There are three other bacteria that are mentioned in rosacea studies which we list in this category

Wouldn't it be incredible if 10,000 rosaceans got together and each one donated just one dollar and sponsored through a legal non profit organization for rosacea to investigate microbes other than bacteria, i.e., virus, archea, or for that matter whatever the 10,000 rosaceans wanted investigated by a show of hands? Could rosaceans actually come together and do their own rosacea research?
