Overview
Alishewanella is a genus of Gram-negative, facultative anaerobic bacteria within the class Gammaproteobacteria. Primarily known as environmental organisms, Alishewanella species have been identified in the microbiome of deep endometriosis — both in vaginal samples and within endometriotic lesions themselves.
The detection of Alishewanella in endometriotic lesion tissue suggests that non-classical environmental bacteria may colonize ectopic endometrial tissue, potentially contributing to local inflammatory microenvironments ([1]). Its presence in both vaginal and lesion compartments supports the hypothesis of bacterial translocation between the lower reproductive tract and peritoneal disease sites ([2]).
