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 (hernandes 2020 microbiome deep endometriosis vaginal lesion). Its presence in both vaginal and lesion compartments supports the hypothesis of bacterial translocation between the lower reproductive tract and peritoneal disease sites (miyashira 2022 microbiome and endometriosis).
