Overview

  • Schaalia hyovaginalis, (aka Actinomyces hyovaginalis), is a Gram-positive, non-spore-forming, facultatively anaerobic, non-motile, diphtheroidal bacterium. It has been detected in at least 1 gut microbiome compilation study or metastudy. The DNA G+C content is 63%. Schaalia hyovaginalis is probably a rare gut coloniser. (Collins1993b)



  • This organism has been recovered from porcine genital tract. The risk classification (www.baua.de) for this organism is 2, i.e., risk of individual infection, but low risk of spread (notes: animal pathogen). Pathogenicity status unknown, or very unlikely to be pathogenic. It's gut microbiome symbiotic status is unknown.
