(15) A study in Korean women with rosacea demonstrated a reduction of Peptococcaceae, Methanobrevibacter, Slackia, Coprobacillus, Citrobacter (genus), and Desulfovibrio and an increased amount of Acidaminococcus, Megasphaera, and Lactobacillales in women with rosacea.
Effect of ruminal administration of the lactate-utilizing strain Megasphaera elsdenii (Me) NCIMB 41125 on abrupt or gradual transition from forage to concentrate diets.
Fragments of 340 bp, 341 bp, 343 bp, 344 bp, 345 bp, 347 bp, 349 bp, 353 bp, 354 bp, 356 bp, 361 bp, 363 bp, 368 bp, and 375 bp were classified, respectively, as coming from genera Mycobacterium , Ureaplasma or Mycoplasma , Sneathia , Corynebacterium , Atopobium , Gardnerella , Mobiluncus , Prevotella , Actinomyces , Staphylococcus , Anaerococcus , Peptoniphilus , Megasphaera, and Lactobacillus .
In addition, a number of organisms that seemed associated with BV are uncultivable, for example, species of Eggerthella, Megasphaera, and BVABs members of Clostridiales.
Other organisms that produce Propionate CoA transferase are Megasphaera elsdenii, Bacteroides ruminicola, and Clostridium homopropionicum [29].
Additionally, another study on 257 sputum samples from healthy adults showed that smoking status was significantly correlated with the microbial community structure, and 54 current smokers were significantly enriched in the genera Veillonella and Megasphaera compared with 170 nonsmokers.

Glycerol is metabolized by Megasphaera elsdenii, Streptococcus bovis, and Selenomonas ruminantium (Stewart, Flint, & Bryant, 1997), and Megasphaera elsdenii has been associated with increases in butyric acid in ruminal fluid (Hales et al., 2013).
brewMAP is utilised for the detection of Megasphaera and Pectinatus species, and brewLAP for the pan detection of lactic acid producing species that were developed and validated with the support of key partners who have successfully implemented Veriflow(R) technology at their breweries.
